Testing the World’s Most Powerful LED, Or: How to Fry Two Power Supplies

Matt at DIY Perks recently got his hands on a monstrous, 1500W, single LED that he believes to be the brightest and most powerful single LED unit in the world. But actually getting this thing to work without blowing up or burning itself alive… that’s not so easy.

The LED in question is this 1500W, $1,350 monster from YUJILEDS, and there are two main challenges to actually powering this thing up: cooling and power delivery.

In terms of cooling, Matt built his own custom water block for the LED using an old copper heat sink that he converted into a water tight container using brass plating.

To cool the water, he’s using not one, not two, but four 120mm x 4 radiators stacked one on top of the other, which are then connected in a loop to a reservoir, two water pumps, and his custom-made water block that was fitted to the LED. This should, in theory, serve to keep the LED from burning itself up as soon as it gets any real power.

That takes care of cooling. As for power, Matt had to find a way to deliver 1500W and 30V to the LED without overloading his power solution. His initial setup included two sever power supplies wired in series to provide a total of 2000W of power at 24V. He combined that with six voltage boost boards in order to not just meet, but exceed the needs of the LED on each of its 6 power section.

All that was left then was to power on each individual section … and put on two pairs of sunglasses. This is what it looks like with his hand covering the LED:

Everything worked as expected—the cooling solution in particular performed VERY well—but unfortunately, the power supplies he was using burned out before he could take the system outside. For whatever reason, maybe because they were wired in series, the two 1000W power supplies just couldn’t handle the 1500W that the LED needed to draw without overheating to the point where smoke actually started coming out.

Check out the full video up top to see the test for yourself. And if you want to see the follow-up once Matt gets his power supply issues fixed, be sure to subscribe to DIY Perks.

Canon Unveils Key EOS R5 Specs: Dual IS, 4K/120fps, No-Crop 8K, and More

Canon has released another round of specs for the much-anticipated EOS R5, revealing several compelling reasons why this camera is set to be the most revolutionary Canon product since the debut of the 5D Mark II.

The news is being released during today’s livestream press conference, a quarantined version of the announcements Canon was originally planning to make during NAB 2020. In addition to some expected announcements about cinema cameras and lenses, Canon is taking this opportunity to release its third (and final?) “development announcement” about the EOS R5, revealing just how powerful of a video camera this thing is going to be.

Previous teasers announced the camera and confirmed a few key specs: like no-crop 8K video with dual pixel AF, IBIS, and the addition of “advanced animal autofocus.” Today’s announcement dived into the nitty gritty, revealing some game-changing video specs and a few important updates for stills shooters:

  • Internal 8K/30p RAW video recording
  • Internal 8K/30p video recording in 4:2:2 10-bit C-Log and HDR PQ
  • Internal 4K/120p video recording in 4:2:2 10-bit C-Log and HDR PQ
  • External 4K/60p video recording over HDMI
  • No-crop 8K and 4K video recording using the full-width of the sensor
  • Dual Pixel CMOS AF available in all 8K and 4K recording modes
  • C-Log available in 8K and 4K internal recording modes
  • 5-axis In-Body Image Stabilization works in conjunction with Optical IS in both RF and EF lenses
  • Dual-card slots: 1 CFexpress and 1 SD UHS-II

For video shooters in particular, this update is nothing short of mind blowing. On raw specs alone, the camera seems to outperform even high-end cinema gear like the $39,000 full-frame Sony Venice, which maxes out at 6K/30p and 4K/60p, both externally recorded.

We’ve yet to hear a catch from Canon. Initially, people thought we would see a significant crop, or no Dual Pixel AF in 8K, but neither of these theories panned out. The most common concerns now have to do with heat dissipation: will this camera overheat in minutes while shooting 8K or 4K/120? And if not, is there some extreme recording limit in either of these modes?

We’ll have to wait and see, but the more we find out about Canon’s upcoming 5-series camera, the more revolutionary it sounds. Still no word on pricing or availability, but you can watch Canon’s livestream right now, and keep up with all the EOS R5 updates and teasers at this link.
