Has anyone had any experience with cree leds before? They have a unit which is the 60 watt(each led is 3 watts) and it has like 20 bulbs, the whole unit is roughly $400.00..i dont want metal halides too much heat and alot of electricity use..the cree has 2 adjustable knobs for the blue lights and white so you can have the perfect lighting you want anytime. Was wondering if this system would support a clam? And be worth the money..i know for sure Im going to have LEDS for my main lighting eventually..im trying to find the best. Thanks all!
