I have 2 Ecotech Radions above my 55 reef. Both are gen 1 and have not been having any issues. Starting yesterday, one of the two began fading on and off as if it it were to turn itself on or off. It continues to do this for the entire span they are on until lights out...with no issues with the other light. I've cut the power to give it a reset without resolution. I have not updated any firmware or changed anything to them at all. Any ideas?
