Reptile ceramic heat lamp emits natural heat without any light, so it won't disturb the sleep of reptiles or pets. Adopted material into ceramic raw materials, thermal efficiency can be up to 99%.The reptile heat bulb is perfectly 24-hours radiant heat source. The high-strength ceramic shell makes the heat concentrated more on the surface of the ceramic disc. It can work for 15,000 hours of continuous work or more, with a long-time service life.Spiral surface design means longer filament, increases the filament resistance, expands the heating area, and increases the filament temperature in short time. The nickel-chromium alloy resistance wire increases the heating speed and heat dissipation area, and reduce energy consumptions.The ceramic heat lamp is high thermal-efficiency, energy-saving and power-saving. The heating speed is fast and stable, and the heat is balanced and lasting. Do not touch the bulb with your hands to avoid being burned.Ceramic heat lamp is made of high-purity pottery clay to ensure its anti-crack and work in high humidity terrariums. Solid ceramic components are waterproof and explosion-proof,suitable for high humid environments.Colour: BlackMaterial: CeramicPackage Contents:2 x heat lampOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
