Exo Terra Reptile UVB100 T5 fluorescent tube 54 W for terrarium lighting

Exo Terra Reptile UVB100 T5 fluorescent tube 54 W is a purpose-built lamp for reptile terrarium lighting. The tube delivers a consistent spectrum with UVB output appropriate for many diurnal reptiles that need UVB exposure to produce vitamin D3. Designed to fit T5 fixtures commonly used in enclosures, this 54 W lamp supports physiological processes such as calcium metabolism and normal activity patterns when installed at the correct distance and used with suitable reflectors or fixtures.

Advantages

The T5 fluorescent design provides stable UVB emission across the tube length and works with standard T5 housings and reflectors for even light distribution. With a 54 W output, the lamp produces sufficient irradiance for medium to large terrariums when positioned according to manufacturer guidance. The product is intended to combine UVB emission with visible light output to create a naturalistic day cycle while supporting vitamin D3 synthesis in reptiles.

Suitable for

• Diurnal reptiles requiring UVB for vitamin D3 synthesis and calcium metabolism
• Medium to large terrarium setups with T5 fixture compatibility
• Enclosures where even, broad-spectrum lighting is needed alongside UVB

Key specifications

• Bulb type: T5 fluorescent tube
• Power: 54 W
• Function: UVB emission suitable for reptile use
• Form factor: Linear tubular lamp for T5 fixtures
• Light output: Combined visible light and UVB spectrum for day cycle simulation

How to use

Install the Exo Terra Reptile UVB100 tube into a compatible T5 fixture with appropriate reflectors to direct light into the enclosure. Mount the fixture at the distance recommended by enclosure and species-specific guidance to achieve safe UVB irradiance; closer placement increases UVB intensity while greater distance reduces it. Use a timer or programmable lighting controller to provide a regular day/night cycle, typically 10–12 hours of light for most diurnal reptiles. Replace the tube according to the manufacturer's suggested service life or when measurable UVB output declines.

Usage recommendations

Measure UVB levels in the terrarium with a UVB meter to ensure correct irradiance for the species kept. Do not rely solely on visual appearance to determine UVB output; replace the tube after its effective service life even if visible light remains. Combine UVB lighting with appropriate thermal gradients, hiding spots, and dietary supplementation as advised for the specific reptile species.
