The Energy Savers Reptile Combo-Light is a fluorescent and incandescent combination light fixture designed to maximize the benefits of both types of lamps. This allows for the use of a full-spectrum UV emitting fluorescent lamp along with incandescent full-spectrum daylight/heat lamps and/or incandescent nocturnal/heat lamps.

Hobbyists can create an ideal lighting environment for their terrariums. The Reptile 20" Combo Light is a three-lamp light fixture designed to accommodate one 18", 15 watt fluorescent lamp and two incandescent lamps up to 150 watts each for 300 watts total. Available in 20", 24" and 36" sizes.
