The Exo Terra Heat Wave Lamp is a radiant heat source and creates a natural sun-like heat with a uniform pattern. The long wave infrared heat produced by this emitter will warm reptiles very efficiently. It also increases the ambient air-temperature in the terrarium. Infrared heat penetrates the scales and skin tissue promoting health and healing as it widens the blood vessels and increases blood circulation. The Heat Wave Lamp is to be used only with the specially designed Exo Terra Wire Light. Innovative design 99% heat efficiency. Emits a natural sun-like infrared heat with no light emitted does not disturb normal photo periods (day/night). Solid ceramic element suitable for humid environments.
