The Exo Terra Reptile UVB100 T5 VHO Bulbs are recommended for use in conjunction with the Exo Terra T5 Terrarium Top High-Performance Reptile UVB Fixtures to provide optimal results and prolonged lifespan of the bulbs.

Exo Terra’s exceptional T5 lamps are crafted in Germany to the highest quality standard, ensuring a prolonged UV output of 12+ months for lasting performance. With their intense output of UVA and UVB rays – combined with a well-balanced visible light spectrum – the Exo Terra Reptile UVB100 T5 Very High Output Bulbs are specifically designed to meet the needs of reptiles, amphibians and invertebrates inhabiting the Cryptophotic Zone. The intensity of the emissions varies depending on the distance from the basking area.

Appropriate levels of UV are vital for the physiological wellbeing of these animals, which exhibit an aversion to direct solar exposure. Typically known as ‘shade dwellers’, these animals have adapted to nocturnal and crepuscular activity – opting for either deliberate or concealed exposure to sunlight.

The Exo Terra Reptile UVB100 VHO T5 Bulbs help promote healthy Vitamin D3 synthesis, which in turn facilitates improved calcium absorption – safeguarding against Metabolic Bone Disease. The UVA and UVB emissions surpass those of traditional T8 bulbs and energy-efficient alternatives, while enhanced UVB penetration extends the suitability for use in taller terrariums or those equipped with denser screens.

Keepers can use the UV Index reference values to ensure that animals are exposed to an appropriate level of UV when basking. Creating a gradient – from highest safe UV index at the basking area to lowest UV index in cooler areas – means they can completely self-regulate alongside their thermoregulatory behaviours. They should not be allowed to expose themselves to more than a safe maximum and should have the freedom to escape all light completely with areas of zero UV and Infrared. This can be achieved by strategically adding plants, hides, and decorative items to create shaded zones.

To support the efficient conversion of vitamin D3 and enhance various metabolic and hormonal processes, it is beneficial to ensure that UV light exposure is complemented by an ample supply of infrared-A (NIR) radiation. The most effective sources can be found in Tungsten Halogen or standard Incandescent Spot Bulbs, such as the Exo Terra® Intense Basking Spot or Halogen Basking Spot. This combination promotes optimal body temperature regulation and overall well-being.
