  • Imagine trying to sleep and your neighbor turns on the sun

    • Lmao

    • Even scarier is if you're trying to sun and the neighbor turns the sleep on.

    • turn on the moon then

    • We have someone here who has a *streetlight* mounted to the outside of their house. So- no imagination needed. A slingshot sometimes would be nice, tho.

    • You could probebly sleep through, with the curtains drawn under the blankets wearing sunglasses

  • British man got tired of the shitty weather in england, creates his own sun

    • 🤣🤣🤣

    • @safcforme oops

    • I'm laughing so hard 😂😂😂😂

    • Your comment deserves more thumbs up 😂

  • I think it's incredible how broad the spectrum of people's hobbies is. An LED is just that to me, an LED. But to someone else it is a whole lot more. You just gotta love that.

    • I was browsing Reddit and found r/flashlights , pretty cool and wholesome subreddit

    • Very nice comment.

    • @Travis Pratt I Googled 15 years old forum posts and some people were modifying incandescent lamps just like people now are excited about LED COBs.

    • I think a lot of it is due to the EXTREME variety of specifications and operating characteristics of not just different brands and makes but also different bins of same name leds, the cheap leds are so annoying once you’ve actually analyzed them and compared them to better performing leds. Plus it’s fascinating just how much light we can produce with such little electricity compared to incandescent bulbs people used for a long time.

    • You should see how many flashlights I have, and my collection is minuscule in comparison to others

  • Cost Chip-32$ Heat sink- 468$

    • @test test Its not too difficult to make your own aluminium furnace. Cut out the middle man and start casting your own today!

    • @Ivan crespo not all cobs.this one is just new and powerful. . my 100 watt vero 29s were only 8 dollars a piece so for 500 watts for 40 bucks. the heatsinks , now that is a different story lol. cobs are actually pretty cheap.

    • @Melaz Music 😝😝

    • This infuriates me all the time building lights. The led chip, working using near theoretical physics, and being produced in a plant costing billions of dollars, costs almost nothing, solid chunk of Aluminum, scrap price of $0.21/lb, costs hundreds of dollars.

    • @Ivan crespo correction GOOD leds are expensive :P

  • Husband: "Is that a UFO? What IS that?" Wife: "The neighbor got a new light again..."

  • This may seem a silly question, but ... Could one use a convex regular glass lens and focus the beam for burning things? I'm thinking art not malice or destruction.

  • As a space engineering student myself, I really enjoy your videos. It would be really interesting, to mill a passive heat sink with some heat pipes. How big would it need to be?

  • You could probably build an amazing projector out of this, using the LED as the backlight

  • I'm a theatrical lighting designer and this is very fascinating technology to look at for me. Could be ideal for stage lighting.

  • scientist: how many lumens you want? me: yes

  • Imagine someone flexing "I have 500$ led"

    • @Jacob Dennis to

    • @Jacob Dennis to

  • Deberías darle subtitulos en español a tus demás videos, son muy buenos y estoy seguro que muchos más habla hispanos nos gustaría eso 🤩

  • I reckon this would be very useful for slo-mo shots too, as the faster the shutter, the less light goes to the sensor meaning you need a lot of light.

    • A lot of LEDs flicker because they use a PWM dimmer that rapidly turns the led on and off to raise/lower the brightness of the light. A voltage based dimmer (which increases/decreases the voltages, doesn’t cause flickering

    • @꧁ ꧂ LED does not flickr, however if you apply pwn, the power supply does.

    • @꧁ ꧂ to prevent flickering in dc circuit check the power supplys current rating, sometimes the electrolytic capacitor is Not able to handle the stabilisation of the dc voltage so you will get an ac part in the voltage, its just a simple adding of another capacitor and maybe a beefier power supply

    • Not really, dc wont do that. Thats ac.

    • FinnishArmy no LED flickers its not good for slo mo video making

  • Oh my. This is bananas! I could see these being really useful for transmission towers especially, costs a lot of money to send someone up to change those bulbs!

  • It would be interesting to see how you can utilise this light as a projector setup light

  • Imagine a 4k screen made out of those LEDs. This would be visible in space.

  • Is my sight supposed to come back? I still can’t see..

