Provide the necessary warmth and light your reptile needs with Zilla Basking Bulbs. These bulbs are easy to use for any reptile terrarium and feature heavy-duty filaments that yield more hours of service from every bulb. They provide heating and lighting that create natural daytime conditions in the enclosure and serve as an ideal heat source to help regulate your reptile's body temperature. Zilla Basking Bulbs are available in four colors: Day White, perfect for reptiles requiring bright, naturalistic daylight such as bearded dragons, iguanas, and other diurnal species; Day Blue, ideal for enhancing color vibrancy and promoting plant growth in habitats with tropical and desert reptiles like chameleons and geckos; and Night Red and Night Black, which are best for nocturnal setups where maintaining low light levels helps simulate natural nighttime conditions. Recommended for use with Zilla Reflector Domes. For extended use, avoid contact with water, limit frequent on/off cycles, and allow the bulb to cool before handling. Celebrate your pet and Rep Yourself, with Zilla.
