>>My friend is building an enclosure for her big iguana (she is about 5-6 feet nose to tail) The cage will be 6 and a half feet tall, 4 feet long and 18'' wide, how many bulbs should she get for the tank and what kind? Thank You in advance for helping

For most flourescent bulbs, you want to keep them no more than 12 inches from the body, so you would need to incorporate a few in there. These can be mounted under shelves easily. I believe Mercury Vapor is a bit farther away, but I do not use those.
