Install AND adjust terrarium lighting in seconds. An R-Zilla Clamp Lamp is the easy way to position healthy light or essential heat in a reptile terrarium. A heat-resistant ceramic socket and black reflector dome are designed to accept R-Zilla's strongest incandescent heat or light bulbs (rated up to 150 watts). Installation is a snap: simply attach the large gator clip and bend the flexible gooseneck to aim light. The six foot power cord comes with a handy rotary itch. Bulb not included.
