ExoTerra Reptile UVB200 T5 VHO

The Exo Terra Reptile UVB200 T5 VHO is a Very High Output fluorescent tube designed for reptiles that bask occasionally or in partially shaded environments — what's known as the Mesophotic Zone. Manufactured in Germany across a range of sizes to suit enclosures of different scale, this lamp delivers intense, sustained UVA and UVB output alongside a well-balanced visible light spectrum that closely replicates natural solar conditions.

Built for Mesophotic Zone Species

Reptiles inhabiting partially shaded, dappled-light environments have evolved precise basking behaviours — moving in and out of light to regulate body temperature and UVB intake without overheating. The UVB200 T5 VHO is calibrated to replicate that sunlight-and-shade balance, supporting the physiological needs of species that require meaningful UV exposure without the intensity of open-desert or mountain-top conditions.

UVA and UVB That Goes Further

As a Very High Output T5, this lamp surpasses the UVA and UVB emission levels of standard T8 tubes and energy-saving alternatives. Enhanced UVB penetration means the lamp remains effective at greater distances from the basking zone, making it well-suited to taller vivarium setups or enclosures fitted with mesh or denser screens that can attenuate UV before it reaches the animal.

Health Benefits for Your Reptile

• Promotes healthy Vitamin D3 synthesis through UVB exposure
• Supports calcium absorption and helps guard against Metabolic Bone Disease
• UVA stimulates natural appetite, activity levels, and reproductive behaviour
• Unique phosphor blend replicates the solar UVB spectrum
• Designed for sustained UV output lasting 12 months or more

Practical Specifications

• Available in four sizes to suit vivarium setups of different lengths and heights
• T5 VHO (Very High Output) fluorescent format
• Manufactured in Germany to high quality standards
• Recommended for use with the Exo Terra T5 Terrarium Top fixture

Choosing the right size for your enclosure matters — select from the available variants based on your vivarium's length and the mounting distance from your reptile's basking spot. Whichever size you opt for, the UVB200 T5 VHO delivers consistent, reliable UV output that supports your animal's long-term health.
