You, sir have put UVB explanation in to the most digestible way I’ve ever seen, outstanding! I’ve been working with reptiles for about 8 yrs now and I still get tripped up on how to explain this part of lighting. I’m so excited to share your vid with others :)
@@j_ddm4v737 based on my research and discussion with others over the years, for most setups linear uvb is the best. But always research for yourself and compare your own husbandry when making this decision. :)
I think in the 1year that I have been a beardie owner, this has been the most informal video that actually helps me to understand the uvb levels and numbers. Thank you for this!!!
you see? these are the people we need in our petcos, not the people that dont know the difference between a crested gecko and a house gecko edit:ik this isnt a petco just sayin
Finally! I understand the differences in the bulbs! Ive been keeping reptiles for 7+ years, and honestly the lighting aspect has never been my strong suit. Ive had to rely on reputable internet care guides(heavy emphasis on reputable), vet and breeder advice. There arent many clear, factual, explainations that arent sponsor biased that I have found. Thanks so much!
This was an excellent video on uvb lighting. It should be required viewing for all starting the reptile hobby. Super duper easy to understand. If there were academy awards for youtube this should get nominated. Great job guys.
This video is less than 10 minutes long and you managed to cover pretty much everything in a thorough but digestible manner. Damn I litterally could have saved so much time if I just watched this video first. Thanks!
Wow! Thank you Matt for a great lesson on lighting. I was so confused with all the bulb types out there and what exactly I would need. Your clear and concise video really helped. Nice looking store too. Thanks and take care.
I just called this place and the lady was amazing!!! I wish I lived so much closer but its not that far. She told me about lighting and offered to help me when I came in. Awesome place!!!
Dude this video is top notch. Really, awesome job explaining everything and showing the different products, without any fluff or filler. Super interesting!
It's absolutely necessary. In the wild, they'd have exposure to the sun, that allows them to regulate bodily functions and Vitamin D synthesis. We have to do our best to replicate it in captivity. Without it, they will eventually stop eating, suffer from metabolic bone disease as they can no longer absorb calcium, and eventually, death. Reptiles, for the most part, are essentially solar powered.
I'm new to this reptile world especially bearded dragon and planning to get one soon, and i Can't find any better videos about uv lights thn yours ! This is by far the best explanation about uv lights for reptile , thank you so much !
Thank you for a straightforward, simple way of understanding all this. Now, I know that UVB lights can be checked with an expensive meter to see if they're still making UVB, but do you by chance know of a type of rock or everyday household item that we can hold under the flouresence UVB bulb to see if it's still emitting UVB rays? I'm googling and can't find anything yet-- but surely there is! To maybe use instead of a pricey meter that would let us check from home?
Unfortunately any of the objects marketed as reading UVB like the cards or stickers, etc. on a color scale are not very accurate. They may read there is still UVB output but it may be at a much lower (or even higher) level than what your reptile requires. The only way to get an accurate measurement on UVB bulbs is with a Solarmeter. The meters can often quickly pay for themselves however, as you can replace bulbs as needed and not just on a 6-12 month schedule.
Ok this was probably the best video I’ve seen on the difference of UBV bulbs! I got my bearded dragon that’s my first reptile about 6 months ago and tbh I’m learning as I go!
Matt - I have to thank you so much for posting/making this video! It literally saved my Chams life! I am new to reptile keeping and have always wanted a veiled chameleon. I recognize they are not recommended as a first reptile so I did so much research and thought I was well informed, educated and prepared to raise one. I bought one from a local pet store (which I know is always advised against doing) but this particular one called to me. She is such a sweet girl. About a month into having her I noticed one day she was super shaky and weak while trying to walk. I immediately started researching MBD and your video popped up when I was researching lighting. I went out and purchased the mercury vapor bulb and made some other changes to her enclosure and she is improving nicely in a weeks time!! I really didnt understand the difference and how much different they actually are AND since I changed those things she has been bright green!! I am so thankful to you for providing this (and in layman's terms) easy to understand and vital information! Thank you from me and Zuri!! 🦎❤
@@11SEXMACHINE She is doing beautifully!! Thanks for asking. I just upgraded her enclosure so I think she will be happy about that once I get it all set up. I have a question maybe you can answer. She always wants to come out of her enclosure to just sit on my hand (or my head ha ha ha). How long is it safe to keep her out? I cant seem to find that info anywhere?
It can vary a little bit with your room temperature, etc, but we find using the 160 watt Solar Glo on our 40 gallon tanks tends to be perfect for our dragons. You might need to raise or lower the bulb or the basking area to get the temperature exactly where you need it. Lots of bearded dragon owners have been gravitating towards using linear T5 UVB bulbs and separate heat as well, since that way you can offer an area with both, an area with just UVB, and an area with no lighting.
I've seen a lot of videos about reptile lighting and this one is on point. I've had my baby beardie for two days. I purchased a 20 gal tank kit for now. I was clueless about what type bulbs to get for a bearded dragon nor did I understand what the 5.0 meant. Thanks, your video was very helpful and informative
so you covered how far the UVB pen's but is getting it to close bad? Im doing a 4x2x2 with a Uromastyx and I am having issues finding out the best way to go with UVB bulbs go and Basking. I was looking into the Vapor mercury since I can get heat and UVB but I need like 115-120f on the basking
You just add another heat bulb next to the MVB, like a halogen. Placing a UVB bulb closer to the animal than the recommended range can damage your reptiles eyes and cause severe burns. It's the wavelength that is primarily responsible for sunburns.
@@TyeDyedIguana Thanks for the fast response. Im looking at doing a ARCADIA PROT5 14% UVB 36" in the 4x2x2 and a basking bulb would that be a better option not factoring price? With that setup would you put the UVB more center since its a 36" or opposite the basking?
@@brmcdonald68s1 If you're going to use a linear UVB bulb, you'll want it to overlap the basking area. The idea is that you're mimicking a sun patch for them to bask in, so you want an area where they can get their heat and UV in one spot. The opposite end should have no light, so they have a cooler, darker area if they'd prefer. Either set up will work, but you'll probably still need the power of two basking bulbs with the linear light.
you said that the "solar glo" mercury vapor bulbs have three feet of penetration, yet you also said that they are perfect for a bearded dragon in a 2 foot tall enclosure. Wouldn't they be too much for a 2 foot enclosure then? I guess it depends on how high above the lid you mount the light? It seems like it'd be to much for setting right on top of the lid, or inside the tank @4:50
These bulbs do have 3ft of penetration, but at 3ft, you'll have less UVB output than at 2ft at the basking spot. The 3ft mark is the maximum amount of distance from the basking spot before you basically don't have any UVB benefit. The distance depends on the animal you're keeping. At 3ft, it may be great for a tropical animal, but at 2ft, it's better for a desert animal.
