Imagine trying to sleep and your neighbor turns on the sun
😁😁😁
Well I can no longer laugh at some of my options for an opening statement for the wasteland survival guide.
I need 1000 of them housed in a giant DiscoBall for the Ultimate Grow Light!
Relatable
I find this comment quite amusing.
British man got tired of the shitty weather in england, creates his own sun

Trevor Noah if it makes such a racket how do you use it as studio lights or anything for that matter
You use it to grow weed man😂

Liquid cooling 👍
Electric bill $2000 - see what l did there?😆 tuff audience tonite 😏
Well just get a heatsink for a AMD threatripper, its actually pretty much the same size and they r only around 50-150 bucks, i mean they only rated for 200W CPUs but im pretty sure a LED has a way different efficiency, so it wont even give off that much heat as a CPU does
Husband: "Is that a UFO? What IS that?"
Wife: "The neighbor got a new light again..."
lmao
2:57 " And as you can see, We can't."
Everyone from my area uses these as headlights, I swear...

A fake sun.
Okay i will come back for that.
"The power of the sun ... in the palm of my hand"
Sort of... As it's actually trying to mimic the Sun's effects, specifically making artificial light seem like natural light in a video. I'm not so sure that there are not cheaper ways to achieve that.
Me to... will come back for fake sun too, wonder if it can be used in some way to test / prove that our real sun is not 93mil miles away on globe earth hoax theory. Damn, now i need fake earth...
This guy is such a pretentious twat. Jesus Christ what a pathetic video I cant believe I just wasted those minutes of my life that way.
LED's can hear and hurt your eyes and brain. Solar panels in space. Look into it, don't just react.
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.
You should see how many flashlights I have, and my collection is minuscule in comparison to others
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.
@@travispratt6327 I Googled 15 years old forum posts and some people were modifying incandescent lamps just like people now are excited about LED COBs.
Very nice comment.
I was browsing Reddit and found r/flashlights , pretty cool and wholesome subreddit
scientist: how many lumens you want?
me: yes
I guess this is the LED Fractal Design will use as the power indicator in their next computer case...
Very funny!
I know those feels! 😂

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

You could make a grid array out of them, a custom water block and water cool those fuckers. Then you'd really have your own sun. But at that point if you sit in the ray even with the back turned the light would shine through your head and still reach the eyes.

@JS 09 whats the perfect temperature?
.
@@albine6103 27c
bitterman co he means the temperature not spectrum , that thing emits heat like a open fire
@@Katana666D Nope the temperature that is in question is the "Kelvin" of the light, which is 3200 Kelvin.
Many 100W COB grow lights are at 3500 Kelvin and do a great job, at producing you daily greens.
As for the heat from the unit, that is dissipated by the heat sink and internal fan and the residual heat in the grow space is removed by an extractor fan, as it is with all grow setups.
Efficiency wasn't talked about but when you increase the brightness of the COB up to the max 440W shown in the video, the less efficient the light to heat ratio is. The more power you pump into a COB LED, the greater the percentage of that input power, is turned into heat and so making the COB LED's light output less efficient.
500W is nothing new for single COBs but one this small is amazing and it is really quite an achievement to produce one at this size but the heatsink is still huge and noisey.
For a few years now it has been possible to buy a 2400W COB but the chip is huge and so too is the heatsink.
2400W COB can be found at Flip Chip Opto - fcopto.com/products/ along with a load of other large sized LED COB lights for general lighting, grow lighting and broadcast lighting.
Remember if you have never grown under COB LED or you know nothing about Kelvin scale, probably best not to say "it is not suitable temp".
If you think the unit is too hot to be in a grow space, just remember COB LEDs are more energy efficient than HID Bulbs, which is to say, if you can grow under 600w HPS then the heat given out by a 500W COB LED will definitely be cooler because a COB LED it is more energy efficient than an HPS & so gives our less heat and it also use 100W less power draw than a 600W HPS.
Many growers use 600W HPS (old skool growers & commercial grows, although this is changing and more efficient lights are being used more often now) and the growers deal with the heat from those lights, so why would a 500W LED COB light be too hot temperature wise???
I would also advise those who don't know what they are talking about go have a look at Growmau5 and Migrow videos and learn a thing or three, before wading into waters too deep for them to keep their head above water!
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.
I thought the same
FinnishArmy no LED flickers its not good for slo mo video making
Not really, dc wont do that. Thats ac.
@@user-lq1dk6gr3p 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
@@user-lq1dk6gr3p LED does not flickr, however if you apply pwn, the power supply does.
I had no idea a $500 led even existed. Thanks for sharing!
AdventureSportFlashlights That was the ONLY reason why I watched this.
growing weed its common to use $1000+ led
not usually for a single led
Tyler, never does single led diode go higher than about 12 watts with current tech. However COB style led (many small diodes running in parallel), like the one in this video currently go upwards of 2000 watts. A particular brand of grow lighting Helios makes a 1500 watt single cob led light. Flip Chip Opto makes the wafer itself

