Bring the power of the natural sun right into your terrarium with the Reptile One Tube T5 Reptile 12% UVB. Engineered specifically for desert-dwelling, sun-seeking species, this high-output T5 fluorescent tube mimics the intense solar radiation found in their native habitats. It provides a finely tuned balance of UVA and UVB wavelengths to encourage natural behaviors, support a robust immune system, and ensure your exotic pet thrives in captivity.
High 12% UVB Output: Specially designed for sun-seeking reptiles with high UVB requirements to support strong bone development.
Optimal D3 Synthesis: Assists in the vital natural production of Vitamin D3, enabling efficient calcium metabolism to prevent Metabolic Bone Disease (MBD).
Full Spectrum Lighting: Accurately reproduces the UVA and UVB spectra found in natural sunlight to stimulate healthy appetite, vibrant coloration, and natural activity levels.
Designed for Larger Enclosures: Optimized for deeper, larger terrariums with a high UV Index (UVI) reach when positioned at a recommended distance of 300 mm to 350 mm from the basking zone.
Perfect Compatibility: Engineered to fit seamlessly into Reptile One ReptiGlo T5 Reflectors (sold separately).

Pro Tip
Even though T5 tubes stay bright for a long time, their invisible, life-saving UVB output degrades significantly over time. To ensure your reptile always gets the essential UV rays they need to process calcium, mark your calendar to replace the tube every 9 to 12 monthsâeven if the bulb still looks perfectly lit to the human eye!