Matt, SO I just received a 75GAL tank/stand/canopy W/LED lights combo from my Wife as an early X-Mas present. I'm planning on building an acrylic ATBA W/solvent welded seams, a large ramp, and a large piece of dark slate for my future turtles to bask on. I already know that I want to use a mercury vapor bulb. I also know that I want to make my ATBA roughly 1FT high, and will most likely use a ceramic socket clip on light fixture, clipped to the top of the ATBA, putting my bulb roughly a foot from my future turtles. I'll be getting a male Black-Knobbed Map and a male Pearl River Map hatchling. Knowing all of this, what wattage of mercury vapor bulb should I use?
Depending on the room temperature, you'd be looking at an 80 watt, possibly 100. It may require a little trial and error. Keep in mind that anytime you're cohabitating animals, you'll need to watch for competitive or territorial behavior.
Not all glass is the same! There are lots of different types and they filter UV differently. The glass commonly used in homes, for example, filters too much to be of benefit to our reptiles. UVB bulbs are designed with a special type that allows UV to pass through.
@@TyeDyedIguana what if i get an ordinary metal halide bulb and remove the outerr glass? Will that be the same as an uvb lamp since the interior ark bulb is made of quartz and it doesnt block uv
@@Anktual We don't recommend using anything other than UVB reptile bulbs manufactured by companies like Zoo Med or Exo Terra. These are manufactured specifically for levels of UVB that are appropriate for the reptile's health. Modified or off-brand bulbs are a risk for dangerous levels of UV or not enough. We've seen instances of burns, eye damage, or metabolic bone disease from using inappropriate bulbs.
For the solar glow from exoterra, could you please please please please please explain which wattage Mercury bulb I should buy depending on the height of my tortoise table?!
We use the 160w bulbs on all our tortoises here. You may need to raise or lower the bulb to reach the correct temperatures on your tortoise's basking spot, or in the case of a larger enclosure, use more than one bulb.
Tye-Dyed Iguana thank you so much! I was already wanting to get a solar glo and this video sold me☺️while I’m here I should ask, what’s the minimum size tortoise table for a fully grown Russian tortoise and what’s the best substrate for them?
We do have a video that explains more in depth on their care, but we consider the minimum to be 36 x 18 x 16, or a 40 gallon. In the case of a tortoise table, you have the freedom of a custom made enclosure, so we recommend making it bigger if you can! Fir bark, coconut fiber, or a mix of peat moss or sand can be used as a substrate.
T5's are becoming the new normal when it comes to lighting. They're stronger and penetrate better than the T8's. T8's are getting harder and harder to find. We still sell the bulbs, but we do not offer the T8 fixtures.
Pretty much any UVB bulb (like the compact or tube lights) that isn't a mercury vapor bulb is UVB only, and would require a separate bulb if you need heat.
All of our available bulbs are here : thetyedyediguana.com/light-bulbs/uvb-bulbs/ Anything on those pages that isn't a mercury vapor bulb is UVB only. The size and output of your UVB bulb will depend on your enclosure and what type of animal you have.
@@TyeDyedIguana There is discrepancy in your claim: The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm). www.who.int/news-room/q-a-detail/radiation-ultraviolet-(uv) Here is the bulb manufacturer spectrum output for the "New Spectrum! Former Repti Glo 5.0": www.exo-terra.com/en/products/reptile_uvb100.php The graph clearly shows higher power output in the UVA range than in the UVB range.
We don't have anything specifically splash proof for UVB, but most people go for either the florescent tube style or compact. Tube lighting will give you better coverage. You'll just need to be careful with the bulb, but generally the hotter the bulb runs, the more susceptible it is to shattering from water. UVB bulbs don't produce much heat.
Excellent video but I still need help. I built a tank for my bearded dragon that is 41"L x 20"D x 18"H and I bought a T5 HO 36" Reptisun Hood and I want to install it inside the tank, is this the correct size hood and also should I use the 5.0 or the 10.0? Thank you so much for your help.
Typically for a bearded dragon, you want the length of the UVB to go across about 1/2 to 2/3rds of the length of the enclosure. The 10.0 would be right for a desert animal, the 5.0 is more suitable for tropical animals.
I have a 5 x 2 x 2 large enclosure for an Australian Water Dragon. I only need a 95 degree hot spot...rest of the tank about 80. I need a combo UVB/heat bulb. How much wattage?
It's going to depend on quite a few factors, so you may have to try a few different wattages or setups to get it right. It may change whether or not the bulb is installed inside the enclosure, or sitting on the top through mesh, the distance between the bulb and the basking area, the ambient temperatures inside your house...you get the idea. So I would say start with a 160w if it's sitting on mesh or away from the basking spot. If it's mounted closer and inside the enclosure, there's a chance it'll be too hot, so you can always bump it down to a 100w if it is.
@@TyeDyedIguana - I think 100 might be enough. There is a screen the light has to go through but the cage is set up in a way that the light is right over top of the basking spot and not a huge distance. I had an 85 Watt Powersun bulb I had from a while ago and the basking spot was about at 90. Since they only need a 95 degree basking spot and the rest at 80, the 100 watt Powersun might be enough. Since it is a large tank, I might put some normal heat bulb on other side just to keep temps up high in enclosure as a hole. It is a 5 x 2 x 2 Showcase Cage.
question.. so between the t5 & t8 varieties do you recommend one over the other? i keep hearing that the t5 doesn't flicker so therefore its better.. im building a 4'x2'x2' enclosure for my beardie & will be mounting im guessing a 34" (since the bulbs come in weird lengths) im worried that the t5 may be too small for such a large enclosure.. what would you recommend? any input would be greatly appreciated! originally i was just going to put a mvb for day & a ceramic heat emitter for night.. i have since decided the tube uvb would be a better route & to just keep my house above 65°[sigh] im just struggling on deciding which fixture to buy for the uvb. its going to be mounted inside the enclosure. if anyone could chime in it would be appreciated. thanks!
For a desert animal, you may have better luck with the T5. They are higher output and the stronger bulb out of the two, and being that it is smaller along with the better output, gives you more flexibility.
Great video man!! Been looking to see which bulb is best for my bearded dragon in a 40 gallon tank. Only for now I know he needs a much bigger tank to be content.
Great Job Matt!!!!!! Great facts! Watching this video of Matt being a reptile genius literally just made my day, just fell and busted my lip open on ice in my back yard😂 -Noah
So from the screen to the floor of my leopard gecko s tank is 12 inches.... Would i go with a 5.0?? Seems possible that a 10.0 would be too much.... Hoping i get an answer
A 5.0 would be appropriate, a 10.0 too much. Leopard geckos are crepuscular, meaning most of their activity is at dawn and dusk. They wouldn't be out in full desert sun.
I'm building a paludarium that's 3 ft tall for a rhino rat snake. Trying to figure out which lights (if more than one) for the plants as well as heating. Any suggestions?
Typically plants will do better with an addition of an LED strip light - though it's important not to overwhelm the animal with lights that are too bright or unnaturally colored like the purple grow lights. Some reptile UVB lighting fixtures also come with LED lights.
@@TyeDyedIguana went with the Arcadia jungle dawn for the plants. I'm a little confused with the uvb, was gonna get the shade dweller for uvb...would I still need a heat lamp. This has been a big learning process but i wanna nail it.
