oh ok you need a ballast and the housing for the light bulb, i see what you were asking now, your asking how do you do all of that. i thought you meant how do you hang it in the closet. i would say return the bulb and get a grow light or at least a light and ballast. they also sell ballast kits online if you are comfortable with electrical wiring and such. like i said they dont cost too much for a bigger better light that is ready to go. search ebay and look at hydro stores and see whats best for you.
