Reptile Systems Zone 2 T8 UVB Lamp 450mm 18" 15W | Ferguson Zone 2

The RS Zone 2 T8 450mm (18") 15W is a full-spectrum UVB tube designed for reptiles and amphibians that occupy Ferguson Zone 2 habitats — species that bask intermittently and require moderate UVB exposure to thrive. At 15W and 450mm in length, it fits standard T8 vivarium fittings and is suited to keepers who want reliable, species-appropriate UVB without overexposing animals that don't need intense output.

UVB Output and Vitamin D3 Synthesis

This tube produces a UVI of 2.0, placing it squarely within the Ferguson Zone 2 range. That level of UVB exposure supports the synthesis of vitamin D3, which is essential for calcium metabolism and long-term skeletal health. Position the lamp approximately 12 inches from the primary basking area to achieve the correct UVI at animal level, and always include a shaded retreat so animals can self-regulate their exposure.

Behavioural and Visual Benefits

• Supports natural feeding and breeding behaviour through appropriate UVB stimulation
• Full-spectrum output renders natural colours and iridescence accurately
• Encourages normal activity cycles in species adapted to moderate, dappled light conditions

Species Suited to Ferguson Zone 2

This tube is appropriate for a broad range of commonly kept species. Examples include:

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

Maintenance and Replacement

UVB output from T8 tubes degrades over time, even when the lamp still appears to be working. Replace this tube every six months to ensure your animals are receiving consistent, effective UVB throughout the year. Keep a spare on hand so replacements can be made on schedule without a gap in provision.

For keepers housing Ferguson Zone 2 species in standard T8-fitted vivariums, the RS Zone 2 T8 450mm 15W delivers the correct UVB spectrum and intensity to support health, natural behaviour, and condition over the long term.
