60 Watt Ceramic Heat Emitter.  Ceramic heat emitters project invisible infra-red heat into your reptile or birds environment to provide warmth both day and night without interfering with your animals need for a day and night light cycle. 

Be sure your animals can not come into direct contact these emitters as they get hot and could burn your pet.  Always use a light fixture that is rated for the wattage of the bulb or higher.
