Exo Terra Reptile UVB 100 Tube 14W 15in | T8 UVB Lamp PT2384

The ET Reptile UVB 100 Tube 14W 15in (PT2384) is a T8 fluorescent UVB lamp designed for tropical and rainforest reptile setups. It replicates the moderate, filtered UV conditions found in shaded jungle environments — the kind of light that reaches reptiles living beneath a forest canopy, where humidity, cloud cover, and vegetation naturally diffuse direct sunlight. If you keep species from these habitats, this tube is calibrated to match what they'd actually experience in the wild.

UVB Output and Vitamin D3 Synthesis

The UVB 100 is formulated to deliver an optimal Vitamin D3 yield index, supporting the photosynthesis of D3 within the reptile's skin. This directly aids calcium absorption and plays a critical role in preventing metabolic bone disease — one of the most common and avoidable husbandry failures in captive reptiles. The output level suits species that receive moderate rather than intense UV exposure in nature.

Habitat Match: Tropical and Rainforest Species

This tube is appropriate for reptiles native to environments where sunlight is naturally filtered — think rainforests, cloud forests, and similarly humid tropical zones. These animals are accustomed to indirect or partially shaded UV, not the intense exposure of an open desert. Matching the UV index to the animal's natural environment is a key part of evidence-based husbandry.

Packaging and Reference Data

• Full spectral graph included on packaging for light output verification
• UV spectral graph detailing UVB and UVA emission profiles
• Reptile Bulb Rating System reference to help cross-compare with other lamps
• Distance-related data including UVB output at varying distances and photosynthesis information
• Ferguson Zone guidance to help position the lamp correctly for your species
• UVB chart for practical placement and enclosure setup reference

Fitting and Placement

At 15 inches, this T8 tube fits standard fluorescent T8 controllers and canopies suited to smaller or mid-sized terrariums. The compact length also makes it practical for use across multiple smaller enclosures when a full-length tube would be excessive.

For keepers who take lighting seriously, the ET Reptile UVB 100 Tube 14W 15in gives you the data you need on the packaging and the correct UV profile in the tube — a straightforward, well-specified choice for tropical reptile lighting.
