The Exo Terra Reptile UVB100 is designed for reptiles that naturally inhabit shaded or low-light environments. These species, often referred to as “shade-dwellers,” are accustomed to moderate levels of UVB radiation, as sunlight is filtered through dense vegetation or cloud cover.

With its 3% UVB output, this bulb is ideal for creating environments where low to moderate UVB exposure is required. Supporting Ferguson Zone 1 and the Cryptophotic Zone, it provides the appropriate UVB levels for nocturnal, crepuscular species and shade-dwelling reptiles. The UVB100 promotes vitamin D3 synthesis, which is essential for calcium absorption, bone development, and the prevention of metabolic bone disease (MBD). This bulb is particularly suited for terrariums replicating shaded tropical conditions and works effectively when combined with naturalistic lighting setups. It ensures a healthy, comfortable habitat that supports the well-being and physiological needs of reptiles that thrive in low-UVB environments.

The innovative Sunergy™ phosphor blend sets Exo Terra’s Reptile UVB T5 lamps apart. Sunergy™ is a state-of-the-art phosphor blend developed using German precision technology to replicate the energy spectrum of the sun, particularly in the UV range. This cutting-edge blend comes closer to natural sunlight than any other lamp on the market and is designed to meet the highest standards, delivering unmatched quality and performance. With Sunergy™, Exo Terra’s Reptile UVB T5 lamps provide reptiles with the UVB they need for health, vitality, and natural behavior.

“The UVB and UVA2 spectrum is excellent – the most sun-like I’ve ever seen in a T5 lamp for terrariums – Thomas Griffiths of Tomaskas Ltd.”

Exo Terra’s T5 UVB bulbs are engineered to provide sufficient and biologically effective UVB output for up to 12 months, offering a reliable and energy-efficient solution for long-term reptile care. Specifically designed to integrate seamlessly with Exo Terra T5 fixtures and compatible with other standard T5 fluorescent light holders, these bulbs offer versatility and practicality for any terrarium setup. Their reliable performance and exceptional quality make them an essential component for creating optimal habitats that meet the diverse needs of reptiles.

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

For optimal results and prolonged lifespan of the bulb, we recommend using it in conjunction with the Exo Terra® T5 Terrarium Top High-Performance Reptile UVB Fixture.The longer sizes can be placed across multiple terrariums.

Long-lasting UVB output (12+ months).

Keepers can use the UV Index reference values to ensure that animals are exposed to an appropriate level of UV when basking. The intensity of the emissions varies depending on the distance from the basking area. 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.

The UV radiation output of all UV-emitting bulbs gradually decreases over time. To ensure your animals consistently receive sufficient UV exposure, we recommend replacing the Exo Terra® Reptile UVB T5 tube — or any other UV bulb — at least every 12 months.

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.