*And that's how he vaporized the sun*
poppet pala The sun basically is vapor. It's plasma, which is just ionic gas, or gas where the electrons move around like crazy, like running a current through metal.
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.
2:46 *So I'll continue increasing the voltage until I blind myself*
Imagine losing it
Edit: oh wait it’s huge
JoneTech Yep, I got the same thought until I saw the heat sink..
Id still manage to lose it somehow
Daniel Auen so , have u ever lost a desktop PC?
A desktop pc, Dont think so, 1/5 scale bright yellow hummer rc, yes. Ive lost my printer twice, Ive even lost a 15 inch crt tv! My desktop computers are usually making too much noise to get lost, also, they are generally giant, my smallest pc right now is a dell optiplex 755, its in my living room sitting in a cat tree right now. well, for smallest it would have to compete with my alienware x51 that I loaned to a friend a few years ago. actually now that I think about it, I did manage to lose a few HPs a few years back, I think one was a hp dc7800 and I dont remember the other one. I think I even managed to lose a chainsaw at one point.

Video is so bright I put on sunglasses to finish watching it

Even my sunglasses had to wear sunglasses.
I'm now ledburnt!
My phone screen lit up so much it almost hit 500W of output
TAKE THAT!!! ... Atomic Beam!
5:05 thanks you answered my question I was absolutely intrigued as to what this would be manufactured into.
Nice! And Definitely stay for the cleverness at the end of this piece.
Love that shadow thing at the end.
NOICE!! Your future looks bright. Literally.
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!
“Small area”
Fan: am i a joke to you
3:12 Wow, it's so bright that one tree woke up and said "is that the sun, mate?" The other tree replied "nah, that's our evening cup of tea again. That's very common here" That LED is awesome!
worlds lamest attempt at dad humour ever
Yeah it's cool but he was full of crap, that thing isn't as bright as the sun. The sun is several hundred degree's and thousands of miles away from earth and still brighter than that thing. I'm pretty sure no LED will ever be much more than half as bright as the sun. /end trollhat
Bloody hell, my Imalent DX80 must be close to 400w and it's a handheld Flashlight with hardly any heatsinking!!!
Try Leaving it on for 20 minutes and then touching it
The Imalent one uses 8 CREE XHP70 LEDs right? Total power for that would be 230w max. Insane for sure, amazing indeed, but it also enters termal protection at 50°c exactly because the body itself is a heatsink.
You would not be able to hold a 500w heat source in your hands for much long, it would sure need a heatsink with fan, maybe not as extreme as shown (and working with PC cooling, I would say, YES it needs it).
Hmmm.....I wonder how good is that heatsink on a CPU.....
Well that LED puts high-end work station CPU's to shame in power output, so...
I thought the same thing
Unbelievable! Its bigger than any CPU heatsink I've ever seen which is to be expected since A 500W CPU would be very inefficient. I think the highest wattage CPU is 140W.
Simon Tay Doesnt mean it would be an insane cooler for a 140 watt cpu, even crazier on a 95 watt
TheJoJmaster diy adapter
You could probably build an amazing projector out of this, using the LED as the backlight
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.
A dollar per watt?
That's shit.
WAAAAATTTTT???
More about cri and efficiency. Although for $500 you could get 10 cree cxb3590s.
wavefront101 but they wouldn't be anywhere close to a single point source.
Well it's 24,000 lumens so think of it as about $0.02 per lumen. Each dollar gets you 48 lumens
You're voice is so calming. Like I had this video running in the background of my web browsing and it really calmed me down. Lol You should consider reading books or doing podcasts.
Lee Fesler Do you know Tom Scott's channel? His voice is somewhat similar and his videos are also very interesting
His voice has always annoyed me slightly - he sounds exactly like childrens TV presenters from the past. I'm sure he just sounds like this, where as they were purposefully adopting a calming/condescending tone.
His content is great and I'm sure he's lovely, which is why I'm still here! :)
Maybe he is on some meds. Look at those pupils!

