Reptiles rely on external heat sources to elevate their body temperature. Zilla Heat Mat Terrarium Heaters provide warmth for reptiles to absorb from their surrounding environment in order to maintain and thermo-regulate heat used for daily activities, appetite and digestion. Carbon fiber heating technology efficiently radiates infrared waves creating uniform heating with no hot spots. Carbon fiber is an energy-efficient method for heating with no wires that might become pinched or broken. Each unit has adhesive backing and is low voltage with a maximum temperature of 113F. The material properties restrict it from getting warmer and remove the need for a thermal switch, which often fail.
