Quick Product Snapshot

Lamp and Design Breakdown

The T5 HO (High Output) format delivers more light per inch than standard T8 lamps, making it an efficient choice for reptile enclosures where space and output consistency matter. The 2.5 UVB rating is calibrated for shade-level UV environments, replicating the filtered light conditions found on forest floors and in shaded microhabitats. UVA output supports natural reptile behavior, while visible light contributes to a natural day-night cycle within the enclosure.

Setup and Compatibility Guidance

This lamp is designed for use with Zoo Med's existing T5 HO hood lineup. Install according to the hood manufacturer's instructions. The 12-inch length is suited for compact and mid-size enclosures. Replace the lamp within 12 months to maintain effective UVB output, even if the lamp continues to produce visible light beyond that period.

Care and Maintenance

Replace every 12 months to ensure continued UVB effectiveness. Handle with care — avoid touching the lamp surface with bare hands during installation. Clean the hood reflector periodically to maintain optimal light output.