Can i used the zilla t8 on my 36" x 18" x 18" 40gallons tank for my leopard geckos? & one of exo terra 36" x 18" x 12" for a bioactive for a red eye crocodile skin?
Yes. For both of these animals, you can use a low strength linear UVB light during the daytime. You want bulbs marketed for tropical or shade dwelling species.
@@TyeDyedIguana thank you so much i really i appreciate it! I been made some updates to my tanks and I'll put them in a metal shelves but i need to change all my light's to low profile i have i few already from zilla the single one with a bulb of 6w for the small ones, 10 & 20 gallons but i need to change the lights for the big one and i just want to make sure the i do the best for them. Thank so much!
hey matt i have 2 juvi green iguanas under a year old. they are housed (temporary )in a 35gallon hex tank with crape myrtle branches running across diagonally to give them a high place to perch , we also have a metal screen top cover . at the moment i have a cheap uv/60 watt sitting on the mesh along with a heat emitter( i leave on 24/7 for temp) the depth is 22" top to bottom should i shoot for the upper half of the enclosure for depth penetration (ie bake them with a 5.0 or mercury vapor ? i dont want to over expose them or should i get the 10.0 and get to the bottom of the tank as well. thanks
Usually when we measure for target heat and UVB, we measure from wherever they have their basking spot set up. So if the basking spot, like a branch, is up from the ground, that's where you'll make sure you would hit your ideal temperatures and UVB readings.
It's thought that snakes do not require UVB as the majority of them are nocturnal. They are usually only supplied with a heat source. However, lots of people are of the thought that adding low levels of UVB during the day for even nocturnal animals can be beneficial. Quite a few of them can be seen during the day basking. If you would like to add a UVB light to your snake's enclosure, we recommend a lower output bulb like a 5.0.
No. Most glass blocks most to all UVB light. UVB bulbs are designed to go over mesh screen, which will block a percentage of UVB, but not all, or installed inside the enclosure depending on the set up.
You just confirmed my worries I bought my baby corn snake at a chain store in which I work the salon and for anzoomed 25 gallon reptihabitat I believe 30 x 16 x 13 with screen blue daylight 100 watt for heat and when I insisted it needed uvb a thrive brand uvb 5.0 I need to double check but I think 25 watt the micro bulb things and I was finding the blue daylight didn’t give it any kind of a gradient and even at 100 watt wouldn’t get me an 85-90 basking and not much different from the cool to hot side so I went to a 75 watt reptibasking light for heat and basking seems o fix the hot spot and gradient but I’ve been worried about the uvb btw the uvb and basking are in a dual fixture by thrive and I remember having a beardie with a 4 x 2 x2 with a t8 built into the tank around the middle completely away from the heat and basking so I was trying to figure if it’s safe being side by side and using the compact or if I needed a t8 5.0 moved over a bit and this is clear with my screen I need to upgrade to a 10.0 wether in the same spot compact or t8 and moved over this may explain which my snake while seemingly healthy great eater and handles well stays hydrated is always under its hide and water with this info would u recommend sticking with the compact and at what wattage just switching to a 10.0 or upping to the reprising t 8 10.0 18 inch I’ve been looking at prior to this video I was looking at the reptisin 18 inch 5.0 but I think ur video made it clear with my screen top 16 inch to floor 5.0 simply does not cut it
Corn snakes do not need much UVB, they bask more cryptically and the 10.0 is intended for desert animals. Stick with a 5.0 bulb or something similar labeled as either tropical or shade dweller.
For my 48 x 18 x 18 bearded dragon tank will the reptisun t5 ho fixture with a 10.0 tube provide proper uvb when placed on top (screen lid)and what should the length be I’ve gotten mixed advice some say the full length and others say 2/3s the length ?
Yes, for a bearded dragon, the 10.0 tube is recommended. Make sure you have a raised basking spot for him as a mesh screen will dramatically cut down on your UVB output. On our enclosures where we use UVB tubes, we do the full length of the tank. Not only can they get the benefit no matter where they are in the enclosure, it looks a little nicer.
None of our bulbs have been rated or tested for use on humans, only reptiles. We can't vouch for either the efficiency or safety of their use on humans. We recommend consulting with a medical professional in this case.
What can I use for a baby turtle ? I had got a flukers clamp lamp for heating but I need a uvb light but some say to get both uva and uvb someone help please 😭 I have a screen on my turtle aquarium I was thinking of getting a outside basking area too
UVB bulbs output both UVA and UVB. You need a heat bulb and a UVB bulb. Since aquatic turtle basking spots are usually pretty close to the light, you can use either a compact UVB bulb or if it's a little further away, a T5HO fixture. You'll want to get UVB bulbs that are labeled as tropical, generally. That'll be a 5.0 or 5%-6% bulb, depending on the brand.
The reptile branded T5 fixtures are what we recommend. They are built with reflectors that help to strengthen the amount of light that is projected downwards toward the enclosure. The estimated output the companies put on the boxes are based on using those fixtures and they may not be efficient enough using an off-brand fixture.
I have a 100w MVB for my juvenile beardie who is in a 40g breeder with one of those double domed fixture. But it definitely didnt give a warm enough basking spot so i put a basking bulb in the other socket.
I’m a first time owner of a bearded dragon he kind of just got landed on me so I plan on buying him a bigger tank but I’m not sure if I should get 2 UVB lights and 2 basking for 120 gal tank
That would all depend on the set-up of your enclosure, and the bulbs in question. We find that one long linear UVB, can suffice. For larger tanks needing extra heat, we do find that an additional low wattage bulb or ceramic heat emitter can be beneficial, attaching your heat sources to a thermostat is the best way to ensure consistent and proper heating 😊💡
We use mercury vapor bulbs with a lot of success with our tortoises, but we can't make a suggestion without an idea of how far the bulb would be from the basking spot.
Any of the mercury vapor bulbs will provide UVB for a basking spot. You do not need an extra bulb for UVB unless you want more coverage across the enclosure.
Also I made a homemade fish filter. I used a submersible pump and I'm forcing water through the INSIDE of the carbon filter. I put an aerator directly underneath it stuck to the glass and the spin of the pump wheel...is hyper oxygenating the water. Fun little breeder and store owner tips tricks hints and pointers. I'm making a pvc grid with a tank liner over the top of it then up the corner of the tank to a halo, that's been Bernoullied. So the holes near the exhaust of the water tube at the top of the tank are smaller and gradually get larger to spread the pressure and output of each outputhole the same g.p.h. all the way around the tankhalo. Really only aquaculturiats use stuff like this but I'm a modfreak. I believe strongly in products that function PROPERLY. Simile, gracefully, like 3M. ;) and if I ever didn't thank you. Thank you.
do they have a datasheet with the spectrum? i am looking for a light bulb that delivers a lot of power in the wave length of 295-320nm because that is the wavelength where the body produces the most vitamin d
We do not have a concise data sheet for every single bulb we have available. What we can say is that providing the bulb recommended for your animal and a basking spot at the proper distance will give them adequate UVB levels for D3 production. Any data that the manufacturers have provided about wavelengths is usually available on their individual websites.
