Ceramic heat emitters emit invisible infrared radiation which warms animals and objects. This heat radiation allows to create warm spots in which the animals can "bask". Thanks to the invisible radiation, ceramic heat emitters can be used 24 hours a day. Their long life makes them an economic heating solution. Attention: Ceramic heat emitters create a lot of heat and should only be used in higher terrariums (80 cm and up) with enough distance to the animals.
