REPTILE UVB100 - T5 VERY HIGH OUTPUT UVB100 BULB
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.
Exo Terra’s T5 UVB bulbs are engineered to maintain consistent UVB output for up to 12 months, providing a dependable 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.