  • 3:43 To convey brightness, I think it might be good to try it as a fill light when you have direct noonday sun above you. That has been what I have been looking for when I see reviews for lights such as the Aputure 120D II and 300D, just to see how bright it is. If you ever get your hands on those two lights, I would love to know how your lights (the gooseneck and this light) compares to them.

  • Hey ! great video, as usual ! I know you did this one quite some time ago, but would you care to give a part list (with links would be awesome !). I'm planning to turn an old 2kW tungsten Fresnel into a LED daylight projector, andi this Led looks perfect for it ! Thanks !

  • This thing is perfect for slow motion filming. Plenty of light, and a good CRI

  • It would be awesome in an automotive paint booth. Looks like it could easily replace what we have. When it finally breaks I’ll be looking into this the colors will help with paint matching. Everything looks different in the sun. Would be great to mimic it.

  • Imagine how amazing a spotlight with let's say 20 of these would be.

  • It’s amazing how that one LED needs that gigantic heat sink!

  • Can it be pulsed at 100A~200A fast enough to be used as a photo flash? The idea would be to make a flash that you can use for night time high-power zoom photography. One would need to use lenses to focus the light at a distance (say 100m) and be able to adjust the size of the beam. operate it at 12A for beam adjustment, then 100-200A for a flash, taking a picture in full color. I know, its a dumb idea, but I am full of dumb ideas.

    • High pulsating current reduces led lifetime significantly

    • Not a dumb idea at all.

  • this would work well for slow motion recording projects where there is a lot of light needed

  • Imagine that heatsink in a computer! If that doesn't get your CPU down to room temp I don't know what reasonable air-cooler will! Also, the shadow thing at the end was actually lovely. A feature length movie needs to be made purely with shadows like that!

  • How such a small object give out so much light is amazing. Is it stronger then the sun, In 1:1 ratio?

  • Getting close to a practical LED replacement for theater follow spots there, wow. Considering the bulb alone for a professional follow spot runs over $1000, thats mighty tempting.

  • I love how genuinely happy he is in this video 🙈😹

  • I rly need this in my PC as an LED component! Would be "lit". I'm sorry.. xD

    • HA! Amazing -- you don't see very many dad jokes in the comments sections. That was great.

    • ???

  • I guess this is the LED Fractal Design will use as the power indicator in their next computer case...

    • The current one is already keeping me up at night. Got to drape a clothe over it

    • I didn't know this was a common complaint. My define r5 lights up my room at night to the point it disturbs my sleep.

    • @Th0mas omg yes

    • @Th0mas oh shit Bright and blinks 😵🔫

    • More like my Coarsair case's sleep led.

  • DIY Perks: Look at the small package they managed to fit all that brightness into. Also DIY Perks: Please quietly ignore the ginormous, elephant testicle sized, heat sink the thing needs to be mounted to so it doesn't catch itself on fire and marvel at this little square.

  • I thought of a lighthouse as a practical implementation but, hey, even going cosmic and cloning the sun would do.

  • Even understanding the problems, I would like to see that I can put that 500W led in this project and make a comparison before and after. But I think I would have to go to the water cooler on the led.

  • You can make a decent (and cheap!) 4k DIY projector with this powerful LED and fresnel lens =) Just need to find a good 4k laptop display to dismantle.

  • I had no idea a $500 led even existed. Thanks for sharing!

    • @jeffrey G could you put a link to the helios 1500w LED

    • @Cooper LOLOL

    • I dont have doubts that $500 LED exists, I didnt know that 500w LEDs existed, which is quite insane.

    • this is the only reason i clicked LMAO, got a couple beans growing myself

    • true, and i dont know the actual cost for the wafer itself, but when your talking about a 1200 watt led grow light that cost 2400, it might be safe to assume the wafer cost more than 500. Now consider they have a 2600 watt variant...

  • Here is a great project for you! They say that LEDs are also solar energy receivers to create energy from sunlight and it would be interesting how much solar power it can create!!

  • Hey. Did you managed to make a silent cooling solution ? If yes, can you please provide some hints?

  • Looks like it would make a great cpu heatsink. Do they sell it separately?

