DIY 250W LED Flood Light for High Speed Filming, Part 2 of 3.

This is part 2 of my diy led flood light that is going to be used for high speed video filming with the FPS1000HD camera. It should be able to deliver around 20000-25000 Lumen.

Here I modify 3x HP server power supplies to deliver 36VDC, add fan controllers for the heat sinks and box it all up in a “very compact” box that can be handheld.

It is being built form 5x 50W LED COBs mounted on old Pentium4 CPU coolers.

I got no affiliation with these sellers, but it is where I bought my parts:
