Warm Your Reptile Without Light
Ceramic heaters don't emit any light and are one of the best ways to offer heating to your reptile. The porcelain bulb does not affect the day/night cycle as it does not product any visible light, and emits in such a way that blankets the terrarium evenly. Ceramic heaters do tend to reduce the humidity in your terrarium, so they are best used for desert species.
The surface of the bulb get's very hot, so it's essential to use a cover to keep your pet safe.
All types of heaters should be plugged into a thermostat to more accurately control the temperatures of your enclosure.
