Pics are too small. They are light bulbs, wire them up and move them around until you get the lighting you want. Also, making them movable is always helpful, albeit a little harder on initial set up. Can't tell if you have the outlets for the bulbs yet if not you can save a lot by getting them at the local Habitat for Humanity, i get the bathroom fixtures with like 6 bulbs in a row, typically less than $5 (the single outlet is $2 at home depot), have found for less than $1.
Love the avatar by the way. Good luck.
