I bought a 48" sat+ 2 or 3 years back and got 2 36" sat+ fixtures for Xmas of 2013. About 3 weeks ago 1 36" started blinking on and off, tried a power supply from the other 36" fixture for an hour and all was fine so I ordered a new power supply. After 2 days with the new power supply the problem returned. Last night the 48" fixture started doing the same thing. Has anyone else had this issue? I love the light they provide but I don't have a lot of confidence in the company right now. My tank is 72"x30"x25"(LxWxH) and I'm towards the buildmyled.com 72" fish focus fixture, but I'm open to suggestions.
