How'd you end up driving it? Did you use PWM? I'm not too familiar with all of the capabilities of the RKE. It does look like a great controller but hopefully I can use my Raspberry Pi to build something comparable. It's great to hear that quite a few people are using those same kits. I would probably have something fabricated from TAP Plastics to cover those drivers/dimmers. We did the same thing for Brandie's tank for the circuit I built to run four 140mm fans within her canopy to cool off her two 250W MH's. Yeah, I was basing my price comparison to the brand name LED lights. For the same price as those cheap Chinese ones, I definitely think a DIY kit would be better. That RapidLED light measures 6" x 9". Not sure if that'll provide enough coverage?
