Feature: Good heating effect, but it does not issue stimulus light affect the animal sleep . Impact resistance, can contact with water, uninterrupted heating 20000-50000 hours. New technology, the thermal efficiency is up to 99%. Emitted far-infrared can preserve heat, at the same time, animals have excellent health care. Emitted natural infrared thermal, does not emit light, it will not disrupt the normal cycle (day / night). Solid ceramic component suitable for wet environments. Ease of installation, coupled with ordinary ceramic lamp base, then spin on. Specifications: Base Type:E27 Power source: 25W/50W/75W/100W Voltage: 110V/220V Material: Ceramic Color: Black Size:55mm(h)x45mm(dia.) Note: Surface temperature is too high, do not directly touch during use. Package Include: 1 x Pet Heating Lamp Heating source: Ceramic, infrared, electrical, no light emitted. Solid ceramics element has a good heat radiation feature (also works in sealed box) Non Light Emitted: Compared with other lighting lamps, no light, emits a natural sun-like infrared heat. Neither interfere with the animal's natural rest, it will not interfere with people. Features: This emitting heater provides 24hours constant heats for reptile's environment. Perfect for High Humidity Terrarium: High strength ceramic package element, suitable for humid environments. Increase 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
