Exo Terra Reptile UVB100 T5 Fluorescent Lamp 24W 55cm for Terrarium

Exo Terra Reptile UVB100 T5 Fluorescent Lamp 24W 55cm for Terrarium is a specialized T5 fluorescent tube designed to provide controlled UVB radiation for captive reptiles. Engineered for placement in terrariums, the lamp emits UVB wavelengths that help reptiles synthesize vitamin D3 and support proper calcium metabolism. The 24 W, 55 cm format fits common T5 fixtures and is intended as a supplemental UVB source to complement ambient or artificial heat and visible light in the enclosure.

Advantages

The lamp delivers a stable and predictable UVB output suitable for a wide range of terrestrial and arboreal reptiles. Its T5 format provides a higher surface output than larger tube types at close distances, allowing effective UVB exposure when installed at recommended heights. The product is manufactured to be compatible with common T5 ballasts and fixtures, offering consistent light quality and long operating life when used according to specifications.

Suitable for

• Supplementing natural sunlight for diurnal reptiles in indoor terrariums
• Supporting vitamin D3 synthesis and calcium metabolism in species prone to metabolic bone disease
• Enclosures where a controlled, diffuse UVB source is needed at moderate distance from basking sites
• Hobbyist and professional setups using T5 fixtures compatible with 55 cm tubes

Key specifications

• Type: T5 fluorescent UVB tube
• Power consumption: 24 W
• Length: 55 cm
• UVB output: controlled spectrum optimized for vitamin D3 production (manufacturer-specified UVB curve)
• Intended use: terrarium UVB supplementation for reptiles
• Compatibility: designed for use with T5 ballasts and fixtures

How to use

Install the lamp in a suitable T5 fixture or reflector positioned above the terrarium at the manufacturer-recommended distance to ensure appropriate UVB exposure to the animals. Operate the lamp on a daily cycle that mimics natural daylight hours, typically 10–12 hours per day for most diurnal species; adjust duration based on species requirements and seasonal needs. Replace the tube according to the manufacturer's recommended service life or if UVB output declines, since visible light output can remain while UVB emission decreases. Always ensure electrical connections and ballasts are compatible and switched off before replacing the tube.

Usage recommendations

Use this lamp as part of a comprehensive husbandry setup that includes appropriate heat gradients, hide areas, substrate and dietary management; measure UVB irradiance at basking locations with a UVB meter where possible and adjust the fixture height to achieve species-appropriate levels.
