- I've looked at one of these before, and the only real change is the better choice of cable and the omission of the case around the internal power supply.
This unit is fairly functional. It produces a useful narrow beam of light that is ideal for mirror balls and creating a sharp beam through hazy air.
The power rating on the listing is double the reality, but to the benefit of the LED and driver which both stay surprisingly cool, largely helped by the good (ungrounded) heatsink.
The optics are pretty good with a glass front lens and adjustable inner lens.
Everything can be serviced by people like us who have no qualms about changing a driver or LED.
This is another of these products that is worth getting for the case alone as it could form part of a customised light for use at any desired voltage, colour and intensity.

I always love when you turn the lights off. It's cozy. It would be neat if you made some episodes in a series called "Clive after dark" or "Dark mode" or something like that where you do the whole episode in very dim or no light with some atmospheric flame-candle lights and stuff.

Thanks, papa Clive.
I'm now considering whether a few lights like these placed unobtrusively around a room and projecting their dots to the ceiling would be a good, diffuse room light.
That's "Healthy Papa" Clive
Healthy Papa will always be my favorite bear.
It would be exceptionally dim room light.
@@stargazer7644 one would be too dim, certainly. How many do you think would be bright enough?
@@Milamberinx At least 10 - and that only if you don't need the lights to work on something. I don't think that it would be comfortable due to the colour, though. I prefer to use warm/cool-adjustable LED strips.
Found your channel a few weeks back and i have to say that im loving the content

This reminds me of a flashlight I could start unscrewing the main lenses and see a perfect “shadow” of the LED chip.
Most likely it was a torch not a flashlight. A flashlight is just a camera flash as a light. Such as on a phone.

I love Chinese products. They have magical powers. They transform a 1w led package into a 3w led by soldering it to a pcb. then they transform that into a 5w led by putting it in an enclosure!

Its great to see a normal video at this time!
This was a good recovery from the FLIR phone debacle video (deleted). Good stuff. Stay on track, Clive.
Why was that a debacle? I didn't see it.
@@Heizenberg32 Clive made the mistake of thinking you could detect if someone has COVID-19 based purely on their forehead/skin temperature, which was rather incorrect ( he was playing with a phone which had a built-in IR camera ). People were quick to correct him so he took the video down. The phone was still a great gadget though- it deserves a new video showing off how well it works for reading temps on items...
@@Heizenberg32 - It wasn't up very long. Clive had _misinterpreted_ results of using an IR FLIR camera (on his phone) to _find_ those with the _current_ virus going around. There was lots of feedback about the _errors_ of its use.
Ohh, that one! My mistake, I did actually see it. Did anyone really take that seriously? I recall that Clive played it straight, but I took it for a troll video immediately.
The debacle was that he went to the pub with his mates.
ive had lots of cheap $1 chinese flashlights that often show that same chip shape at one end of the focus beam. its neat. you can easily see the bond wires.
Dimple in the heatsink is the ejector pin for the casting mould. They used that section as it is the thickest, so the chances to distort the hot pot metal as it is popped out of the one half of the mould is less. There will be a matching set of smaller ones on the fins at the back as well.
After watching so many of Big Clive's videos I could've swore that the video title was "Very useful LED that is a good base for circumcision"
You'll find the lasers good for such uses on the channel "styropyro".

