Reptile Systems T5 UVB Lamp Ferguson Zone 1 - 2.4%

The Reptile Systems Zone 1 T5 UVB lamp is designed for reptiles and amphibians that naturally inhabit low-UV environments — Ferguson Zone 1 species that receive only filtered or incidental sunlight in the wild. Available in four sizes to suit vivarium setups of different scale, this range delivers precisely calibrated UVB and UVA output to support natural physiology without overexposure.

UV Output

Each lamp in this range emits 2.4% UVB, supporting the synthesis of vitamin D3 for healthy calcium metabolism. UVA output is set at 30%, contributing to natural behaviour, appetite, and colour perception. The extra high output specification means the lamp performs consistently across its rated lifespan rather than degrading rapidly after installation.

Natural Colour Rendering

Beyond UV, these lamps are engineered to produce accurate, natural colours within the vivarium. This benefits both the keeper — making the enclosure look as it should — and the animal, which relies on good light quality for normal visual processing and activity patterns.

Compatibility and Installation

These lamps require a T5 electronic ballast to operate and will not function with older T8 or fluorescent fittings. For best results, pair with a compatible T5 luminaire or electronic controller. As with all UV lamps, output degrades over time — replacement after one year of normal use is recommended to maintain reliable UV levels.

Choosing the Right Size

This range is available in four sizes, from compact options suited to smaller terrariums through to full-length tubes for larger vivarium builds. Select your preferred size and wattage from the variant options above to match the lamp to your enclosure length.

For keepers housing Zone 1 species — from certain dart frogs and crested geckos to forest-dwelling skinks — the Reptile Systems Zone 1 T5 provides a straightforward, species-appropriate lighting solution backed by precise UV specifications.