This light will be good for photography.
Another great informational topic! Thanks!
well that’s my Pentium 4 heatsink looks like. i can sell it for you for $350 if you want
Lol it's what the fans in a Pentium 4 system sound like too
yep those sucks. louder than my mom’s freakin hair dryer
Happy Torrent AFAIK they consume 500-550W under load, so even a bit more than this LED.
id sell it for 100$ and it would be the best deal of my entire life
it is called a joke, and you myfriend just ruined it
It's almost like having the sun right in the palm of your hand!
Primeval Media Peter cat
Was that an Otto Octavius reference from Spider-Man 2? Or maybe I've just been re-watching those movies lately
Neighbours called. They were wondering why the sun was in their eyes.
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!)
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.
danteelite I’m not sure how legal this can be
@@AlejandroS-mh5gm 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.
@@Hoch134 Yeah, though I assume it isn't really good since you may damage other drivers eyes
BUT CAN IT RUN CRYSIS?!
Kamiel Brees I was waiting 4 this
It’s an LED, not a computer, what do you expect?
its sarcastic
Kamiel Brees I know, I was being sarcastic too
Yes, if you swap out the fan with noctuas youll probably get 3 or 5 more fps tho
Now he can go safely to the bathroom *in the dark nights :-)*
I am happy for him !
Great review! Cool LED!
if you focus the light from it into a point - will it burn the wood?
1:59 Would be fun seeing someone using this as a studio light, with that loud fan. HELLO GUYS TODAY IM GOIN.........
IKR all future videos will have to be dubbed. :p
ii think with a watercooled system would be possible
oh, watercooling a LED now....
for reference a threadripper 1950x (one of the hardest processers to cool) only uses 180w, and stays at around 60-80c under load with a 240mm radiator
this light uses 440w, it stays at 40-50c using the heatsink.
Zhao Zhao just liquid nitrogen cool it, it's silent and it probably won't die when water condenses around it like on a CPU
He could give it the same CPU heatsink/Noctua fan treatment he gave the GPU in his silent PC.
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!
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.
I feel really bad thinking about Ramsay Bolton when I masturbate. Just had to get that off my chest.
I liked the ending. Thanks for the video ^^
Is it good for filming if its that loud?
Probably not. I think the next upgrade would be new fans and a temperature controlled fan speed.
Maybe water cooling would solve that.
I don't think you would have something that bright close to your mic.
For vlogs it would be unideal, but if you film something on a professional basis, you are synchronising audio anyway.
If you are a DIY kind of person, (which if you watch this channel I assume you are. You should buy the LED without the heatsink, and swap it out for a large PC air cooler, or maybe water cooler. although the really good quality PC air coolers have similar performance to water coolers while also being quieter because they don't need a water pump. I would put a Be quiet! darkrock pro 3 on it, First off because it would look bad ass, but second because it's dead quiet and should provide equal performance to the "stock" cooler.
came for the title. stayed for the pole dancing at the end
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?
I love how genuinely happy he is in this video 🙈😹
10$ Led 490$ heatsink
Ozmayne nope.. 10$ for LED + heatsink 490$ for shipping..😄
Ozmayne - Heatsink option is $70.
was gonna be my exact comment.
Pretty much
Ozmayne not really the heat sink would be realatively cheap... Think of the LED as a CPU. very small but huge amounts of engineering has gone into it...
imagine using this as the lamp for a projector
navid mehdi
That will guarantee that your business meeting is alive and awake!!
I was thinking of that too.
navid mehdi imagine 1000 of these as a replacement for the sun at night.
I'm a theatrical lighting designer and this is very fascinating technology to look at for me. Could be ideal for stage lighting.
It would be interesting to see how you can utilise this light as a projector setup light
can i get that heatsink :D i want to oc my 8700K
DIY Tech idk if it would be enough XD
JonnyTaunton if that is the case then could a CPU heats sink like a noctua air cooler could keep the LED cool?
Hmm, now that I think about it, I think someone would need a heatsink 3x as large to OC an FX-9350 xD
What u guys think about Thread ripper :D
DIY Tech it's da bomb !!!!
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!!!
Sounds interesting! Did they have a black grid of material in front of them too?
The only problem is that with such high CRI and power output they aren't much more efficient than a xenon light source. So you won't see them everywhere.
This is an interesting approach, however it is good only when there is a need to create space universally lit by the "sunlight" (just like in a sunny day outside). Very good for the photo shooting when there is a need to mimic the daylight in an open space.
Inside the confined space like a living room, however, i wouldn't consider this as a good approach. Having single 500W it would be much better to create a "sun rays coming though the window' illusion, which lights only the space where the rays fall, and the rest of space is lit by the ambient lighting. You can play with the rayleigh scattering and optics to create an "window with a sunny sky behind it" casting a single, yet powerful ray with no diffusion. Just like in a sunny day inside the house.
+Nick Bobrov I am a photographer, director, producer and screenwriter
NO your the janitor that's what's up
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.
Yeah that also looks like the only thing I can remember about any car advertisement -a brief shot of the car then a long close up of the headlight on high beam
wire them up to your car headlights and blind every person who has their high-beams on....
atleast that's what I would do