Young Hermann’s Tortoises must have a minimum cage size of 36” Long x 18” Deep X 16” High. An adult should be housed in a 6’ long x 3’ deep enclosure. An ambient temperature gradient of 75-85F and a hotspot of 95F is ideal, with a UVB source emitting between 10-12% UVB. We strongly encourage linear UVB bulbs, such as a T5 or T8 whenever possible, as they cover the most space and seem to be most efficient. Mercury vapor bulbs are another option that emits heat and UVB in one source. Specific lightbulb types, to achieve this, can vary depending on your set-up size and dimensions. As larger set-ups may need a stronger wattage to achieve desired readings. What kind of enclosure do you have for your tortoise?
It depends on the sort of animal you're going for, but if you're wanting stronger UVB the T5 is the way to go. If you can mount the lighting on the other side of the screen - go for it. Screens block out quite a bit of the UVB but sometimes it just isn't possible to set it up on the inside with many premade enclosures on the market. The result is then the basking spot needs to be closer to the light if the screen is between the animal and the light.
@@TyeDyedIguana It will be for a bearded dragon. So I need to place both UVB T5 and the solar glo 160 W under the screen. I do believe it has a place I can hang them.
So for my tank I have a 40 gallon zoo med tank and I was wondering if I should use the UVB stick or if I should use the bulb that came in the kit (it’s in a dome attached the the heat bulb and it’s the 40 gallon zoo med kit if you know what that is). Also when I turn on the light it shows light in the whole tank.. so should I keep this or get the stick? Stay safe everyone!
The long UVB bulbs are preferred by many keepers as it allows the animal to get UVB in more areas than the basking spot. The compact bulbs are more limited in their coverage area but are good for smaller tanks.
The strength will depend on the species and how the enclosure is set up, amount of foliage, distance from basking site, etc. We use a T5 fixture the length of the top of the enclosure on our chameleon cages.
Hello, I have a specific question. I have a 2 years old hermanni-boatgeri tortoise. I was going to use the Exo Terra Solar Glo 80W - last year I used a ReptiZoo Solar Sun 125W but It seemed like it was too strong, and from what you tell me it might have too much penetration (its terrarium is 33"x12", I made it myself watching other people's ideas here on RUclips) . Now, aside from the fact that I ordered these off of Amazon and they both arrived with a part of the internal coil hanging & that they wouldn't turn on on my ceramic socket (the ReptiZoo still lights up perfectly so I don't think it's my socket, these only turn on on the top with a slight blue-colored light, but the rest of the lamp remains off), do you think they might still be too strong for a tortoise? Suggestions are very welcome, around here where I live shops don't even have mercury vapor bulbs and don't treat reptiles.... I just wanna make sure that the little guy is as good as it could be. Thank you very much!
I need an UVB light for my red eared slider. Would you recommended a 3 in one like solar glo or a mental halide lamp? Does the metal halide provide enough heat so I don't have to use an additional heat source?
If i have a beardie in a 120 gallon tank and he basks on top and hes pretty close to the mercury bulb all in one u said its up to 3 feet what if hes basking but the bulb is 5 inches away from him? Do i change it ??or put moreheat in the tank? I also use in all in one mercury bulb for my russian tortoise and hes 12 inches from the bulb and is basking by it is that good or is he too close too it meaning i have to change it or hang it up is becasue im trying to make sure he stays warm but i dont want alot of uvb penetration either
I'm still not sure which strength/brand uvb bulbs to use for my aquatic turtles. In one tank the basking area is 8-10 inches away from the light fixture with a hatchling slider in it. In another tank the basking area is 7 inches with a hatchling cooter and in the third tank the basking area is 9 inches from the light fixture, with a hatchling musk turtle. These distances are perfect for the temperature and I am using a dual 5.5 dome reflective fixture. Thank you in advance for your help!
Hey Matt, does UVB penetrate water (talking about aquarium, so not deep, no mesh). Cause if it does, unlike glass, my RES can absorb it under water as well. And i need only heat bulb for basking spot. meanwhile i place a UVB over the water portion, unobstructed with mesh or glass.
Hi there I'm totally confused LOL. I would like to install it inside UVB can you recommend one or I have a 40 gallon tank with the screen can you just tell me which one to buy LOL this is just still too confusing for me
It depends a little on the animal and the setup. If you're using one of the mercury vapor bulbs, the UVB penetration from those bulbs is adequate enough you'll still reach appropriate UVB levels even with a screen in the way. If you've decide to use tube lighting with your animal, go for the T5 High Output fixture if you need it to be able to penetrate the screen. If you go for a T8, they're weaker and perhaps best installed inside the enclosure.

Wow! Thank you Matt for a great lesson on lighting. I was so confused with all the bulb types out there and what exactly I would need. Your clear and concise video really helped. Nice looking store too. Thanks and take care.
The best UVB video on RUclips ❤
We're so glad you found it helpful! Did you have any questions about UVB that our video didn't address?
Best vidio I've seen so far. Thanks.
I just called this place and the lady was amazing!!! I wish I lived so much closer but its not that far. She told me about lighting and offered to help me when I came in. Awesome place!!!
We appreciate the kind words, and we're glad we were able to help you out!
Dude this video is top notch. Really, awesome job explaining everything and showing the different products, without any fluff or filler. Super interesting!
Great educational video. However I have a question is it necessary for the bearded dragon to have UVA and UVB in it's enclosure?
It's absolutely necessary. In the wild, they'd have exposure to the sun, that allows them to regulate bodily functions and Vitamin D synthesis. We have to do our best to replicate it in captivity. Without it, they will eventually stop eating, suffer from metabolic bone disease as they can no longer absorb calcium, and eventually, death. Reptiles, for the most part, are essentially solar powered.
I'm new to this reptile world especially bearded dragon and planning to get one soon, and i Can't find any better videos about uv lights thn yours ! This is by far the best explanation about uv lights for reptile , thank you so much !
Thank you for a straightforward, simple way of understanding all this. Now, I know that UVB lights can be checked with an expensive meter to see if they're still making UVB, but do you by chance know of a type of rock or everyday household item that we can hold under the flouresence UVB bulb to see if it's still emitting UVB rays? I'm googling and can't find anything yet-- but surely there is! To maybe use instead of a pricey meter that would let us check from home?
Unfortunately any of the objects marketed as reading UVB like the cards or stickers, etc. on a color scale are not very accurate. They may read there is still UVB output but it may be at a much lower (or even higher) level than what your reptile requires. The only way to get an accurate measurement on UVB bulbs is with a Solarmeter.
The meters can often quickly pay for themselves however, as you can replace bulbs as needed and not just on a 6-12 month schedule.
@@TyeDyedIguana Great! Thank you for your reply!
FINALLY a video that clearly explains all the different UVB bulbs! Thank you!!
Ok this was probably the best video I’ve seen on the difference of UBV bulbs! I got my bearded dragon that’s my first reptile about 6 months ago and tbh I’m learning as I go!
