hi all. I have been using a k2 lamp in my aquarium for a year, and I was pleased with the purchase of k3. mode set lps, no change in power, at night the light is off. a week has passed and the channel A (white) is always on, barely visible, does not respond to the remote control (0-100%), it seems to shine at 5%. what should I do? Is it possible to buy a repair kit?