Mick slow but most of the time trustworthy.
@@mcomiskey7It's just like every other chinese seller in ebay or wish or whatever. The cheapest china post typically takes about a month, give or take 1-2 weeks. There is a more expensive shipping option called e-packet which usually takes about 2 weeks. If its available it can be worth it since its usually only a few bucks. Depends how fast you want it. Sometimes they dont even send it from china, they'll send it from various other countries like Kyrgyzstan or Laos or Malaysia and those usually take even longer.
Never can have too much LED info! Thanks, Clive! Keep up the good work.... Stu
I made some insulated washers to hold those type of LED's down by using a hole punch on a pot-noodle pot, and then putting a hole through the punched out pieces. Pot-noodle tubs are polypropylene and can handle the heat an LED produces. I didn't want to wait for an order of washers, and enjoy recycling and pot-noodles. I used to work for a disco light manufacturer years ago, and they usually have the light focused down to a small spot just as it hit's the gobo, but have the filament focused a little in front so that you get an image of the gobo instead of the filament, the second part of the optics focuses the image of the gobo. As long as you can focus the LED down to a small enough spot on the gobo you should be good (otherwise you will waste a lot of light), you want it just out of focus so you don't see the LED chip shape in the image. Good thing about LED's is that you no longer need a metal gobo to handle the heat from the lamp - it's considerable even for a small fixture that uses a filament bulb, as I found out by sticking my finger at the focal point.
Nice tip. Now if only they sold pot noodles in mica pots we'd be laughing......!
Clive I’ve been watching some of your videos for a quite a while and I’m a big fan I’m also an electrical engineer who covers all types of electrical contracting work domestic commercial ,fire alarms ,intruder alarms ,CCTV ,access control, entry phones ,data networking ,telephones and aerials you name it if it’s got a wire connected to it I like to do it and as an engineer I find what you do fascinating so while I’m sitting here locked in doors because of this virus I’d like to thank you x
You're in good company. We're all technical people who use more technology for recreation.
Thanks Clive, I'll probably pick one of these up to play with :]
This is some random stuff I'll put on my list and meddle with when I finally escape!
Looking at the beam this puts out, it puts me in mind of seeing how well something like this could be used to make a much tighter laser-like beam, for research purposes of course, not for mounting above the front door on a PTZ camera to use as a laser weapon... :P
The colour of 'full spectrum' growlights is often referred to as 'blurple'.
Or "maaaaan".
The blurples are the ones with just red and blue to hit near the peaks in chlorophyll response but they lack any emissions from cyan to orange and are not "full spectrum" from any emissions standpoint. The real full spectrum lights are the ones based on blue or indigo LEDs with full spectrum phosphor for the rest of the wide band emissions and they emit going clear down to red. The Samsung LM301H is a good example of a full spectrum LED used in grow lights. www.samsung.com/led/lighting/mid-power-leds/3030-leds/lm301h/
I've only heard "blurple" when describing the color scheme of the awful chat/voice client Discord
@@Knaeckebrotsaege what's wrong with discord? Besides not having e2e encryption
@@Peter_S_ Pretty sure that's why he put "full spectrum" in quotes.
oooh these. I used them as a pinspot for Javert's suicide during our production of Les Mis. Perfect in a blackout to hide the complete lack of special effects. Only problem with ours is that the shape of the beam is the shape of an led chip, a square with a rectangle stuck on the side.
I would definitely change the flex for a 0.75mm 3 core flex and fit the CPC to the heat sink on the back. Other than that, it's a very good project casing and spot light for disco's etc.
Personally, I would use an external 'plugpack' type power supply with limiting resistor and one side of the secondary firmly earthed. While I do work on switchmode supplies, I am extremely wary of the possibility of contact with the mains on both primary and secondary sides. Still live and kicking after nearly 7 decades so I must be doing something right.
Great stuff Clive , love the deconstruction & and analysis etc you do .
Especially liked the review of that dodgy flaming / fireworks doll ' fanny flambeau'
Unbelievable ! Quite frankly .
Keep up good work 😂🤣😂🤣
Looks like you could actually put a small LCD screen in front of a super bright LED in there & have a great base for a small diy video projector... 🤔
You could also do transparencies for Halloween projections, etc
Who needs discharge resistors when you have a discharge finger?
I know a man like you needs no ideas for video content 👍 and I know you have randomly mentioned items/tools you use, but I think a video of the tools you commonly use or even very useful lesser used tools would make for a very good video.
I'm an engineer and to me that seems like a solid video but it might not be for everyone. Then again I think it's safe to assume most of the viewer base of the channel is tech inclined or people interested in learning. Love the video as always.
It's a video that gets asked for frequently, and as I just (almost completely) tidied my bench up this evening, it's very viable.
@@user-gx6jb6wc5g If it happens awesome 🙂 if not the content as usual is always entertaining enough.
Damn, I could have used 4 or 5 of these for my party last week. Oh well. Live and learn.
I play in a covers band and am our lighting "tech" 😉 We have a modest light set up with decent quality moving heads, pars etc, I bought some of these a while ago and they are fantastic for shining at angles across the set up when we use the hazer. Very effective for the price. There's a zoomable 30 watt rgbw allegedly which I'm thinking but not sure of the beam angle, I'd want straight like these. I'll get to the bottom of it.
Class One appliance with no earthing? Are you going to earth that metal backing clive and put a proper plug and lead on it with a cable restraint?
I calculate the beam spread as about 2.5 degrees, compared to 40 for a GU10. A GU10 at 6m has a spot size of 4.3m diameter, which is 17 times as wide, or 289 times the area. At about 70 lumens per watt for LEDs, the spot is receiving 140 lumens. To achieve the same brightness over the whole area, the GU10 would need to output over 20 kilowatts
2.5W at 0.48 power factor is about 5 watts apparent consumption (which is what you pay for during peak times in several places), so the 5W on the listing seems pretty fair. It's not a 5W LED (which is not a good way to measure brightness anyway; that's measured in Candelas), but it is a 5W _lamp._
As it uses a SMPSU, feed it 340V smoothed DC and measure the current. That will tell you the real actual power.... 😉
For the purposes of people paying the bill, connecting it to a ~230V AC outlet and looking at the power meter is what tells you the "actual power". ;^)
RFC3514 - not if you are running it off a high voltage battery that is charged via solar power...
I'm not.
Optically it's a telescope in reverse i.e. a collimator.
I saw some amazing miniature spot lights at some museums. Probably the size of a thumb. They had flaps on them light stage lights. Have you ever seen these before?
The flaps are called "barn doors", but Google doesn't find me anything thumb-sized; only rather bigger :(
The "tooth test" sounded like it cracked at least 3 teeth! 3:28
You tap it on your teeth.
Grow crop circles on neighbouring lawns.
You could out in a real Cree style LED similar to flashlights and use it as a spotlight, even during a power outage with an inverter or even convert it into a DC light and run it from a couple batteries. I'd hack it to be able to operate from a power supply or batteries that way it can be used in many situations.
If pressed (which won't ever happen but grant me my fantasy) the manufacturers would just say that the LED puts out as many or more lumens as an incandescent (or arc, given its advertised theatrical application) lamp that ate five watts at the plug.
Given the greater efficiency of LEDs they'd be more than right, too, but they could at least *say* that up front.
I see similar things on home-use light bulb boxes even after incandescent bulbs have been off the market for quite a while.
Hey clive great channel would be fun to see a sky remote modded to a hi power infrared torch be fun to turn people's sky over at range lol
Nice work! 👍
Now it just needs a strobe feature 🥳🥳🥳 love it!
Given the reliability of some of the power supplies it will probably develop one itself after a while.
bigclivedotcom fingers crossed lol
@@user-gx6jb6wc5g Haha, those chinesium supplies would do nicely for strobing.
when you actually need/want strobe feature thats in every flashlight, its nowhere to be seen
Frogz so true
Blurple coloured lights make people think you are an medicinal indoor gardener lol
There are at least tow different versions of this around. the other style has a considerably bigger an better heat sink. if you look closely i think the picture in your listing actually shows the presumably older but way better style.
The 5 watt rating is really a 5 VA rating in preparation for the electric rate switch to VA.
Heh, we'd be ever further away from meaningful indications of actual light output. Imagine looking at a light in a shop and needing to know its power factor to know how bright it'll end up being.
@@Milamberinx And that's why I look for lumen or candela ratings rather than wattage or amperage.
I wonder if you could design it in a way that you could move the LED lens assembly to and fro to adjust the beam dynamically?
Cool device!
I would use a dab of hot melt glue to route the wires. Then you don't need to worry about pinching them during assembly.
and cut the heatshrink and redo those joints then heatshrink them back
@@urugulu1656 - I was referring to not pinching any point of the wires not just those poorly done connections under the heatshrink. The wires don't need to be loose for assembly as all the wires come through that one side of the enclosure.
using the word hack in it's true sense ... priceless ;)
I wonder if it could be used as an image ie,slide projector?
It would require some more lenses. But you do get small LED gobo projectors for shop displays.
@@user-gx6jb6wc5g Bought one of those Xmas gobos with a reindeer image from Asda once ....absolutely useless LOL

