The Exo Terra Reptile UVB100 VHO T5 Bulb is designed for shade-dwelling, nocturnal, and crepuscular reptiles that require low to moderate UVB exposure, replicating sunlight filtered through dense vegetation. With a 3% UVB output supporting Ferguson Zone 1 and the Cryptophotic Zone, it promotes vital vitamin D3 synthesis for proper calcium absorption, healthy bone development, and the prevention of metabolic bone disease (MBD). Featuring Exo Terra’s advanced Sunergy™ phosphor blend, developed with German precision technology to closely mimic the sun’s UV spectrum, this T5 lamp delivers highly effective UVA and UVB output with deeper penetration than traditional T8 bulbs, making it suitable for taller terrariums or those with dense screens. Compatible with Exo Terra T5 fixtures and standard T5 holders, it provides reliable, biologically effective UVB for up to 12 months, supports the creation of safe UV gradients for natural self-regulation, and should be replaced annually to ensure consistent performance and reptile health.
