Is this video still accurate? is HPS still more efficient than LEDs. If they are, then why do I keep hearing that the high cost of LED fixtures can be offset by the lower cost of ownership. I assumed that mean it will use less electricity. Is thus only because the bulbs last longer?
+Everest Fernandez You talk about efficiency for incandecent, floresent, MH, HPS, CFL, even LED!!! (holy guacamole say that in one breath!) But how efficient is CMH? (or LEC) Please please, tell me! tell me! tell me! tell me!
Ive a 600 watt hps lamp. Been using it for around 6 months, I've started to notice that the light has gotten alot whiter than the orange glow it used to give off. Is it time to swith bulbs? Im assuming yes but would love several opinions ☮️🇯🇲❤️
They should last about 5 years (well, going based off street lighting times, about 8 hours a day), but if yours is on all day, it should still last a couple years. Probably a cheap or defective bulb. Although I'm not sure, I've never heard of one getting whiter with age, or malfunctioning. They usually stay orange, if anything they get deeper orange, and cycle until you do something about it and change it.
Good question Arsen! It obviously depends on your utility supplier's charges. I recommend running your grow lights during the nighttime-not only will temperatures be easier to control in your indoor garden, but some electricity companies charge less for nighttime usage. As an example, if you were running a 1000W HPS light for 12 hours per day and your electricity supplier charged $0.12 per kilowatt hour, then over a 30 day period your HPS grow light would've been running for 360 hours. 360 x 0.12 = $43.20
***** Thanks FallenAngel. Growing the plants that you love to grow, 365 days of the year, in the privacy and comfort of your own home .... well, it's got to be one of the most rewarding hobbies out there. I guess that's why I feel such an affinity with other growers. Indoor gardening is a wonderful world-a veritable sanctuary for me!
how do they to change the spectrum, each company uses a slightly different spectrum, is the ark tube coated with phosphor like a fluorescent to give different spectrums, i am wondering how to make a hps light with just the red or blue spectrum
+Tony Boroni Hi Tony, you're right, mercury does produce UV light however the amount of mercury inside an HPS lamp is so minuscule that the amount of UV produced is insignificant. You've also got to consider that any UV is effectively filtered out by the glass of the lamp itself further reducing the UV output to almost nothing. One of the main reasons lamp manufacturers use mercury is to regulate the operating voltage of the lamp. I'm also going to stick my neck out and say that to make an HPS lamp to focus just on 650 or 660 nanometers, would be extremely difficult / nigh impossible due to the laws of physics and the chemistry needed to operate the light.
In general, they are very good. HPS is a mature technology and a lot of work has gone into optimising the spectrum for horticulture. The blue-enhanced HPS are excellent for indoor growing.
Mike Lattimer Hi Matt. Thanks for your question. The lamp requires 4000 - 5000 volts to ignite and then, once the arc stream is stable, it runs at 250 volts. Does that answer your question okay? Please consider subbing my channel. Thanks! Everest.
Everest Fernandez Everest Iam trying to make a flipper. I have four 220 volt ballast and am trying to use relays on the secondary side of ballast to send the current to room #1 12 hours then room #2 for the next 12 . My lamps are not igniting and I cant figure out why. Will a standard ice cube 120 volt AC relay work to carry the secondary voltage to the bulbs? I thought the coil inside of it might be interfering with the pulse voltage on start up.
Mike Lattimer Hi Mike. A standard ‘ice cube’ relay doesn’t function well in this type of application due to the switching voltages involved. A better solution is a definite purpose contactor like this one from Deltrol Controls. It is their 900 series relay. www.deltrol-controls.com/sites/default/files/imagecache/product_index_image/images/familyimages/img-9001cdpdt.jpg These are power relays that are intended to work in both the NC (Normally Closed) and NO (Normally Open) positions. This is accomplished by utilizing a ‘trigger cordset’ that opens and closes the relay contacts using voltage input. In the NC position bank #1 of lights fires, in the NO position bank #2 fires. This is the technology used today by LightSpeed flippers and Powerbox flippers. The most simple approach would be to purchase one of the “pre-built” flippers and use that in their application. However, if you want to build it yourself then you may want to consider using the Deltrol Power Relay to accomplish this task.
