I want something like this! Light up the whole yard and I wont have to stop filming just because the sun went down.

Impressive! I built a 1.6kW myself a few months ago, and I had to abandon the lenses because of that yellow circle. I thought it was an optical "stretch" of the light with the higher angle of refraction on the edge, but thanks a lot for the tip! Also, how did you fix the lens holders in place with the lenses like that? Thanks! :)

I remember a guy at a 'party' that had an inverter the size of a small fridge in the back of his mini van, it was running an old arc light from a theater. the huge light was mounted to the roof racks and it was rated at 20 K. The inverter was on fire and I told him, he didn't seem to worried as this was happening periodically. He did put the fire out, but did not stop running the light.

Is it possible to get the fluid TOO cold by using ice, etc?

4:40 watching the water go was really cool! but then again this whole thing is pretty cool.

Now you have the power of the sun in your garage. Cold winter day? Fire up your lights, get your lawn chair, and lay back with a drink.

How are amazing! Respect!! :D Greetings from Spain

Derpy Hoves never wore her safety goggles, now she doesn't have to XD

A few things you might want to think about Water wetter, it's not a type of anti-freeze, but it breaks down the surface tension of water, improving heat transfer Also, by chaining the water blocks like that, some array's will be getting hotter then others, possibly significantly so. Sections of copper tubing in the straight sections could help add some additional cooling and help with the sagging issue if your ever running those cooling lines again in the future.

Nice start to a killer grow room.

This is insane! In a wonderful kind of way :D Love it! Nice to see people out there making practical innovations and putting together tech in new and interesting ways. Keep up the very interesting innovations! You've earned another subscriber. :)

Is it just me or is watching the water rush through the tubes calming?

Ok, you've officially sent one of your prototype cams to everyone of my favorite youtube channels. I shall take a gander and sub.

Using manual exposure and then turning the LEDs off, leaving only the normal celing lamps, was a good idea. It really made it clear how wild those LEDs are. Cool stuff!

Awesome video, great project. The IIHS video was fascinating too. Also your cat is adorable. :3

Fabulous. This is why I love the internet. And thank goodness there are people like Tesla500 doing this stuff so I don't have to.

just read a bunch of new articles about your camera! awesome stuff, hope is is a huge success!

Thanks. That was fun to watch.

750kW of incandescent lighting in the automotive safety lab. That's just crazy amount of light!

Stainless stencil would be good for the masks

YOU ROCK MAN!! Liked and subscribed!

awesome work buddy WOW

great video man! i love playing around with LEDs too! thanks for the tip about the ring matte!

bro your invention could be soon adopted in stadiums lightings. 10/10, you're the best.

I love how the normal florescent shop lights look so dim with the LED lights on. The camera is stopped down so far that the FL lights look burned out! Very cool.

Seriously great work man. I'm envious of your sun beam!

Make yourself a little supply and return manifold so the cooling blocks are piped in parallel. I promise you that you will not be disappointed with your temperatures. Great build!

I admire your set up, layout, and workmanship. Most excellent. One feature you must add is the use of coolant instead of water. Should drop temperature about 15%. For 5KW, that is an outstanding array. I rigged a similar array for my wife in her art endeavors. I'd guesstimate 2 to 4 times incandescent power requirement for the same coverage. Here is a trick for you. We needed full or modified spectrum of color in her studio. I painted the entire ceiling with the entire spectrum rainbow. Then reflecting some of the light off the ceiling, six 500 watt portable halogens in my case, we could add some or all of the color spectrum as desired. Absolutely fantastic for getting to proper skin tone and color of the models regardless of their natural skin color.

excellent light and excellent camera.......it handled the light perfectly

what collimator lenses are you using ?.

I would be interested to see if you get any 'phase banding' or 'flicker' from these lights when shooting at very high frame rates for slow motion, have you shot any tests yet?

where dud you get the domes covering them?

AMAZING VIDEO!!! ;)

LOVE your videos!!! Great Work! Discovered you from Cody's Lab

amazing... thanks for share

LED's are cool... but I love the tech behind the Vortek arc lamp... that thing is insane.

Thumbs up for the setup and thumbs up for Trixi. :3

What do you have to do in order to modify the golf cart battery chargers be LED drivers? Are you just using an off the shelf 1k dimmer to dial down the voltage to dim the light?

Nice done,

Very very nice job!!! And kudos for doing all the appropriate measurements! But how do you plan to evacuate air bubbles out of all that tubing?

Did you use thermal paste to seat the Leds? Also, would coolant (for a car radiator) not be better than water?

Do you have flicker issues when dim the light? Do the LEDs flicker at high frame rates or fast shutter speed / shutter angle?

