20"X22"X53" - Proper Lighting?

What would be the proper lighting for a 20"x22"x53" space? This is a wardrobe closet so theres not much room for expansion.

Was thinking a 150-250w HPS?

yeah man you should be fine with even a 150w. Just make sure you line your walls with m,ylar and use a reflector. in that size of space you concentarate all of your light in that small of an are so you should be golden with a 150...hope it helps.

Ohh you forgot this....

I think this needs to be recommended more often. Have fun! Good luck.
