3% UVB
Replicates solar UVA & UVB
High quality
Long lasting output
Exo Terra’s T5 fluorescent Reptile UVB lighting range is designed to provide reptiles, amphibians, and invertebrates with optimal UV exposure, ensuring their health and well-being in captivity.
Crafted with precision in Germany, Exo Terra’s T5 Very High Output (VHO) bulbs offer long-lasting UVB and UVA emissions that mimic natural sunlight. Exo Terra T5 bulbs come in three strengths - Reptile UVB 100, 200, and 300 - each tailored to specific habitat zones to provide varied UV intensities to meet the specific needs of your animals.
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.
Developed using German precision technology, the innovative Sunergy™ phosphor blend, helps 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 behaviour.
Recommended for use with the Exo Terra T5 Terrarium Top High-Performance Fixture (sold separately).