Great video! Thank you for explaining this. Now I understand why bulb I need to get and why.
Matt - I have to thank you so much for posting/making this video! It literally saved my Chams life! I am new to reptile keeping and have always wanted a veiled chameleon. I recognize they are not recommended as a first reptile so I did so much research and thought I was well informed, educated and prepared to raise one. I bought one from a local pet store (which I know is always advised against doing) but this particular one called to me. She is such a sweet girl. About a month into having her I noticed one day she was super shaky and weak while trying to walk. I immediately started researching MBD and your video popped up when I was researching lighting. I went out and purchased the mercury vapor bulb and made some other changes to her enclosure and she is improving nicely in a weeks time!! I really didnt understand the difference and how much different they actually are AND since I changed those things she has been bright green!! I am so thankful to you for providing this (and in layman's terms) easy to understand and vital information! Thank you from me and Zuri!! 🦎❤
How is your chameleon doing now?
@@11SEXMACHINE She is doing beautifully!! Thanks for asking. I just upgraded her enclosure so I think she will be happy about that once I get it all set up. I have a question maybe you can answer. She always wants to come out of her enclosure to just sit on my hand (or my head ha ha ha). How long is it safe to keep her out? I cant seem to find that info anywhere?
She actually laid her first clutch of 40 (infertile) eggs today! Pretty cool experience. Any advice for her after laying eggs??
I have a question I’m currently using a solar glo uvb bulb that provides heat,uvb, and uva is that fine for my bearded dragon in a 40 gallon tank?
It can vary a little bit with your room temperature, etc, but we find using the 160 watt Solar Glo on our 40 gallon tanks tends to be perfect for our dragons. You might need to raise or lower the bulb or the basking area to get the temperature exactly where you need it.
Lots of bearded dragon owners have been gravitating towards using linear T5 UVB bulbs and separate heat as well, since that way you can offer an area with both, an area with just UVB, and an area with no lighting.
@@TyeDyedIguana alright thank u so much
I’ve watched a lot of videos tonight. This one helped me to understand which items to order the best. Thank you guys. 🙏
Best explanation ever. Thanks for making the video. Keep up the good work!
I've seen a lot of videos about reptile lighting and this one is on point. I've had my baby beardie for two days. I purchased a 20 gal tank kit for now. I was clueless about what type bulbs to get for a bearded dragon nor did I understand what the 5.0 meant. Thanks, your video was very helpful and informative
so you covered how far the UVB pen's but is getting it to close bad? Im doing a 4x2x2 with a Uromastyx and I am having issues finding out the best way to go with UVB bulbs go and Basking. I was looking into the Vapor mercury since I can get heat and UVB but I need like 115-120f on the basking
You just add another heat bulb next to the MVB, like a halogen. Placing a UVB bulb closer to the animal than the recommended range can damage your reptiles eyes and cause severe burns. It's the wavelength that is primarily responsible for sunburns.
@@TyeDyedIguana Thanks for the fast response. Im looking at doing a ARCADIA PROT5 14% UVB 36" in the 4x2x2 and a basking bulb would that be a better option not factoring price? With that setup would you put the UVB more center since its a 36" or opposite the basking?
@@brmcdonald68s1 If you're going to use a linear UVB bulb, you'll want it to overlap the basking area. The idea is that you're mimicking a sun patch for them to bask in, so you want an area where they can get their heat and UV in one spot. The opposite end should have no light, so they have a cooler, darker area if they'd prefer. Either set up will work, but you'll probably still need the power of two basking bulbs with the linear light.
Thanks very helpful understanding on how each bulb functions
Thank you for this informative video!!
I am grateful for the explanations.
The babies are friggin precious. They will grow so quickly...
you said that the "solar glo" mercury vapor bulbs have three feet of penetration, yet you also said that they are perfect for a bearded dragon in a 2 foot tall enclosure. Wouldn't they be too much for a 2 foot enclosure then? I guess it depends on how high above the lid you mount the light? It seems like it'd be to much for setting right on top of the lid, or inside the tank @4:50
These bulbs do have 3ft of penetration, but at 3ft, you'll have less UVB output than at 2ft at the basking spot. The 3ft mark is the maximum amount of distance from the basking spot before you basically don't have any UVB benefit. The distance depends on the animal you're keeping. At 3ft, it may be great for a tropical animal, but at 2ft, it's better for a desert animal.
Man this is a great vid that answered my questions
That's great! We're glad you found it helpful.
Clear, through, effective.
This in an amazing video 🙏 ty
Matt, SO I just received a 75GAL tank/stand/canopy W/LED lights combo from my Wife as an early X-Mas present. I'm planning on building an acrylic ATBA W/solvent welded seams, a large ramp, and a large piece of dark slate for my future turtles to bask on. I already know that I want to use a mercury vapor bulb. I also know that I want to make my ATBA roughly 1FT high, and will most likely use a ceramic socket clip on light fixture, clipped to the top of the ATBA, putting my bulb roughly a foot from my future turtles. I'll be getting a male Black-Knobbed Map and a male Pearl River Map hatchling. Knowing all of this, what wattage of mercury vapor bulb should I use?
Depending on the room temperature, you'd be looking at an 80 watt, possibly 100. It may require a little trial and error.
Keep in mind that anytime you're cohabitating animals, you'll need to watch for competitive or territorial behavior.
@@TyeDyedIguana Thank you for the quick and knowledgeable response. Your videos on lighting are must see "TV" for any reptile enthusiast!
Doesn't all of those bulbs have glass? If yes, how do they produce uvb?
Not all glass is the same! There are lots of different types and they filter UV differently. The glass commonly used in homes, for example, filters too much to be of benefit to our reptiles. UVB bulbs are designed with a special type that allows UV to pass through.
@@TyeDyedIguana what if i get an ordinary metal halide bulb and remove the outerr glass? Will that be the same as an uvb lamp since the interior ark bulb is made of quartz and it doesnt block uv
@@Anktual We don't recommend using anything other than UVB reptile bulbs manufactured by companies like Zoo Med or Exo Terra. These are manufactured specifically for levels of UVB that are appropriate for the reptile's health. Modified or off-brand bulbs are a risk for dangerous levels of UV or not enough. We've seen instances of burns, eye damage, or metabolic bone disease from using inappropriate bulbs.
@TyeDyedIguana sorry i forgot to mention i want to use it on supermarket mushroms to make vitamin d.
Thank you for explaining this.
For the solar glow from exoterra, could you please please please please please explain which wattage Mercury bulb I should buy depending on the height of my tortoise table?!
We use the 160w bulbs on all our tortoises here. You may need to raise or lower the bulb to reach the correct temperatures on your tortoise's basking spot, or in the case of a larger enclosure, use more than one bulb.
Tye-Dyed Iguana thank you so much! I was already wanting to get a solar glo and this video sold me☺️while I’m here I should ask, what’s the minimum size tortoise table for a fully grown Russian tortoise and what’s the best substrate for them?
