Features: 1.This ceramic heating light bulb is the perfect 24 hour heat source for all reptiles 2.Tough ceramic sockets won't break down in heat stress, durable 3.High thermal efficiency, the non-light heater lamp will not disturb animals sleep pattern 4.The black exterior finish is powder coated and fired for added luster and long lifespan 5.The bulb is made from glass containing rare earth black phosphors, which simulates the moon's natural glow for nocturnal viewing without disturbing the reptile's day/night cycle Specification: Description: This ceramic heating light bulb is the perfect 24 hour heat source for all reptiles. These porcelain heating devices screw into a standard porcelain incandescent socket, giving off intense muscle-penetrating infrared heat while emitting no light. The flat-faced design is more efficient and longer lasting than conical designs which build up excess heat internally ultimately carbonizing the element. Features: Tolerates high temperatures from reptile heat or light bulbs. Tough ceramic sockets won't break down in heat stress, durable. High thermal efficiency, the non-light heater lamp will not disturb animals sleep pattern. The black exterior finish is powder coated and fired for added luster and long lifespan. The bulb is made from glass containing rare earth black phosphors, which simulates the moon's natural glow for nocturnal viewing without disturbing the reptile's day/night cycle.