Clive, have you ever played with tactile transducers, aka bass shakers? Those could make an interesting teardown & test video.
I have four 25 watt 4 ohm bass shakers I bought years ago, originally bolted two to the back of my computer chair which were driven by an old amp from the .1 output of my 5.1 AV receiver, films & games were fun.
We used butt-kickers on the air-bag lifted platform in the Armageddon attraction at Disney Paris. The platform could vibrate and then drop suddenly.
That sounds like fun. My 5.1 receiver has a test mode which outputs white noise to the speakers individually, when I output to the subwoofer and crank up the volume it feels like an earthquake, I wonder if you could use butt-kickers bolted to the floor to convince someone there's an earthquake.
Perhaps a future Manx beard club prank? :)
The light is 5 Watt - apparent power!!⚡⚡
What could possibly go wrong with a manes voltage electrolytic pressed against a 70C diode?
I have 10 of the multicolor DMX version.
Looks like a cree XP-E LED.
Not bad.
could you make 1 with milar emrg blanket and cardboard or is it more to do with lens?
I was watching you handle the heatsink with LED attached and squirming, knowing that the LED was effectively connected to one side of the mains via the power supply. Somehow I am loath to trust the insulating properties of low cost powdercoat on the heatsink. And I certainly don't trust the white paint used on the LED pcb itself. Could the LED heatsink be safely bolted to the heatsink if the powdercoat was removed from under the LED? ie would the heatsink become live?
So, I purchased some of those photography sphere crystal things, and was farting around with some LEDs to see if I could see the chips/bond wires. I think I ended up actually seeing the PN junction in operation.
Just a quick question: is the Hopi power meter calibrated at these low powers? Just thinking that dead band and resolution could hide some power consumption. Perhaps an opportunity for a calibration video?
The Hopi looks like it could be fairly accurate for dealing with light, low crest factor loads but I doubt they ever receive the necessary calibration step to make them truly useful for the low range. I've studied the CS5463 used inside the Hopi fairly extensively and it's spectacular for what it is, but it has far more capable siblings. I hope to offer Clive an upgrade soon.
I use these identical spots on a mirror ball....👍🇮🇲
They're perfect for a mirror ball. Nice tight focussed beam.
bigclivedotcom indeed.....they work absolutely spot on....👍🇮🇲
Yeah, noticed the halo early on with your replacement LED. The original one was much better - had a nice crisp edge to it - I say with my followspot operator's hat on !
It's not helped by the wide point of phosphor.
@@user-gx6jb6wc5g On a similar but completely different optical 'feature'. Entering the rear - as we do, of theatres, I didn't put the light on but closed and locked the door, removing the key. For whatever reason, there's a bit of wall the other side of the door which one has to walk round. But on the wall, upside down was the scene outside (daylight) but a bit blurred. #camera-obscura with a keyhole rather than a pinhole. Just a bit apt to spot a projection - underneath the original back-projection projection room !
(I guess that old proj room was hung off the back of the building. It was 'outside' underneath it - so, over time the boxed in the underneath and maybe the bit of random wall was additional new support for the old proj room !)
Well it's 5W apparent power. ^;)