We do have a video that explains more in depth on their care, but we consider the minimum to be 36 x 18 x 16, or a 40 gallon. In the case of a tortoise table, you have the freedom of a custom made enclosure, so we recommend making it bigger if you can! Fir bark, coconut fiber, or a mix of peat moss or sand can be used as a substrate.
Tye-Dyed Iguana thanks again!
For a bearded dragon on a 40 gallon tank, uvb on top of tank, would the T5 work better than the t8 ?
T5's are becoming the new normal when it comes to lighting. They're stronger and penetrate better than the T8's. T8's are getting harder and harder to find. We still sell the bulbs, but we do not offer the T8 fixtures.
Very informative that's a great video right there thanks Matt
What about led bulbs? Do they produce efficient uvb?😊
Unfortunately led bulbs do not emit any uvb
Are any of these strictly UVB without UVA?
Pretty much any UVB bulb (like the compact or tube lights) that isn't a mercury vapor bulb is UVB only, and would require a separate bulb if you need heat.
@@TyeDyedIguana Would you point me in the direction of a compact or tube light that is UVB only please? Thank you in advance.
@@TyeDyedIguana Everything I've found online is a UVB + UVA combination. I'd like a strictly UVB bulb.
All of our available bulbs are here : thetyedyediguana.com/light-bulbs/uvb-bulbs/
Anything on those pages that isn't a mercury vapor bulb is UVB only. The size and output of your UVB bulb will depend on your enclosure and what type of animal you have.
@@TyeDyedIguana There is discrepancy in your claim:
The UV region covers the wavelength range 100-400 nm and is divided into three bands:
UVA (315-400 nm)
UVB (280-315 nm)
UVC (100-280 nm).
www.who.int/news-room/q-a-detail/radiation-ultraviolet-(uv)
Here is the bulb manufacturer spectrum output for the "New Spectrum! Former Repti Glo 5.0":
www.exo-terra.com/en/products/reptile_uvb100.php
The graph clearly shows higher power output in the UVA range than in the UVB range.
thank you for your very complete video. What splash proof UVB light bulb would you recommend for a turtle?
We don't have anything specifically splash proof for UVB, but most people go for either the florescent tube style or compact. Tube lighting will give you better coverage. You'll just need to be careful with the bulb, but generally the hotter the bulb runs, the more susceptible it is to shattering from water. UVB bulbs don't produce much heat.
@@TyeDyedIguana thank you i apreciarte your guidance on this matter.
You can be a great teacher, wow !
So for a 20 gal tank with a screen what bulb should I use for a bearded dragon juvie
Excellent video but I still need help. I built a tank for my bearded dragon that is 41"L x 20"D x 18"H and I bought a T5 HO 36" Reptisun Hood and I want to install it inside the tank, is this the correct size hood and also should I use the 5.0 or the 10.0? Thank you so much for your help.
Typically for a bearded dragon, you want the length of the UVB to go across about 1/2 to 2/3rds of the length of the enclosure. The 10.0 would be right for a desert animal, the 5.0 is more suitable for tropical animals.
@@TyeDyedIguana Thank you!😀
I have a 5 x 2 x 2 large enclosure for an Australian Water Dragon. I only need a 95 degree hot spot...rest of the tank about 80. I need a combo UVB/heat bulb. How much wattage?
It's going to depend on quite a few factors, so you may have to try a few different wattages or setups to get it right. It may change whether or not the bulb is installed inside the enclosure, or sitting on the top through mesh, the distance between the bulb and the basking area, the ambient temperatures inside your house...you get the idea. So I would say start with a 160w if it's sitting on mesh or away from the basking spot. If it's mounted closer and inside the enclosure, there's a chance it'll be too hot, so you can always bump it down to a 100w if it is.
@@TyeDyedIguana - I think 100 might be enough. There is a screen the light has to go through but the cage is set up in a way that the light is right over top of the basking spot and not a huge distance. I had an 85 Watt Powersun bulb I had from a while ago and the basking spot was about at 90. Since they only need a 95 degree basking spot and the rest at 80, the 100 watt Powersun might be enough. Since it is a large tank, I might put some normal heat bulb on other side just to keep temps up high in enclosure as a hole. It is a 5 x 2 x 2 Showcase Cage.
question.. so between the t5 & t8 varieties do you recommend one over the other? i keep hearing that the t5 doesn't flicker so therefore its better.. im building a 4'x2'x2' enclosure for my beardie & will be mounting im guessing a 34" (since the bulbs come in weird lengths) im worried that the t5 may be too small for such a large enclosure.. what would you recommend? any input would be greatly appreciated! originally i was just going to put a mvb for day & a ceramic heat emitter for night.. i have since decided the tube uvb would be a better route & to just keep my house above 65°[sigh] im just struggling on deciding which fixture to buy for the uvb. its going to be mounted inside the enclosure. if anyone could chime in it would be appreciated.
thanks!
For a desert animal, you may have better luck with the T5. They are higher output and the stronger bulb out of the two, and being that it is smaller along with the better output, gives you more flexibility.
Tye-Dyed Iguana thank you so much! i was so confused
Great video!!! Very well explained!! Thank you!
Thanks for the info. Very helpful.
Great video man!! Been looking to see which bulb is best for my bearded dragon in a 40 gallon tank. Only for now I know he needs a much bigger tank to be content.
Great Job Matt!!!!!! Great facts! Watching this video of Matt being a reptile genius literally just made my day, just fell and busted my lip open on ice in my back yard😂
-Noah
So from the screen to the floor of my leopard gecko s tank is 12 inches....
Would i go with a 5.0?? Seems possible that a 10.0 would be too much.... Hoping i get an answer
A 5.0 would be appropriate, a 10.0 too much. Leopard geckos are crepuscular, meaning most of their activity is at dawn and dusk. They wouldn't be out in full desert sun.
@@TyeDyedIguana Thank you for answering.... 🙂
I'm building a paludarium that's 3 ft tall for a rhino rat snake. Trying to figure out which lights (if more than one) for the plants as well as heating. Any suggestions?
Typically plants will do better with an addition of an LED strip light - though it's important not to overwhelm the animal with lights that are too bright or unnaturally colored like the purple grow lights. Some reptile UVB lighting fixtures also come with LED lights.
@@TyeDyedIguana thanks for the response I'll look into it 👍
@@TyeDyedIguana went with the Arcadia jungle dawn for the plants. I'm a little confused with the uvb, was gonna get the shade dweller for uvb...would I still need a heat lamp. This has been a big learning process but i wanna nail it.
@@spyrotherhino Yes, you would still need a heat source. A standard UVB tube does not emit enough heat for basking.
Lots of solid information in this video. Well done!
It actually helped me alot! Thx
Great video, very informative.
Can i used the zilla t8 on my 36" x 18" x 18" 40gallons tank for my leopard geckos? & one of exo terra 36" x 18" x 12" for a bioactive for a red eye crocodile skin?
Yes. For both of these animals, you can use a low strength linear UVB light during the daytime. You want bulbs marketed for tropical or shade dwelling species.
