Reptile Systems T8 UVB Lamp Ferguson Zone 2 - 6%

The Reptile Systems Zone 2 T8 is a full-spectrum UVB fluorescent tube designed for reptiles and amphibians that occupy Ferguson Zone 2 — species that bask intermittently and benefit from moderate UVB exposure. Available in a range of sizes to suit vivarium setups of different scales, this tube delivers a UVI of 2.0, making it a reliable choice for supporting natural behaviour and long-term health in a broad range of commonly kept species.

What Ferguson Zone 2 Means

Ferguson zones are an evidence-based framework for matching UVB output to a species' natural sun exposure behaviour. Zone 2 covers animals that spend some time basking in open sunlight but also seek shade regularly. Providing the correct UVI for your species is one of the most important factors in successful long-term keeping.

UVB and D3 Synthesis

This tube produces UVB at a level that supports vitamin D3 synthesis through the skin — the same process that occurs in the wild. Adequate D3 is essential for calcium metabolism, and getting it right through appropriate lighting is far preferable to relying solely on dietary supplementation.

Beyond UVB — Full Spectrum Output

• Full spectrum output that renders natural colours and iridescence accurately
• Supports improved feeding response and breeding behaviour
• Suitable for both reptiles and amphibians within Zone 2
• Always provide shaded areas within the enclosure so animals can self-regulate

Suitable Species

Zone 2 covers a wide range of popular vivarium inhabitants. Keepers of the following species should consider this tube:

• Royal Python
• Boa Constrictor
• Brazilian Rainbow Boa
• Californian King Snake
• Asian Water Dragon
• Red Foot Tortoise
• Jackson's Chameleon
• Gargoyle Gecko
• Electric Blue Day Gecko
• Common Musk Turtle
• Cane Toad

Replacement Schedule

UVB output degrades before the visible light does — a tube that still looks bright may no longer be producing meaningful UVB. Reptile Systems recommend replacing T8 tubes every six months to ensure your animals are receiving consistent, effective UVB throughout the year.

Select the tube length that fits your existing T8 fitting and suits the scale of your enclosure — the range covers setups from smaller vivaria through to larger, more ambitious builds. Getting the size right ensures even coverage and reliable UVB delivery across the basking zone.
