Update: finally figured it out.. but wondering if I need 1 of them repaired. The fan starts getting loud and then light eventually turns off, assuming from overheating.
Bought a tank over a year ago that came with these lights. Plugged them in and they worked. Now I've done something to the controller and I cant for the life of me get the lights to work again. It originally had a ton of color available and now it's just blue and white. I think I just updated the firmware successfully but I'm clueless about the rest.