  • Outside of the relative superior lumen per watt performance aspect. Curious as to why one wouldn’t simply utilize halogen lighting for a studio application, given halogen has a CRI of 100 and costs a $1...not $500, and is infinitely simpler in a myriad of ways.

  • Hey, I work at Sony Pictures and I walked past a set today that had such an effective artificial sun that I thought they had opened the roof somehow before I looked up at an array of thousands of white LEDs. Grid pattern, about 3 square inches between, and 30 feet above the ground. Not sure if there were any kind of optics (shades, reflectors, lenses, etc) but they looked bare, definitely no diffusion. Maybe you should cover your ceiling in LEDs!!!

    • DIY Perks You are quite good at electronics mate! I found a use case for the 100w Yuji LEDs that people might think are cool especially for the good CRI. Projector bulb upgrade! No need for weak bulbs or buy new ones every 4000hours. 4k projectors like the Sony or Epson have really weak bulbs of 2200lumens. i have an Epson 1980wu with 4400lumens which is perfect even for daytime viewing. What you would need is to close loop watercool the LED like for a CPU. Apply a lens to the LED. And you would need to via multimeter find what PWM or ballast checks for the correct power draw so that the projector thinks that you have the correct bulb in place. i think you might find it a fun challenge! :) It won't be illegal either just a void of warranty. I'm sure many viewers could loan you a projector and have faith in YOU!? There are almost no videos of this on ILaward either so you'd get many views! 💛💚

    • That's just our in-between job. Wait. No. Nevermind. Screenwriting is the in-between job.

    • Break out the 18k if you wanna light up the back yard..

    • NO see I had this idea of using those foot squared panels on the ceiling and hook them up to an Arduino so you can basically use them as giant pixels. Play a game of pong or snake on your ceiling, for example!

    • It is probably up high so there are more accurate shadows

  • If this is the way you talk in front of a video camera you should do it more often I truly enjoyed watching this video because not only that it's a great product that you have demonstrated it's about how happy and pleasantly you have done it thank you for this nice video and may you have many happy days in your studio. Respect.

  • Use liquid metal instead of thermal paste between the led and heatsink. Linus tech tips uses it on cpus/ gpus and gets ~10 celsius cooler operation, so maybe you could use a less noisy fan.

  • Damn LEDs are getting so amazing :D Now just make a quiet hover-capable drone and we can make some sweet alien hoaxes :)

  • me: crazy over how bright a phone light is Mat: STAYS CALM EVEN THOUGH HE IS HOLDING THE SUN IN HIS HANDS

  • You should put it on a drone, point it downwards, and make an artificial sun.

    • @Ashok Kumar Saxena Seeing as there are battery powered drones that can carry full on humans, I would have to say yes, it's easily possible.

    • @joe nodden for real????

    • @Ashok Kumar Saxena Yes it would work with battery operated drones.

    • Won't work with battery operated drones Will work with drones which uses diesel engine for fuel source and those drones cost around $10000 And aslo you need a special license to register and fly those, which can't be done on website

    • You would light up every 911 switchboard in 11 counties.

  • This would make a great light for projection on buildings.

  • would this LED be as accurate of a solar simulator as a Xenon arc lamp?

  • Wonder if using a water cooler would be more effective vs the massive fan heatsink

  • I feel really bad thinking of Ramsy Bolton when I see Matt who is such a genuine and nice person. Just had to get that off my chest. Anyway, thanks for uploading, your channel is one of my all time favorites.

  • What happens if I retrofit my car to have like 4 of these in my headlamps? Like 1 in each main housing and 1 each in the fog light housings?

  • I’d love to see a video on how you wired the server power supply.

  • It's gonna be kind of hard to use that when you have a heatsink that looks like it belongs on a i7 8700k overcloced to 6ghz, and doesn't that thing burn your hands when you hold It because heat is passing through the alluminum. And how the heck has Linus tech tips not done a video on this?

  • Awesome. Can’t wait to see your artificial sunlight. It has been a major point of contention for my brother and I.

  • Everyone from my area uses these as headlights, I swear...

    • @Eric de Gaston There was a study conducted which concluded that lack of blue light actually decreases 'visibility' when driving at night. I think it had something to do with street lights, though I'm not entirely sure.

