Step 13: Halogen Lighting
Halogen lights are also used in reptile enclosures. Like fluorescent lighting, they produce less heat than incandescent bulbs. Unlike fluorescent lighting, halogen lights can be dimmed, meaning that they are acceptable for use with a rheostat.
Halogen lights usually have two pins in the bottom and need to be used with a proper halogen lighting fixture.
They are available for daytime and nighttime use. Make sure that the type of halogen light purchased provides the enclosure with the proper amount of UV light. Monitor the temperature of the reptile enclosure to determine whether or not additional heating devices are necessary. And as always, if a halogen lighting fixture must be used within a cage, make sure that the reptile cannot climb on it.
