So, my old T-5 4bulb unit failed. I decided it was time to stop changing bulbs and go all LED. I had been using two actinic blue 55watt panels...plus the 4-55watt T-5's. My old panels were early models. The white was terrible, so I did not use it. They were also not dimmable. So, the new unit is 2 dimmable panels from DsunY. It was originally a 1 plug unit. I paid $20 extra to have it made into a 4 plug unit...so, the blues and whites can be on separate timers. They even have a special controller that can mimic sunrise to sunset with the dimming feature. I did not want this option. I am very happy with the lights quality. My big issue was it's configuration. The plugs and knobs are on the sides. So, it was very difficult to put them in my cabinet. The legs from the company were AWFUL!! Do not buy them to use these lights. They are really better off as a hanging system. I managed to use the legs from my T5's and stagger the units..one higher and one lower. But..now they are in, I am really liking the look of my tank. ALL LED...done buying bulbs.
Here are the ones I bought
