The Zoo Med Mini Combo Deep Dome Lamp Fixture is designed for use with basking lamps, UV lamps, and heat lamps. It combines two fixures in one for maximum convenience! It is contructed with extra long reflector domes that extend beyond the face of the lamps, preventing the lamps from “sticking out”. Features include: ceramic sockets designed for use with lamps up to 100 watts (per socket), polished aluminum domes for maximum light and heat output (increases output by up to 30%), and independently controlled in-line on/off switches for greater convenience.This product is NOT designed for use with ceramic heat emitters. 11″ x 6″ x 7″
