it will work. if i were u, i would get cfls they dont get to hot. and there great for growing indoor's. i would pick up about 6 100 watt cfls and u gonna get a good resault. plus ur not buying online. stick to flourecent bulbs. that alomst looks like a indecent light wich are a pain in the ass to grow with due to they create alot of heat wich can harm ur plants unless u have a fan in ur grow room. if ur gonna buy a bulb online id get a Hps (high pressure sodium bulb) good for the flowering stage of your plant! Good luck!
