Delivers UVA and UVB radiation to support calcium metabolism and natural basking behaviour
25W daytime lamp with E27 base fits standard terrarium fixtures without additional adapters
No ballast required — direct mains connection simplifies setup and reduces equipment costs
19.4 cm lamp length and 0.123 kg weight make it lightweight and easy to position in compact terrariums
What sets the Exo Terra UVB100 apart
Unlike standard daylight lamps, this unit is specifically engineered for reptile husbandry with a balanced UVA/UVB output calibrated for tropical and desert species. The E27 base ensures compatibility with the majority of common terrarium light fixtures, and the 25W power level delivers sufficient UV penetration for moderate terrarium depths.
Ideal for...
Reptile keepers maintaining tropical or desert terrariums for species such as bearded dragons, geckos, and iguanas. The lamp is suited for setups where a dedicated UVB source is needed alongside a separate heat source, as the lamp itself does not emit significant heat.
Application of Exo Terra UVB100
Install the lamp in a compatible E27 fixture positioned above the terrarium
Maintain a distance of 10–15 cm from the basking spot for optimal UVB exposure
Replace the lamp every 6–12 months as UV output degrades over time even if the lamp still appears to glow
Pair with a thermostat-controlled heat source to create a proper temperature gradient
