Philips makes excellent quality lamps. For $9 you can't go wrong. The only thing I could say bad about that lamp is that it's probably not optimized for growing. Doesn't make much of a difference tho.
tyler is correct Phillips do a great job, making good shit cheap, but thats it!! 200w Mh is just to small with too much heat....go for a min of 400w, and get 9 plants under in 3 gallon pots to 3 ft high in 3 months
