Me and Mr. Binford both have converted over to leds. I have a all softy tank and I had T5 lights My softies love the new lights and the color is awsome. I had no issues changing. Mr binford did lose some things but he has alot of SPS and we learned that you need to start low and work your way of brighting the lights now his corol love the light. I have seen a big change in the electic bill to instead of a $300.00 we now have it under $200.00 It was well worth the change
