Exo Terra Reptile UVB200 T5 VHO 8W 12" Vivarium UVB Tube | PT2426

The ET Reptile UVB200 T5 VHO is an 8W, 12" Very High Output fluorescent tube designed for reptile keepers who need reliable, penetrating UVB in a compact T5 format. Manufactured in Germany, it delivers a rated UV output lifespan of 12 months or more — making it a dependable choice for species that require consistent UVB provision without frequent bulb changes.

Designed for the Mesophotic Zone

This tube is specifically engineered for reptiles that bask occasionally or spend time in partial sunlight — a light environment referred to as the Mesophotic Zone. These species exhibit adaptive basking behaviour, balancing body temperature regulation with UVB intake while naturally seeking shade. Balanced UVA and UVB exposure is essential to their physiological wellbeing, and this tube's output is calibrated to replicate that natural solar spectrum. Emission intensity varies with distance from the basking area, so positioning matters.

UVB That Works Harder

The UVB200 uses a unique phosphor blend to replicate solar UVB output, with UVA and UVB emissions that exceed those of standard T8 tubes and energy-saving alternatives. The Very High Output rating gives this tube superior UVB penetration depth, making it well suited to taller vivariums or setups fitted with denser mesh screens that would otherwise reduce UV transmission.