Robin Inget Why would he destroy a 500$ 500W premium LED?
Maybe he just put it back together? He looks like a handy man, and oh, I like my men handy and sweet like candy.
He probably edited out the green pcb
It's connected to the PCB in two points. It's not a big deal. You can clearly see it's the same diode.

SAS Productions Dream Market for sure
I'd like to incorporate this idea within a terrarium. Thanks for posting!
Imagine these as street lights with a gradual increase & decrease in brightness synced with sunrise and sunset 😍
@@biackshibe lmfao
Nah, I do street lights, and putting a COB as a main source of light is cheap and stupid. Why? Of course it will light up the area, but at the cost of blinding people and lighting a very narrow area. What you'd need is an array of less bright LEDs with well designed optics.
we couldn't see the sun anymore
Just one problem if you're going to mimic a sun with it; This outputs 5600K light, although direct sunlight is warmer than that. What you need is the 3200K version of this for direct sunlight, then a 5600K version that fires up into the roof and diffuses down as skylight.
Skylight is the blue sky itself that is diffused and scattered everywhere, while sunlight is the warm direct light from the sun, coming from one direction. Combined these will create a realistic effect. Take a look at this video that explains a bit more th-cam.com/video/aJ4TJ4-kkDw/w-d-xo.html
Although a cool project, can't wait to see the results!
They do make a 3kK version,
but at these prices, a pink reflective card might have to do :-)
You know nothing about the sun. Get off TH-cam you feeble-minded, ignorant poser.
This seems like the kinda thing that well look back on and laugh at how primitive we were cause theyll only cost like $.30 in the future, like how we do now when looking at those giant old computers that fill an entire room and can only do basic math.
Carlos Hernandez maybe in 200 years