Mike Lattimer Yes and yes. But, to be honest, the only safe advice I would give here is to check out something like the Flipbox by Powerbox ( www.powerboxinc.com/flipbox.html ) and use that or reverse engineer if you have the know-how. I don't want to sound like your dad but be careful! I presume you are a qualified electrician. If not, buy it and get it professionally installed. Safety first. Peace and happy growing. Everest.
Anyone out there run a 400 watt HPS bulb with a 600 watt digital ballast at 600 watts? I am interested in trying this but would like to know if it is a dead end fire starter? If the ballast can handle it that is good . If the 400 watt bulb running 600+ watts only last 100 hours that is also okay. What is not okay is flame roasting problems. JFYI I am not growing anything but old
You should only run an HPS lamp on a ballast specifically for the wattage of your lamp. It is dangerous to run an HPS lamp on a ballast for a different lamp wattage or lamp type.
+Yofatboy124 also why cant they make them with more of the red spetrum or blue, also they could make a round tube and put electro magnets on them and it would last longer, they use the technologies with fluros and there like 1000 dollars a light way over priced.
Vasa Rastkov Hi Vasa. I'm very interested to try induction lighting and will do my best to get my hands on a fixture this year. You can be sure that, once I do, I will make a video all about induction lighting. Same for LEDs. Same for Plasma.

the other guys to watch are greengenes and growmau5 they've done several vids on it . And greengenes I belief has just designed and now sells plant lights with the new cree cxb chips . I design build and test . my own lights . I'm testing fresnal optics at no , and getting good results
so basically...LED's are just NOT good enough for indoor grow if you're serious about the crops. no wonder professional hydroponic stores don't really market LEDs. Only amazon does.
My only argument here is LED's produce less heat and have a predicted longer life-span. Yeah they might not be the "most" efficient but they are more practical for long term investment. Quality LEDs can last up to 50K hours where HPS fall in the ballpark of 12-24K. But yes, they aren't as efficient and don't have tons of spread like a traditional bulb would. Pro's & Con's
Jesse Matz Hey Jesse. I just got hold of a new generation LED fixture-200W-quite a chunky beast! Big fans and heat syncs at the back. I'd argue that it produces more heat, watt for watt, than an HPS-hence the lower efficiency rating (the rest goes to heat) - but I will try and figure out a half-decent practical test to demonstrate it for real! :)
HPS is still the perfect out of the box light today. See the recent interview on migro. ruclips.net/video/X1O3OD-dI20/видео.html and LED today is only slightly more efficient but lacks intensity.
thanks for the reply . I believe we worked it out to be about 50% , others claim 55% if my very poor memory serves me well . I use 3500k and a large 78mm *25mm lense . The photons it produces are incredible ,and l can turn it down if needed . I love the tech of it all ,but its crazy how quickly its advanced in the the last 4 years that I came to be enlightened by them
Meh, 30% LED vs 40% HPS isn't much of a difference, especially when you consider your electricity bill and getting a silly converter. I'll stick to LED and my bounty aerogarden ;)
LED has just not evolved enough for me to give up what it produces. to be competitive enough or economical enough to repleace HPS. Also LEC holds more promise at this point to surpass LED
A major problem with hps lamps is the propensity to fail explosively, spraying the growroom with burning sodium and mercury vapor, and poisoning your home while burning it down. So a good, approved, and sealed light fixture is of paramount importance.
sorry but the new cree cxb LED's can outperform hid,s. I run cxb 3070 at 36vdc at around 1000ma . They are able to handle about 1800 ~1900 ma . This means a lot less heat , and with the use of optics can keep up with hps in the intensity of light and run more efficiently. Search Cree cxb and you,all soon be up to date.
+Garry Carley Thanks for your comment Garry and no need to apologise for it! :) Technology is developing at a tremendous pace so it's inevitable that my presentations will need updating at some point. I am very interested in the latest generation of LEDs-I think it's time I jumped on board and I look forward to some comparative grows. Thanks again for chiming in. I hope you're subbed so you can follow my progress.
Wrong. I've been running a top of the line LED light from California lightworks. A solar storm 880. Then I ran a high pressure sodium in flower. No comparison the HPS buds were so much bigger I mean 3 times the size and yes quality was still there.
HPS is losing big time with the tech community. About every data center I have worked inside of in the past 4 years is now retrofiiting for LED's. Besides plant growing & softer outside lighting for streets lamps, these HPS lamps have no purpose for commercial buildings. They are expensive to run. The lifetime is short. Proper disposal is a pain. And they are NOT eco friendly!