@@TyeDyedIguana thank you so much i really i appreciate it! I been made some updates to my tanks and I'll put them in a metal shelves but i need to change all my light's to low profile i have i few already from zilla the single one with a bulb of 6w for the small ones, 10 & 20 gallons but i need to change the lights for the big one and i just want to make sure the i do the best for them. Thank so much!
Thank you, very thorough.
hey matt i have 2 juvi green iguanas under a year old. they are housed (temporary )in a 35gallon hex tank with crape myrtle branches running across diagonally to give them a high place to perch ,
we also have a metal screen top cover . at the moment i have a cheap uv/60 watt sitting on the mesh along with a heat emitter( i leave on 24/7 for temp) the depth is 22" top to bottom should i shoot for the upper half of the enclosure for depth penetration (ie bake them with a 5.0 or mercury vapor ? i dont want to over expose them or should i get the 10.0 and get to the bottom of the tank as well. thanks
Usually when we measure for target heat and UVB, we measure from wherever they have their basking spot set up. So if the basking spot, like a branch, is up from the ground, that's where you'll make sure you would hit your ideal temperatures and UVB readings.
I planning on getting a 4x2x2 zen habitat enclosure. So, the mvb bulb be better?
So which would you recommend for a California King snake in a 20 gallon terrium
It's thought that snakes do not require UVB as the majority of them are nocturnal. They are usually only supplied with a heat source.
However, lots of people are of the thought that adding low levels of UVB during the day for even nocturnal animals can be beneficial. Quite a few of them can be seen during the day basking. If you would like to add a UVB light to your snake's enclosure, we recommend a lower output bulb like a 5.0.
Tye-Dyed Iguana okay yeah cuz I heard that and I would want the best setup for my snake I can make when I get one. Thanks
So we can’t put the uvb light over glass?
No. Most glass blocks most to all UVB light. UVB bulbs are designed to go over mesh screen, which will block a percentage of UVB, but not all, or installed inside the enclosure depending on the set up.
You just confirmed my worries I bought my baby corn snake at a chain store in which I work the salon and for anzoomed 25 gallon reptihabitat I believe 30 x 16 x 13 with screen blue daylight 100 watt for heat and when I insisted it needed uvb a thrive brand uvb 5.0 I need to double check but I think 25 watt the micro bulb things and I was finding the blue daylight didn’t give it any kind of a gradient and even at 100 watt wouldn’t get me an 85-90 basking and not much different from the cool to hot side so I went to a 75 watt reptibasking light for heat and basking seems o fix the hot spot and gradient but I’ve been worried about the uvb btw the uvb and basking are in a dual fixture by thrive and I remember having a beardie with a 4 x 2 x2 with a t8 built into the tank around the middle completely away from the heat and basking so I was trying to figure if it’s safe being side by side and using the compact or if I needed a t8 5.0 moved over a bit and this is clear with my screen I need to upgrade to a 10.0 wether in the same spot compact or t8 and moved over this may explain which my snake while seemingly healthy great eater and handles well stays hydrated is always under its hide and water with this info would u recommend sticking with the compact and at what wattage just switching to a 10.0 or upping to the reprising t 8 10.0 18 inch I’ve been looking at prior to this video I was looking at the reptisin 18 inch 5.0 but I think ur video made it clear with my screen top 16 inch to floor 5.0 simply does not cut it
Corn snakes do not need much UVB, they bask more cryptically and the 10.0 is intended for desert animals. Stick with a 5.0 bulb or something similar labeled as either tropical or shade dweller.
Love this. NEVER EVER heard bulb science broken down like this before. 🫡
Thank you so much! We're happy to hear you found this helpful! What kind of reptiles do you keep yourself? 🐍🦎🐢
Excellent video, thank you.
Excellent video...👍
Awesome video. Great information. Very informative. Keep up the great work.👍👍
Any more videos of Matt providing information? He explained UVB lighting very well.
He did another one for us on heat bulbs more recently. Here's the link for you. ruclips.net/video/Hxt_tmumKJg/видео.html
For my 48 x 18 x 18 bearded dragon tank will the reptisun t5 ho fixture with a 10.0 tube provide proper uvb when placed on top (screen lid)and what should the length be I’ve gotten mixed advice some say the full length and others say 2/3s the length ?
Yes, for a bearded dragon, the 10.0 tube is recommended. Make sure you have a raised basking spot for him as a mesh screen will dramatically cut down on your UVB output. On our enclosures where we use UVB tubes, we do the full length of the tank. Not only can they get the benefit no matter where they are in the enclosure, it looks a little nicer.
Which one is the most adecuate for humans with Vit D defficiency?
Thnaks for the video!
None of our bulbs have been rated or tested for use on humans, only reptiles. We can't vouch for either the efficiency or safety of their use on humans. We recommend consulting with a medical professional in this case.
What can I use for a baby turtle ? I had got a flukers clamp lamp for heating but I need a uvb light but some say to get both uva and uvb someone help please 😭 I have a screen on my turtle aquarium I was thinking of getting a outside basking area too
UVB bulbs output both UVA and UVB. You need a heat bulb and a UVB bulb. Since aquatic turtle basking spots are usually pretty close to the light, you can use either a compact UVB bulb or if it's a little further away, a T5HO fixture. You'll want to get UVB bulbs that are labeled as tropical, generally. That'll be a 5.0 or 5%-6% bulb, depending on the brand.
Extremely informational, thank you kindly sir.
can i use other fixture for T5
The reptile branded T5 fixtures are what we recommend. They are built with reflectors that help to strengthen the amount of light that is projected downwards toward the enclosure. The estimated output the companies put on the boxes are based on using those fixtures and they may not be efficient enough using an off-brand fixture.
I have a 100w MVB for my juvenile beardie who is in a 40g breeder with one of those double domed fixture. But it definitely didnt give a warm enough basking spot so i put a basking bulb in the other socket.
No, a 100 watt MVB would not produce enough heat for an enclosure that size. We use a 160 watt bulb with each of our 40 breeder enclosures.
So for a tank that is 5 ft long and 3ft tall… what would you suggest?
A lot of that is going to depend on what species you're keeping and the height from your light to your basking spot.
Give this guy a raise
Well he's the shop owner here, so - that's up to him!
A price then😂
I’m a first time owner of a bearded dragon he kind of just got landed on me so I plan on buying him a bigger tank but I’m not sure if I should get 2 UVB lights and 2 basking for 120 gal tank
That would all depend on the set-up of your enclosure, and the bulbs in question. We find that one long linear UVB, can suffice. For larger tanks needing extra heat, we do find that an additional low wattage bulb or ceramic heat emitter can be beneficial, attaching your heat sources to a thermostat is the best way to ensure consistent and proper heating 😊💡
I have a red foot tortoise in a low profile reptile tank with screen. What do you recommend?
We use mercury vapor bulbs with a lot of success with our tortoises, but we can't make a suggestion without an idea of how far the bulb would be from the basking spot.
So you’re saying that I can use a powersun bulb without needing a fluorescent t5 thing?
Any of the mercury vapor bulbs will provide UVB for a basking spot. You do not need an extra bulb for UVB unless you want more coverage across the enclosure.
