Yes I love my Leds best thing since sliced bread. I am in a different situation to most because of the size of the tank and the budget I was limited to what I could afford but as it turned out after much research I got very good lights!!
I was having trouble with 10 x 250watt metal halides over the tank causing extreme heat, all last winter the heating didn't come on and the chiller ran much of the day.
The purchase of the Led lighting has turned the problems with heat over the tank around now the chiller hardly comes on. I have had them for two months now and the coral growth and colour is still good, the viewing is much more pleasant and the fish love the sunrise - sunset affect all done by the control boxes.
The other plus is it is going to save a fortune in electricity and the annual change of 10 metal halide bulbs and 8 artinic bulbs every 9 months!!!!!
If anyone wants some metal halide lights I have some forsale :slfg:
