Zilla Pro Sol Fixture with Timer. The newest technology in reptile lighting is here – customizable Heat, UVB and UVA all in one! The Zilla Pro Sol Fixture combines functionality and modern design in one small, low-profile package. This sleek slim fixture has multiple heat sockets which allow for a 24-hour hot basking spot while also creating an essential smooth heat gradient both horizontally and vertically in the terrarium. The fixture also comes with a separate night socket which allows you to individually control day and night settings to replicate a natural day cycle for your reptile. Fully customize the Pro Sol Fixture for a Tropical or Desert environment using Zilla Mini Halogen Bulbs for heat and Zilla Mini Compact Fluorescent Bulbs (not included) for UVB/UVA. Accessory clips are also included for quick and easy mounting above a terrarium.
