DocBrown86 Posted December 13, 2014 Share Posted December 13, 2014 I have a CMB24 DC board and 4 - 20W rgb floods that I bought from Amazon. For some reason, 3 look the same on the inside and 1 looks different. I need to verify some voltage questions: The triplets: Have led driver boards rated 24-36V. 2 wires travel to the front where there is a small circuit board which branches out into rgb and black to the respected colors, with a separate, different resistor per color added between the circuit board and the light. When on full white, each color reads 17V DC. On one at a time, red gets 20V, green is 14V and blue is similar to green... So if I used a power supply for the board, which voltage do I set it at?? And do I just unhook the driver board supply and not use it? The solo light looks the same, but no circuit board. Just goes from a 12-24V led driver, out of it in rgb and black, to the light. On full white voltage varies from color 20V red, 14V green and 12V blue. Link to comment Share on other sites More sharing options...
