Reptile UVB300 T5 Fluorescent Lamp 54W by Exo Terra for Terrariums

Exo Terra Reptile UVB300 T5 Fluorescent Lamp 54W is a purpose-built UVB light source for terrariums housing reptiles that require low-to-moderate UVB exposure. The lamp delivers a controlled spectrum of ultraviolet B radiation from a compact T5 fluorescent tube with 54 watts of power. It is designed to be installed in compatible T5 fixtures above basking and activity areas to support natural behaviour and physiological processes related to vitamin D3 synthesis and calcium metabolism.

Advantages

This 54W T5 lamp offers a stable UVB output appropriate for many diurnal reptile species kept in captivity. Its form factor and wattage provide broad surface illumination while maintaining moderate UVB intensity to reduce risk of overexposure in species that do not require high UV levels. The lamp is made to fit standard T5 fixtures used in terrarium setups and integrates with existing heating and lighting elements without altering color rendering or visible light balance significantly.

Suitable for

• Terrariums with reptiles needing low-to-moderate UVB (e.g., many geckos, skinks, and small lizards)
• Enclosures where even, surface-wide UVB coverage is desired
• Setups combining UVB with separate heat sources and daylight lamps

Key specifications

• Type: T5 fluorescent UVB lamp
• Power consumption: 54 W
• Emission: UVB spectrum designed for reptiles (low-to-moderate intensity)
• Fit: standard T5 fixture compatibility
• Form factor: slim linear tube suitable for placement above basking zones

How to use

Install the lamp in a compatible T5 fixture positioned above the terrarium so the UVB output reaches the animals' primary basking and activity areas. Ensure proper distance between the lamp and animals according to species-specific needs and fixture recommendations; avoid placing the tube behind thick glass or opaque covers that block UVB. Operate the lamp on a regular daily cycle that mimics natural daylight hours, typically 10–12 hours per day, and combine with appropriate heating elements to provide a thermal gradient. Replace the lamp according to manufacturer guidance or when UVB output declines, even if visible light remains acceptable.

Usage recommendations

Monitor animal behaviour and calcium metabolism indicators (feeding, activity, bone and shell health) and adjust lamp distance, photoperiod, or lamp type if clinical signs of inadequate UVB or overexposure occur. Use in conjunction with dietary calcium supplementation and routine veterinary checks for best results.