The idea with the masking is pretty neat. I have to try this. Have you measured the actual temperature directly at the led in this setup? A water temperature of 70°C is pretty high and even while your led mounts seem really good, the leds are probably getting a bit too hot for long term operation.

this is awesome

oooh what an exciting lightbulb :) :)

Love the cat :) and nice lighting setup

Great test set up. The charring of the cut out indicates of a lot of heat in the LED chips. Keep up the good work.

God this is Beautiful and so AWESOME!!!

Great video my dear friend!

Did you think about using special coolant instead of water for example that used for PC cooling?

Are you overclocking the led lights? I have never seen a water block and cooler attached to a light before.

Nicelly done sir, you are awesome.

Bring it on! Too cool.

I am trying to put two 150w LED chips in an old theater Fresnel fixture. My main concern is cooling. I was thinking of grabbing two Corsairs H55 to to cool both chips but I have no clue if it will be enough. I will be using two Luminus CVM-27. They operate at 4200ma/36V/150W and have a Thermal resistance of 0.16 ℃/W Do you know if the H55 will be enough to cool?

Did you realise you are probably the only guy in the world having a water cooling installed in his garage ceiling ?

i work in a theater with stage lighting. i'm pretty sure this light you've built is brighter than all of our stage lights put together.

came for the lights, stayed for the cat

How did you go about the thermal overload protection?

Awesome!

pawsome build

You could use that setup in a large venue to help people who suffer with Seasonal Affective Disorder (SAD for short), it's as bright as a sunny summers day, that's a given!! :D

How did you wire the individual LEDs? 2 parallel circuits of 5 in series?

Where did you buy this leds and lences?

you win.. good job

The future of stadium lighting right there in your garage. Very impressive.

Wow, that's impressive! Maybe an aquarium chiller for the reservoir would be a good next step

excellent. You need the high power *light for the high speed camera, right?

Way cool, man :D

Well done! Funny to think about how much energy it takes to make a bright sunny day..

Does it pulse at your AC supply? If you're doing high speed isn't this an issue??

I like to only be a Patreon for my top 3 favorite channels but I went to check your Patreon out and I cant believe you only get $39 donated to you casue (SO I had to throw a few buck your way, keep up the cool videos) ... I love you tear downs and even more your builds like this....

Can this be made into two rows of leds 50" long with the water cooler behind it powered by a 12v car battery? If so I would be interested in trying to make a light bar for my jeep that would be brighter then the HIDs lights I'm currently using.

why u connect water lines in series?

I am impressed :-)

That was impressive! Those floureschent lights in the ceiling look like they where off - and those usually give off quite much light compared to "normal" indoor lighting. I also know those tube halogen lamps of 1 kW - now think of LEDs thats so much more efficient. Each module is like 5-6 times that light, LOL! Perfect for high speed filming.

Looks good. Make sure youre treating the water in the loop to prevent nasties from growing. Thatll be one hell of a mess to deal with if you have to pull it all apart and clean everything:)

Did you connected the LEDs in a module in parallel or in seriell? I assume its parallel

This is one of the best looking "super" led builds ive seen. I just finished making one this week but mines only air cooled and runs one 100w led

Nice!

06:00 the cat, lol

What sort of pump are you using?

Luke from linustechtips in 5 years time

NEAT. i like it

derpy never wore her safety goggles... yessss 6:03... omg you named your cat trixie :D

what sort of thermal compound did you use between the led and the housing it's sitting in?

Neighbors probably thought there was some UFO alien shit going on in that garage.

wher can I get this 1kw or 5kw led modules

If your application is for filming only, you could evaluate synching your camera shutter with a control circuit, which will enable (open) the current to the LEDs only when needed (24, 30, 50 or 60fps) and at a duty-cycle (DC) of your choice. A few opto checks will setup the DC for each shot. That will save a considerable amount of electrical power without compromising the light levels perceived by the camera sensor. You've done a remarkable project. My regards

You blinded me through the interweb!

you deserve wayyyyyy more subs sir.... And that camera will change the face of youtube.

Your cat at 6:00 was like "I'm Blind!!!"

Since the coolant lines are hooked up in series wouldn't the module on the end get very little cooling?

Now just hook it up to the slab heating in the floor. Awesome video man.

"Derpy never wore her safety goggles. Now she doesn't need them!"

lol youve got some fancy lighting equipment XD

where you got the lens?

So this is how you got all those Slo Mo vids with your cam....That cam was awesome btw....I wish I could be an intern in your garage,...lol...im not joking btw

Monstrous setup and light output. What do you use it for?

WOW its Bright !!!!!!! i like

u dont u use copper pipe if its going to be permanently(well nothings permanet) installed in the ceiling?:)
