Reptile Systems Zone 2 T8 UVB Lamp (

The Reptile Systems Zone 2 T8 UVB lamp is a full-spectrum fluorescent tube designed for reptiles and amphibians that receive partial, intermittent sun exposure in the wild — basking opportunistically rather than continuously. Available in a range of sizes to suit vivarium setups of different scales, this tube delivers UVB output calibrated to Ferguson Zone 2, supporting species that need moderate UVB provision rather than intense desert-level exposure.

Ferguson Zone 2 Explained

Ferguson Zone 2 covers species that spend part of their time in open light but also retreat to shade. In practice, this means a UVI output of around 2.0 — enough to drive meaningful vitamin D3 synthesis without overwhelming animals adapted to filtered or broken light. Positioning the tube approximately 12 inches above the primary basking zone is recommended for T8 format lamps.

What This Lamp Does for Your Animals

• Supports vitamin D3 synthesis through UVB exposure at Zone 2 UVI levels
• Full-spectrum output that renders natural colours and iridescence accurately
• Encourages more natural feeding and breeding behaviour
• Suitable for both reptiles and amphibians within the Zone 2 classification
• Always provide shaded retreats so animals can self-regulate their UVB exposure

Species Suited to Zone 2 UVB

This tube is appropriate for a broad range of popular and specialist species. Examples of animals that fall within Ferguson Zone 2 include Royal Pythons, Boa Constrictors, Brazilian Rainbow Boas, Californian King Snakes, Asian Water Dragons, Jacksons Chameleons, Red Foot Tortoises, Gargoyle Geckos, Electric Blue Day Geckos, Common Musk Turtles, and Cane Toads.

Tube Replacement

As with all fluorescent UVB tubes, UVB output degrades over time before the lamp visibly dims. Replacing the tube every six months ensures your animals continue to receive accurate, effective UVB levels regardless of how much visible light the tube still appears to produce.

Choosing the correct size for your enclosure is straightforward — the range covers several lengths to match standard vivarium and terrarium dimensions. Select the appropriate variant from the options on this page to ensure the tube fits your setup and your lighting unit.
