The 24 inch Zoo Med ReptiSun T5-HO Terrarium Hood is an affordable and incredibly effective light fixture designed for use in sensitive reptile terrariums. Its sleek, barely-there profile makes it an attractive and non-obtrusive addition to your custom reptile enclosure, allowing the focus to remain on the exotic and visually stunning inhabitants of your tank. The ReptiSun Hood features an energy-efficient T5-HO electronic ballast to guarantee rapid starts and maximum lamp performance and provides exceptional UVB, UVA and visible light for your reptilian friends. A highly polished curved reflector is also incorporated to significantly boost light and UVA/UVB output and the high output T5's are perfet for larger and taller enclosures to ensure essential UVB penetration is provided at greater depths. For convenient manual control, an on/off rocker switch is mounted on the rear of the hood. Alternatively, the ReptiSun T5-HO Terrarium Hood can be used with a light timer of your choice (sold separately).
