ok i would like to know the difference between a 400 watt hps and a 400 watt halogen im guessing the hps would be better but also should i even use 400 watt in like a 3' 10' closet or should i use 250 watts
 
the problems of halogen are three - wrong spectrum, inefficient light per energy used, and excess heat.

they are the worst kind of light.
