This ceramic heat emitter 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. Specifications: Base:E27. Voltage:AC110V. Material:Ceramic + Alloy. Color:White. Diameter of heating surface: 125mm(Approx). Wattage:25/40/50 60/75/100/150/200/250/300W. Heating source: Ceramic, infrared, electrical, no light emitted. Features: Tolerates high temperatures from reptile heat or light bulbs. Tough ceramic sockets won't break down in heat stress. The black exterior finish is powder coated and fired for added luster and long life. 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. Note: Surface temperature is too high, do not directly touch during use. Package Included: 1 x Heat Emitter Bulb
