damage damage damage, don't waste your time with that lamp. That is a halogen lamp and will fry your plants...can you afford to buy lights necessary to grow?...If on a budget inside sun.com is selling 250 hps for $80, there is always e-bay I bought a 400mh and 250hps for $60 ea., and last, but not least, you can get 45w cfl's at wally's for $9 ea., but you will need 4-6 of them, they screw right into a regular light socket...hope that answered your question.peace, latewood
