Metal Halide lights
This is a real newbie question, I'm sure. I have been looking at indoor lighting, because I have a lemon tree, but I live in a basement apartment, and get very little light. The lemon is not thriving. All the metal halide bulbs are reasonable priced, I think. But with the ballasts and cords and reflectors and whatnot, they end up costing so much money!
So what I'm wondering is: can you plug a metal halide bulb into a regular socket? If not, is there any converter out there so I don't have to buy the whole shebang just yet?
