I made these 2 fixtures that fit on a 20, 29, or 37 gallon tank. I ran one of these on a 29 gallon with rose bubbles for 2 years, and they did great. Each has a meanwell driver/power supply. One has 2 fans, and the other has 1 larger fan. 3 watt cree royal blue, and 3 watt luxeon cool white. $25 each, or $40 for the pair. There are some diy parts that go with these - 2 extra cool whites, and 1 extra royal blue.View attachment 4007.
