I have a RGB+W COB LED that I want to turn into a custom aquarium light for my aquascape.
I'm wondering what Driver I need to buy if I want to be able to independently dim any given LED group on this COB (Red, Green, Blue, White) to customize the end result coloring for the light. Do I have to buy 4 dimmable drivers (one for each color) in order for this to work or are there drivers out there that have multiple channels for dimming? This project would be powered by Mains voltage. Should I be looking at Constant Current Drivers for this application?
I also don't have an issue underdriving the LEDs to cut down on heat and extend lifespan. I don't necessarily need the full 100W capability advertised if that helps my situation at all. I assume the 800mA used in the tables below is for the max rated output of the COB?
any input is appreciated, thanks!
