Exo Terra Reptile UVB200 T5 VHO Lamp

The Exo Terra Reptile UVB200 T5 VHO is a Very High Output fluorescent lamp designed for reptiles that bask occasionally or in filtered, partial sunlight — what's known as the Mesophotic Zone. Manufactured in Germany, this T5 tube delivers intense, sustained UVA and UVB output alongside a well-balanced visible light spectrum, and is available in four sizes to suit enclosures of different scale.

Built for Mesophotic Zone Species

Reptiles adapted to dappled or intermittent sunlight rely on balanced UV exposure to regulate their physiology. These animals exhibit adaptive basking behaviours — optimising body temperature and UVB intake while managing shade to avoid overheating. The UVB200 is calibrated to replicate the UV conditions of these natural habitats, giving keepers a lamp that works with the animal's instincts rather than against them.

UVA, UVB and Vitamin D3

• UVB output supports healthy Vitamin D3 synthesis and maximises calcium absorption
• Guards against Metabolic Bone Disease with consistent, long-lasting UV delivery
• UVA stimulates natural appetite, activity levels, and reproductive behaviour
• Unique phosphor blend replicates the solar UVB spectrum more accurately than standard tubes
• UV output rated for 12+ months of lasting performance

Superior Penetration for Taller Terrariums

As a Very High Output T5, this lamp produces stronger UVB penetration than conventional T8 tubes and energy-saving alternatives. That makes it well suited to taller vivariums or enclosures fitted with denser mesh screens, where weaker lamps would fall short. Emission intensity does vary with distance from the basking zone, so placement remains important.

Compatibility

The UVB200 T5 VHO range is recommended for use with the Exo Terra T5 Terrarium Top canopy. The range spans four sizes, each matched to a different tube length and wattage — select the variant on this page that corresponds to your enclosure width and hood specification.

With German manufacturing, a 12+ month UV output lifespan, and a spectrum engineered around real reptile behaviour, the Exo Terra Reptile UVB200 T5 VHO gives keepers a dependable, biologically relevant lighting solution across a range of vivarium setups.
