I have two Red Sea LED90 units. They were purchased at the beginning of 2020. Over time both units have gotten noticeably dimmer with one of the units significantly dimmer than the other. I have tried hard resets to no avail. When I swap the power outlet cords, the dim light switches to the other unit. This appears to be a power outlet / supply issue. Anyone else have this problem? Solutions? Perhaps Red Sea will warranty this...I wrote their customer line asking for help.