Clive - I know you’ve made videos about UV before, but I’ve seen a lot of products just now like phone cleaners that use UV-C LEDs. Are these effective? Can LEDs produce UV C? Some say it will clean your phone in 3 minutes? Is it all marketing hype? Cheers
Don't, it's a really bad idea
It clearly needs a RGBWW LED :-)
Sir you get hold of good strange kit can you get hold of a proper portable strboe light ??? Not a poxy led that flashes
3:00 - bit of 'bent' wire is called a circlip ! (Figure it out Clive, I know you can.)
In PAR cans it's usually called a retaining ring.
@@user-gx6jb6wc5g Alternative name for the benefit of the uneducated ;) 'Snap ring' is another alt name for a circlip.
The 'common circlip' has 2 holes near the ends in which to fit circlip pliers for ease of fitting & removing said clips (I assume you know that already too) and some have different end arrangements - such as simply bent ends so any pliers would do - and various styles of clip exist but all work on the same principle - a spring clip fitting into a groove.
(There are other 'rings' that fit into grooves that are not springs and are held in place with some other means - that have the same function as circlips.)
i just ordered one of these lights - how would i go about making it fade on/off like an incandescent bulb (fade up when powered on, fade down when powered off)?
Hey Clive, great video, what size is the star base on the emitter?
There's a type of fork lift with a blue marker light on the front
How high a watt Cree system can you increase it to without a melt down?
Thoughts on putting a little diffuser in front of the LED to eliminate shape projection, to provide a more appealing spot? What kind of intensity loss would one expect?
It could result in a much wider beam. This effect is more about projecting a tight beam of light than projecting a circle. It looks good in hazed air.
Would painting the inside of the housing white help with getting more light out of it or would it cause the beam to not hold it's pattern. I have painted the inside of turn signal housings on motorcycles white and it made a significant difference to the eye but it was to make it stand out more with little need to hold a pattern for a distance. This is a cool product and I have ideas forming for it.
That would result in a very wide splash of light. The whole point of this light is to project a tight beam through hazed air.
Only advantage here with a glass lens is scratch resistance - but introduces fragility. The lens inside is anyways plastic. It's not the same logic with cameras here.
I have a bunch of antique magic lantern slides used in silent-era cinemas for ads between films. I wonder if something like this could be bodged into a cheap magic lantern projector. The real ones cost a fortune.
A bare white LED in a linebach projector could work in a dark room.
@@user-gx6jb6wc5g Ok, now I just need to google linebach projector. :)

