IMPORTANT NOTE: do not use over 100w bulbs inside any fixtures mounted on the inside of the enclosure. not only do you not need more then 100w per socket but the excess heat may cause issues with ceramic fixtures like the one shown directly below. do not use ceramic heat elements in either light socket shown here. do not use Mercury Vapor Bulbs greater then 100 watts NO exception. do not use mercury vapor bulbs in this type of enclosure for frilled dragons 18-24 inch uvb 10.0 by zoomed or exoterra will be sufficient and even save you money if you buy your fixture from walmart, and your bulb from amazon.com
