The Exo Terra Reptile UVB300 is specifically tailored for reptiles that thrive in environments with intense, direct sunlight, such as deserts or open savannahs.
With its 14% UVB output, this bulb delivers the highest UV intensity among the T5 series, meeting the needs of reptiles requiring high levels of UVB exposure. Supporting Ferguson Zones 3-4 and the Euphotic and Heliophotic Zones, it provides the UVB necessary for open and mid-day sun baskers. The UVB300 is critical for maximizing vitamin D3 synthesis, which is essential for robust bone growth, healthy shells, and preventing metabolic bone disease (MBD). This bulb is ideal for large enclosures or terrariums with minimal shading, replicating the intense sunlight found in arid and semi-arid regions. Its high UV output ensures reptiles receive adequate exposure even at greater distances from the bulb. To avoid overexposure, the positioning and distance from the basking area should be carefully considered. When used alongside basking lights and proper thermal setups, the UVB300 creates a complete and enriching environment that supports the health and natural behaviors of reptiles in high-UV habitats.
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 UVB300 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.
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.
