    FAQ Time! But first, don't forget that after your first two months of free Skillshare trial goodness it's LESS than $10 per month if you go with an annual plan, which is like a good cup of coffee per week but instead you're building on your lifelong knowledge. Enjoy! skl.sh/diyperks2 Now, question and answer time! The first think I'll say is that there's been a surprising spread of discussion about various aspects of this build in the comments. It's great to see! I actually learn a lot from reading comments that you guys leave, and there are some serious golden nuggets of info here and there which I appreciate a lot for building on my own knowledge. I will first address a few common misunderstandings though. Firstly, some folk are assuming that the LED is 90%+ efficient, which would mean that it would only output 150w as heat and the rest as light. This isn't the case unfortunately, as even some of the best LEDs are only 40% efficient MAXIMUM. This figure changes depending on the colour accuracy, with more colour accurate LEDs being less efficient as they have to emit more of the visible spectrum. Let's assume the LED is roughly 30% efficient (which is probably fairly accurate, and may even be a bit generous) that means that 450w is being emitted as light, and the other 1050w is being wasted as heat. So, I built my cooling system around the assumption of needing to dump 1000w of heat into the air, which is why I had four large radiators and made an extreme cooling block for it. LEDs last longer when they're cooler, so it's super important. I also want the final unit to run quietly, not with maximum fan speed, so this extra headroom allows me to do that. Another thing that crops up is talk of corrosion. In water loops it's very important to use similar metals, otherwise you run in to galvanic corrosion where one metal will literally steal electrons from the other, causing the other one to corrode quickly as they're 'connected through the water'. Brass and copper are similar enough, but the lead in the solder may be susceptible to corrosion. However, adding an anti-corrosive additive to the liquid should solve this in the final build. The radiators are copper, not aluminium, so no worries there. As for the PSU's failing... there have been many theories but nothing solid. They are 12v PSUs, and are rated for 83A on that lane. When in series, they give 24v at 83A... 83*24=1992w. The reason for my wanting a higher voltage is that it literally halves the amps on the voltage booster, meaning they can run easily rather than at their absolute maximum ratings. Hit me up with any more questions! Anyway, I hope that clears things up. If you still see these questions popping up please relay the answers contained here for me please :)

    Nice work! Apologies for not scrolling through all 5,000+ comments to see if anyone has suggested this application, but here's one I'd love to see: using this for a high-power stroboscope. Lower-power LED modules (eg 10W) great for this. I built one with 2X10W modules that gets regular use in my shop. Runs off a 20V DeWalt tool battery and provides very crisp 60 micro/second pulses. Only downside is that they're relatively dim, which limits the range of the scope and requires a relatively dark room. 1500 Watts would make you the new Doc Edgerton. How you switch that much current that quickly is way beyond my pay grade, but you seem up to the challenge. Hope you take it on!!

    I think one good way of demonstrating how bright this is would be to have that turned on outdoor over an object in the daylight, against the direction of sunlight, so that one can see how far from the object the LED would out-brighten the sunlight as the reference.

    They look to be HP DL380G5 series powersupplies ! 12.15V / 82.3A is on the label ... So you think they would be able to handle this when cooled properly... Reason they freak out is because the boost converters are switching power supplies as well, peak currents will be a lot higher. That 1kw is rated at resistive load...

    Just for reference, leaving this LED on for 5 minutes uses more power than if you left your microwave on for 5 minutes, that's what "a lot of power" means in this context. Also for reference, if you were to leave this thing on for 8 hours of the day for a month (like you would some normal light), it would cost you around 5376p, or 72USD. Better hope it's the only light in your house.

    Idk where you get that leds are efficient in that regard, I believe it depends on how they are driven. I do think however that this cooling solution was meant to be overkill, ie, this is not a production version but a prototype and it was meant to spare the oh so expensive led. This was pretty obvious from watching the video.