    • I love lamp

    • @Eric de Gaston halogen as in standard bulbs? the stock h4 halogen bulbs for my bike you couldn't see much of anything at all. very much red spectrum but I would call it dull yellow and you couldn't see much of anything useful. swapped to led and bam light that's worth using.

    • And.......its useless....

    • Lol

  • I like the compact form factor of this LED. But for the purpose of indoor gardening. I'd love to see what they could do with a panel format. Like a Quantum Board. And for those thinking I'm meaning pot. No. I am in fact talking about vegetable gardens.

  • nice one... wondering if changing thermalpaste with famous brand could give better operational temp

  • I can't help myself but to ask you: Would you like to pair it with a Fressner Lens, like those theater spotlights?

  • Could you mount this on a motorcycle or moped? Preferably more than one? I'm real tired of almost dying when I go out for a casual breezy night ride. (Not entirely a joke btw lol I would absolutely rock an absurd light like this! If those jerks can have train horns, I can have the fucking SUN!)

    • @Hoch134 Yeah, though I assume it isn't really good since you may damage other drivers eyes

    • @Alex It hugely depends on the place you live at. In Germany not even a bicycle light would be legal on a motorcycle. However in India nobody would care if you mounted an actual sun onto your car or motorcycle.

    • danteelite I’m not sure how legal this can be

    • Well I've mounted a 300m range flashlight to my bicycle. If the restrictions of your country allow it, just do it... But you'd have to make sure that the LED gets its power since 500W is even a lot for a car alternator.

  • I could so use this for shadow puppetry. How far away from the source were you when you did the Shadow work to the wall? How loud is the thing? Would it burn a hole into paper?

  • Hey ! i would like to know if you can actually warm up things by absorbing the light of the LED, like putting it in front of a dark glass or a metal painted in black. I wonder how hot it could be !

    • Since the CRI is 98 it will naturally put out uv and infrared. So yes it will make your hand warm if you put it in front of the light.

  • Which Kelvin temperature would simulate more realistic daylight/sunlight? 3200k or 5600k ?

  • Am I missing something, 54lm/W that's rather poor efficiency with a crazy price tag of $500. Bridgelux makes Vero SE 29D that would match this LED in terms of CCT/CRI and lumens at $25 (LED only) and half the power 185W with the efficiency of 132lm/W

  • All good that it's small but the only disadvantage is that it needs a huge cooler...

  • Any idea of the BTU's it puts out? It must put out a LOT of heat. These would be great for growing. What's the PAR rating?

  • Damn imagine a lightbar with like 20 of these diods.

  • this would be pretty good as offroad lights

  • I think what's most impressive is how it grew in size from the thumbnail of this video. That's worth some serious scientific investigation. I mean it seriously seems to break the laws of physics. /s

    • Lard British Looks like maybe the 100W only version in the thumbnail he made videos about those before i think.

  • A little led needs a more powerful heatsink than I currently have on my overclocked prosessor

  • You can also use it to show how the moonlandings were lighted.

  • 5:05 thanks you answered my question I was absolutely intrigued as to what this would be manufactured into.

  • Do you believe that this may be what they use in newer stage lighting?

  • as you can see, you can see nothing 😂 such powerful led, i also want one of those

  • Now lets see that heatsink set up on a CPU. Change the fan out though. I'm sure anywhere around 2-6 fans in various arrangements could be set up.

  • Damn you make these look easy. I need some electronic training desperately...

  • The sun simulator that they have in space is one large LED light bulb which creates heat like our sun and wave lengths of light like our sun too.

  • For highspeed camera work this light would be amazing!

    • toysareforboys my pfp is also easy on the eyes. cockatiels. yay.

    • That would work well yeah. Shouldn't be any flicker if powered with the voltage regulator as it is filtered on the output.

    • Why would I want to look at my ugly mug every time I leave a comment, sign into my youtube account, etc. Also she is bat shit crazy, she's a little easier on the eyes than me :)

    • Thanks for the detailed reply Jeff. Is there a flicker issue even though he's running it on DC not AC?

  • The Photography that can be taken with that at night is gorgeous because of the "natural" contrast

  • Do they use those lights for stage lights? I think the cost of it seems what it’s meant for.

  • "I'll make a sun with this LED !" Nuclear Fusion had left the chat...