More like 0.00000003BTC
Those still exists, now they're mostly servers
Build a machine that can mechanically compute latitude and logitude based on speed and trajectory. That is small enough to fit on a plane or submarine then say it's primitive.
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.
Not a dumb idea at all.
High pulsating current reduces led lifetime significantly
It burns so bright! Great video I now feel like my retinas are shot. :)
For highspeed camera work this light would be amazing!
toysareforboys That depends on the diode's, and power supply's, operating frequency. Lights built for high speed work have electronic ballasts that control sine wave of the power delivery resulting in a flicker free image. Without this ballast every multiple of the hertz frequency would cause a dim frame. Shooting at 60fps with a standard incandescent bulb on 60 hertz house power results in a dim frame every 10th frame.
toysareforboys why is there a woman in your profile picture? those arent allowed in this clubhouse.
Thanks for the detailed reply Jeff. Is there a flicker issue even though he's running it on DC not AC?
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 :)
That would work well yeah. Shouldn't be any flicker if powered with the voltage regulator as it is filtered on the output.
Bloody Stark arc reactor right there!
"I'll make a sun with this LED !"
Nuclear Fusion had left the chat...
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.
The LED with 5600Kelvin has between 20.000 and 24.000 Lumen. At 12A and 35V - 39V (420W - 468W) this are only between ~42,7 and ~57,1 Lumen per Watt.
With other words I think this LED is dump and you should spend your money in a different way.
where did you get this data?
The most stuff is on their website, the rest is physics and math ;)
yea sorry just found the description. although this seems way too low efficacy. i usually work with 140lm/w high bays. well they have loe colour rendering as well. i'll check on some nichia and bridgelux chips now.
But I really have to say I don't need this high ammount of watts on only one COB.
Convert that to a projector!
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 !
"Look how small it is" With 40 lbs of gear next to him lmao
"Congratulations Mr. Stark, you have created a new element"
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.
"im just going to undo these so we can have a closer look." voids warranty
does cooling gets better when we add thermal paste between that LED-chip and the resting place of that chip?
Yes, that is a must
Sorry to disappoint you, but this LED only has about 22000 lumens, or roughly 50 lumens per watt. So it's extremely inefficient, even when considering the CRI of 95. For comparsion: The Cree CXB3590 with CRI 92 provides 13237 lumens at 86 watts, equalling to 153 lumens per watt.
And they cost only 30 €. By mounting two CXB3590 on a CPU cooler, one can make a light which is brighter, cheaper, smaller, less noisy and less power consuming than this 500 watt LED module.
Those LED's you're mentioning max out at 90 cri so probably lower than that... the colour is what you're paying for here I guess!
what about the XHP70.5 arnt they the most efficient and brightest? I think they sell for 10 bucks each
Yeah that's not too efficient. Plus it pulls 12 amps. Damn that's alot for just 500 watts. I can run 6 citizen cobs off a meanwell hlg 240 and get over 20k lumens with a little more than 2 amps and 250 watts. 70 for the driver and 8 dollars for each cob plus the heat sink. Way cheaper than 500
It us alwaya like this when you are pushing toward tech limit you lose efficiency in application and price per unit, so I dont think it as a dissapointment.
Video: "This is useful in applications that require a concentrated light source... Stable color temperature... Is a lot easier to focus the light from a single, small, source than from a big surface... Etc."
Comments: "Ahaha... How stupid are you!... Just pack a lot of cheaper leds toghether!"
Needed a Welding Cap to see this video...
bas jansma I used this video and magnifying glass over my tablet to create portable welding machine.
Mika Korhonen loool
bas jansma I just finished what you started. :)
You have some really big pupils! Great LED btw.
Wow loved the trees at night that was crazy
That literally turns night into day. Police Helicopters could use this.
police Helis do use the same kind of lights, but they don't need near solar spectrum, bright white is good enough.
At first glance combined with the thumbnail I thought the title was "unboxing $500 LSD"
dagluke yeaaa
look at his pupils at 4:30... maybe some LSD was involved????
Someone is off his meds
this would work well for slow motion recording projects where there is a lot of light needed
