yeah but im a student i have to study all the time, my girl friend is the real palnter, hps is a little bit complex for her, i mean there are some components of it just like ballast and the big lampshade to decrease the tempreture, once these stuff dont work she cant deal with it, my most worried thing is the high tempreture which may cause a fire, you know you cant always belive a girl 100percent, led is much easier and safer but my question is what the difference of the yield between led and hps? is it a huge number?