These are commonly used on 1w or 1w x 3leds or5w max power driver this is 1/2'watt led may be blue or uv this is still beter as compared to China standards
Does the front glass lens get hot or could you use printed paper rondells for a temporary colour change provided you used a white led ? Perhaps even glue in a thin round and flat piece of acrylic/plexi before the lens to put the "colour filter" on.

60/40 is readily available on Amazon in the US. Doesn't look like it's too hard to find on Amazon UK either.
I built mine using a 18-34v output 600ma and it only flashes. Not sure if hugher voltage out. Means its starving current, would be my guess.
That may be due to a driver and LED mismatch.
I have seen those CREE LED's on eBay before, but they say 1watt.
How do you know what wattage a red like that is if they have no numbers on them ??
You measure the power draw at the rated voltage
0:56 Yeah I know Divergence. Watched the whole trilogy.
It's based on the virtues of stoicism - I believe.
I wonder if the dimple under the led is to accept a plain LED bead? If you had a bead then a small bracket to screw it down tight directly to the heatsink.
then you should ideally put in an adaptor plate for the cases where you use a cob so you get a flush surface either way

Какие там линзы? Какое фокусное расстояние?
Whenever I see a Chinesium product advertise its power I always assume it to be only about 30% to 40% of the actual.
So far I have rarely...as in a couple of times out of hundreds...been surprised by a truthful rating.
For LED lightb ulbs they commonly quote the power of a filament lamp of the same brightness and imply that's the actual power of the LED. So actual power is more like 7-10% of the advertised power.
What lens to use for 100w cob for tight beam? Basically a 100w version of this
You get complete sets of mounts and lenses for standard cob styles.
How about putting a small LCD in it?
Should that metal back be earthed ?
15:40 That's not full spectrum.! it is a quackery of multiple colors not in violet range to mix in. It is evident in chromatic aberrations around the halo of the light spot.
I managed to pick one of these up for 25c but one of the LEDs is dead. I really need to get around to replacing it.
Just increase it until you get a meltdown, than decrease a watt.
