The Roux Array
Completely custom build with the best materials and professionally assembled to last for many years to come. This is the prototype to 3 more I am building like this. Using the ladder/rack style build for this type of project.
Frame
Simple, elegant, functional. 19" heavy duty custom aluminum heatsinks. 39" long 3/4" angle aluminum at 1/8" thickness. M3 taps were made to attach the LED strips to the heatsinks and the heatsinks to the rails. This will provide passive cooling necessary for the LED strips, it will be able to dissipate the heat even if the driver is running at 100%.
Driver
Even though this light is capable of 600+watts. I went with a 480 watt adjustable driver Meanwell HGL-480H-24A. It has 2 Vo outputs because of the load on the wires, it needs to split the total load. Added a 5 foot AC power cable (14awg 3/c) and plug (125V 15A), and 7 foot DC power cables (16awg 2/c) with waterproof quick connectors.
Wiring
Customized my own wiring harness for the light array. 16 awg bus with 6x 18 awg soldered T junction power connectors for each positive and negative. Each power connector has been tinned with solder for the best connection when sliding into the LEDs power receptacle. Waterproof quick connects were soldered on and the total wiring harness has been affixed to the light array with zip ties.

I’m excited to try out the S7 chips. This light array will break through to the 200+ Lm/W. I did some power calculations to get an operational range of 197 - 210 lm/w (46,800 - 91,800 lumens)
