I also have bulbs for every purpose. Right now, I'm just using 25W and 40W bulbs, but I have 8, 11, 25, 30, 35, 40, 50 and 60 Watt bulbs and at least two or three of each.
I don't know how i managed to collect so many types, but I've used terrariums with heights ranging from 25 to 80cm. I've just used them for heating.