Whats bulbs would u recommend for a 40-50 gallon. For UVB and heat
It would entirely depend on what species you're planning on keeping.
Also I made a homemade fish filter. I used a submersible pump and I'm forcing water through the INSIDE of the carbon filter. I put an aerator directly underneath it stuck to the glass and the spin of the pump wheel...is hyper oxygenating the water. Fun little breeder and store owner tips tricks hints and pointers. I'm making a pvc grid with a tank liner over the top of it then up the corner of the tank to a halo, that's been Bernoullied. So the holes near the exhaust of the water tube at the top of the tank are smaller and gradually get larger to spread the pressure and output of each outputhole the same g.p.h. all the way around the tankhalo. Really only aquaculturiats use stuff like this but I'm a modfreak. I believe strongly in products that function PROPERLY. Simile, gracefully, like 3M. ;) and if I ever didn't thank you. Thank you.
Thank you so much! That made perfect sense.
do they have a datasheet with the spectrum?
i am looking for a light bulb that delivers a lot of power in the wave length of 295-320nm because that is the wavelength where the body produces the most vitamin d
We do not have a concise data sheet for every single bulb we have available. What we can say is that providing the bulb recommended for your animal and a basking spot at the proper distance will give them adequate UVB levels for D3 production. Any data that the manufacturers have provided about wavelengths is usually available on their individual websites.
Ibhave a juvinile eastern hermanns tortoise..what setup would you recommend?
Young Hermann’s Tortoises must have a minimum cage size of 36” Long x 18” Deep X 16” High. An adult should be housed in a 6’ long x 3’ deep enclosure. An ambient temperature gradient of 75-85F and a hotspot of 95F is ideal, with a UVB source emitting between 10-12% UVB. We strongly encourage linear UVB bulbs, such as a T5 or T8 whenever possible, as they cover the most space and seem to be most efficient. Mercury vapor bulbs are another option that emits heat and UVB in one source. Specific lightbulb types, to achieve this, can vary depending on your set-up size and dimensions. As larger set-ups may need a stronger wattage to achieve desired readings. What kind of enclosure do you have for your tortoise?
Very good video! Well detailed and very understandable!
What lighting would you use on a zen habitat 4'x2'×2'? Does the tube uvb light need to be below the screen and which one T5 or T8?
It depends on the sort of animal you're going for, but if you're wanting stronger UVB the T5 is the way to go. If you can mount the lighting on the other side of the screen - go for it. Screens block out quite a bit of the UVB but sometimes it just isn't possible to set it up on the inside with many premade enclosures on the market. The result is then the basking spot needs to be closer to the light if the screen is between the animal and the light.
@@TyeDyedIguana It will be for a bearded dragon. So I need to place both UVB T5 and the solar glo 160 W under the screen. I do believe it has a place I can hang them.
So if ur tank is 17 in. From the light is it best to use the 15.0 that supports 22 in. Considering the screen takes away a few inch's/uvb rays ??
Does a dimmer affect my uvb bulb a lot?
What kind of UVB bulb are you trying to use a dimmer on? In most cases a dimmer will not work with them and can potentially burn your bulb out.
@@TyeDyedIguana ty I will not use a dimmer
So for my tank I have a 40 gallon zoo med tank and I was wondering if I should use the UVB stick or if I should use the bulb that came in the kit (it’s in a dome attached the the heat bulb and it’s the 40 gallon zoo med kit if you know what that is). Also when I turn on the light it shows light in the whole tank.. so should I keep this or get the stick? Stay safe everyone!
The long UVB bulbs are preferred by many keepers as it allows the animal to get UVB in more areas than the basking spot. The compact bulbs are more limited in their coverage area but are good for smaller tanks.
Thank you so much for this information!
What do you recommend on 18 by 18 by 30 enclosure for a 2 month chameleon
The strength will depend on the species and how the enclosure is set up, amount of foliage, distance from basking site, etc. We use a T5 fixture the length of the top of the enclosure on our chameleon cages.
Fantastic. Honestly, everything you need to know and nothing more.
What UVB strength works best for Green Anoles?
A 5.0 bulb or anything listed as tropical will be what you're looking for when it comes to anoles.
Hello, I have a specific question. I have a 2 years old hermanni-boatgeri tortoise. I was going to use the Exo Terra Solar Glo 80W - last year I used a ReptiZoo Solar Sun 125W but It seemed like it was too strong, and from what you tell me it might have too much penetration (its terrarium is 33"x12", I made it myself watching other people's ideas here on RUclips) . Now, aside from the fact that I ordered these off of Amazon and they both arrived with a part of the internal coil hanging & that they wouldn't turn on on my ceramic socket (the ReptiZoo still lights up perfectly so I don't think it's my socket, these only turn on on the top with a slight blue-colored light, but the rest of the lamp remains off), do you think they might still be too strong for a tortoise?
Suggestions are very welcome, around here where I live shops don't even have mercury vapor bulbs and don't treat reptiles.... I just wanna make sure that the little guy is as good as it could be.
Thank you very much!
I need an UVB light for my red eared slider. Would you recommended a 3 in one like solar glo or a mental halide lamp?
Does the metal halide provide enough heat so I don't have to use an additional heat source?
If i have a beardie in a 120 gallon tank and he basks on top and hes pretty close to the mercury bulb all in one u said its up to 3 feet what if hes basking but the bulb is 5 inches away from him? Do i change it ??or put moreheat in the tank? I also use in all in one mercury bulb for my russian tortoise and hes 12 inches from the bulb and is basking by it is that good or is he too close too it meaning i have to change it or hang it up is becasue im trying to make sure he stays warm but i dont want alot of uvb penetration either
excellent info thanks!
I'm still not sure which strength/brand uvb bulbs to use for my aquatic turtles. In one tank the basking area is 8-10 inches away from the light fixture with a hatchling slider in it. In another tank the basking area is 7 inches with a hatchling cooter and in the third tank the basking area is 9 inches from the light fixture, with a hatchling musk turtle. These distances are perfect for the temperature and I am using a dual 5.5 dome reflective fixture. Thank you in advance for your help!
Hey Matt, does UVB penetrate water (talking about aquarium, so not deep, no mesh). Cause if it does, unlike glass, my RES can absorb it under water as well. And i need only heat bulb for basking spot. meanwhile i place a UVB over the water portion, unobstructed with mesh or glass.
Hi there I'm totally confused LOL. I would like to install it inside UVB can you recommend one or I have a 40 gallon tank with the screen can you just tell me which one to buy LOL this is just still too confusing for me
It depends a little on the animal and the setup. If you're using one of the mercury vapor bulbs, the UVB penetration from those bulbs is adequate enough you'll still reach appropriate UVB levels even with a screen in the way. If you've decide to use tube lighting with your animal, go for the T5 High Output fixture if you need it to be able to penetrate the screen. If you go for a T8, they're weaker and perhaps best installed inside the enclosure.
I have a juvenile dragon in a 20 gal what is my best option cause I don’t feel like mine is hot enough
