You would need leds to go with those though. JK JK That would be crazy.

What did you decide on?
The main units people use for SPS are: t5, MH or LEDs. T5 can create some sick colors with so many bulb choices. MH are tried and true but do create quite a bit of heat. LED are kinda the new guys on the block but have been proven very successfull and are pretty energy efficient. Plus they dont transmit as much heat either. I dont think you could go wrong with any of these though as long as you purchase a quality fixture. Best of luck!
