Exo Terra Reptile UVB 200 Tube 14W 15in PT2350 | High-Output Desert UVB T8

The ET Reptile UVB 200 Tube 14W 15in (PT2350) is a high-output T8 fluorescent tube built specifically for desert-dwelling reptiles with demanding UV requirements. Diurnal species from arid environments — think uromastyx, agamas, and bearded dragons — are exposed to intense, unfiltered sunlight in the wild. This tube is designed to replicate those conditions inside the vivarium, delivering a significantly elevated UVB output that supports robust vitamin D3 synthesis and long-term calcium metabolism.

High UVB Output for Desert Species

This tube produces a UVB spectrum calibrated for reptiles that require very high ultraviolet exposure. The high vitamin D3 yield index supports effective D3 photosynthesis, which in turn aids calcium absorption and helps prevent metabolic bone disease — one of the most common keeper-preventable conditions in captive reptiles. It is not intended for species with moderate or low UV requirements; it is purpose-built for those that need the most.

Extended Penetration for Taller Enclosures

The UVB output from this tube is strong enough to penetrate further than standard lamps, making it a practical choice for taller terrariums or enclosures fitted with denser mesh screens. Wire and aluminium screens can significantly reduce UV transmission, so the increased output helps ensure meaningful UVB still reaches your animals at basking distance.

Longer Format, Flexible Placement

At 15 inches, this tube can be positioned to cover multiple smaller terrariums simultaneously, which makes it a practical option for keepers running several enclosures side by side. The T8 format is widely compatible with standard fluorescent hoods and controllers.

Detailed Packaging Information

• Full spectral graph and UV spectral graph included on packaging
• Reptile bulb rating system clearly displayed
• Distance-related UVB output and photosynthesis data provided
• Ferguson Zone guidance and a reptile UVB chart included for accurate placement

For keepers who take UV provision seriously, the ET Reptile UVB 200 Tube 14W 15in gives you the output data and species-specific guidance needed to make informed decisions about lamp height, screen type, and replacement schedules.
