If you want a nice 250 watt light, this is what i use right here. The digital ballast allows it to use either a 250 watt MH or a 250 HPS bulb, so the choice is up too you. It also runs very quiet, cool, and isnt too bulky.

if you wanna go a little cheaper here is another system, its just not brand name like the Lumatek. It also has a digital ballast so you can run both Mh or HPS. Its a killer deal though, the cheapest 250 watt i can find. i would be suprised if you can find a better deal.(and if you do show me!!! i wanna get one too)
