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 :)

Not sure what your budget is, but why not something like three MeanWell HLG-480series, or six ELG-240 series? These supplies are passively cooled and designed to run at 100% output all day long.

I suspect the power supplies were overloaded because the total power they can produce and the total they can produce in a single rail are two very different things.

You can buy a 20 quid ferrite transformer core from Amazon, and wind 6 secondary coils, one for each power connection, and use common diode rectifier bridges with a 100 micro farad capacitor (smaller for higher frequency, high tech power networks) , and it would be 1/8 the size, and cost of that ghetto mess you made.

I'm a bit late watching this one, but I suspect the LED used is almost identical to what Mole Richardson made for their 1600W LED Tener. www.mole.com/tener-led - At my last job we powered these massive air-cooled LEDs off batteries using a Dewalt flexvolt 1800w power station. The whole kit ended up close to $20,000 CAD but was almost perfectly silent and the most portable solution available! FYI 4x 9.0ah batteries = ~25 minutes at 1600w

Using air based heatingsinks is slightly problematic. Very often your cooling water starts to accumulats "stuff" from the inside of the radiators and pipings. This can start to block the small fins and cause some channels not to get enough fluid throughput and cause localized overheating. Removing some of the fins should solve this. Check your lamp with a terminal camera for hotspots. (This effect takes month/years to manifest)

every thing put aside...i like your sun glasses
should you not have water tested for leaks first before committing to mounting the led on it? btw why not have direct water cooling over the entire led using distilled or deionized water so no issues with electrical shorting but more efficient direct heat transfer?

The reason I believe power supplies failed is because when you were running them at max power the components inside power supplies got quite hot and as long as the fans were running the temperature remained under the limits but as soon as you may have pulled the power plug the fans, and the power supply turned off but the heat inside the supplies was accumulating as there was no way for it to wick away quickly as the fans are off at that point and the components got super hot super quick which resulted into failure of the supplies.

You need to have 3000 Watts of Supply with a clean output. LED's also are better with a Pulse Driver so its not Linear Driven through time 100% all the time. at 60FPS youll never notice a flash, but it will be flashing. they cant or at least SHOULDNT be drivven at 100% Load... you need a Time Limiter Circuit and run HUGE capacitors between the Supplys and the Driver Boards (which are PULS WITH MODULATED) you CANT run them ALL the time... Only Fractionaly... Actually, you can run them directly off the AC line with a V divider and a Bridge Rectifier ...I'm from a different dimension so my terms aren't gonna be the same. Maybe. I may be kidding... still not sure