Optics R US Thanks for your comment. I agree, perhaps HPS is finding its “niche”. Lol. Lighting to help human workers avoid walking into into chairs, tables, walls and other objects in modern working environments is a fast-moving and exciting application area - one in which LEDs are clearly excelling. Lighting to drive photosynthesis and photomorphogenesis in high DLI flowering plants is lighting for a very different application and with very different goals than lighting for human working environments. In the latter, we seek high CRI diffuse reflection, the former we seek deep absorption of the energy, both at the micro and macro level. I agree HPS is expensive to run and troublesome to dispose of properly.
Still way cheaper than an equivalent LED. You can buy a whole HPS set up along with spare bulbs and spare ballast for a fraction of the cost of one GOOD LED. Not the Chinese junk on Amazon (which is still way over priced IMO.) They are a total waste of money, and when the Chinese junk fails, you are out all that money. Buyer beware.
Нови Сад Србија LEDs still produce lots of heat, they typically lack angular / radiant intensity for canopy penetration in flowering and remain very expensive. While they have some advantages (the lack of IR can produce nice squat and compact plants in vegetative growth) and are advancing quickly, I think it is an over-generalization and mischaracterization to claim they cannot be beaten.
@@Just4Growers It was like over 6 years ago ! I built my heatsink for 10 dollars and added leds 50w each 9 of them pulling 420w total and have killer penetration and low spread so great efficiency. All cost about 50 dollars ! And i can change led any time... Any spectrum any wattage... It is cooler with only one little fan.
Нови Сад Србија I commend your DIY skills amigo, and I’m looking forward to getting hands on with lots more LED fixtures this year. I’m excited for the technology and believe it has great promise and, in some applications, good results, but I’m just as excited by other lighting technologies such as CMH.
Thanks for your comment. DIFFERENT to LED would be the way I'd put it. Sure, if you're growing in Alaska or somewhere 'naturally air-conditioned' then HPS could be a smart way to go. Same goes for winters in continental weather areas like Michigan. But more and more commercial growers are turning to LED because of its superior broad spectrum and higher efficiency. I believe that we will continue to see commercial and hobby growers switch to LEDs over the coming years.

You cant beat leds. If you dont care about efficiency and have money to waste on a long run and control insane amounts of heat then you are okay 😆😆😆😆
Нови Сад Србија LEDs still produce lots of heat, they typically lack angular / radiant intensity for canopy penetration in flowering and remain very expensive. While they have some advantages (the lack of IR can produce nice squat and compact plants in vegetative growth) and are advancing quickly, I think it is an over-generalization and mischaracterization to claim they cannot be beaten.
@@Just4Growers It was like over 6 years ago ! I built my heatsink for 10 dollars and added leds 50w each 9 of them pulling 420w total and have killer penetration and low spread so great efficiency. All cost about 50 dollars ! And i can change led any time... Any spectrum any wattage... It is cooler with only one little fan.
Нови Сад Србија I commend your DIY skills amigo, and I’m looking forward to getting hands on with lots more LED fixtures this year. I’m excited for the technology and believe it has great promise and, in some applications, good results, but I’m just as excited by other lighting technologies such as CMH.
Superior to LED and used by all commercial growers for a reason.
Thanks for your comment. DIFFERENT to LED would be the way I'd put it. Sure, if you're growing in Alaska or somewhere 'naturally air-conditioned' then HPS could be a smart way to go. Same goes for winters in continental weather areas like Michigan. But more and more commercial growers are turning to LED because of its superior broad spectrum and higher efficiency. I believe that we will continue to see commercial and hobby growers switch to LEDs over the coming years.
It doesn't beat LED buddy
^__^ my HPS grow bigger better
Yes, yes it does beat LED, buddy.

LED > HPS
This isn't true
What isn’t true?
Yes it is you would even lose efficiency if you do that to a grow light
thanks for the reply . I believe we worked it out to be about 50% , others claim 55% if my very poor memory serves me well . I use 3500k and a large 78mm *25mm lense . The photons it produces are incredible ,and l can turn it down if needed . I love the tech of it all ,but its crazy how quickly its advanced in the the last 4 years that I came to be enlightened by them
+Garry Carley Please refer me to any website that sells an LED fixture which purportedly converts electricity to PAR at 50% or 55% efficiency!
