Exo Terra Reptile UVB 100 Compact Lamp 26W (PT2187)

The ET Reptile UVB 100 Compact Lamp 26W is a compact fluorescent UVB bulb designed for tropical and sub-tropical reptile keepers. It replicates the moderate UV conditions found in rainforest and tropical environments, where canopy cover, humidity, and variable weather naturally filter sunlight before it reaches reptiles at ground level or in shaded basking spots. This is a direct replacement for the former Repti Glo 5.0, now with an updated spectrum.

UVB Output and Spectrum

This lamp produces optimal UVB levels calibrated to match shaded tropical environments, with an effective UVB range of up to 40 cm (15 inches) from the lamp. The optimised Vitamin D3 yield index supports consistent D3 photosynthesis, which in turn aids calcium absorption and helps prevent metabolic bone disease — a common and serious condition in captive reptiles kept under inadequate lighting.

UVA and Behavioural Benefits

Alongside UVB, this lamp emits UVA radiation, which plays a role in stimulating natural appetite, activity levels, and reproductive behaviour in reptiles. Many keepers underestimate the importance of UVA; for tropical species, its inclusion in the vivarium light cycle contributes to overall wellbeing and more naturalistic behaviour.

Compatibility and Pairing

• Suitable for all tropical and sub-tropical reptile species
• Effective UVB distance: up to 40 cm (15 inches)
• Can be paired with a full-spectrum natural light or reptile vision lamp to improve overall visual light output in the vivarium
• Compact form factor fits standard E27 compact lamp fittings

For any tropical or sub-tropical species where moderate, consistent UVB provision is a core husbandry requirement, the ET Reptile UVB 100 Compact Lamp 26W delivers a reliable, well-matched spectrum without the need for a full linear tube setup.
