Reptile Systems T8 UVB Lamp Ferguson Zone 1 - 2.4%

The Reptile Systems Zone 1 T8 UVB Lamp is designed for species that require low-level UVB exposure — crepuscular animals and those that spend little time in direct sunlight. Available in a range of sizes to suit enclosures of different scales, this full-spectrum T8 tube delivers the gentle UVB output appropriate for Ferguson Zone 1 species without overwhelming animals that actively seek shade.

Ferguson Zone 1 Explained

Ferguson Zones classify reptiles and amphibians by their natural UVB exposure in the wild. Zone 1 covers species that inhabit shaded environments or are most active at dusk and dawn, receiving minimal direct UV in nature. Matching your lighting to the correct zone is essential for accurate husbandry — too much UVB for a shade-dweller can be just as harmful as too little for a basking species.

What This Lamp Does

• Delivers 0.5 UVI — sufficient for vitamin D3 synthesis in low-exposure species
• Full-spectrum output that enhances natural colouration and iridescence
• Supports improved feeding and breeding behaviour
• Suitable for crepuscular animals active at dawn and dusk
• Always provide shaded retreat areas within the enclosure

Compatible Species

This lamp is well suited to a wide range of commonly kept reptiles and amphibians. Species known to fall within Ferguson Zone 1 include:

• Leopard Gecko
• Crested Gecko
• Tokay Gecko
• Cornsnake
• Blood Python
• Green Tree Python
• Reticulated Python
• African Bullfrog
• Red-Eyed Tree Frog
• Oriental Fire-Bellied Toad
• Dyeing Poison Arrow Frog

Installation and Maintenance

As a T8 format tube, this lamp requires a compatible T8 fluorescent fitting. Position the lamp so that the animal's most likely resting or basking spot sits approximately 12 inches below the tube to achieve the intended UVI at animal level. UVB output degrades over time even when the tube still produces visible light — replacement every six months is recommended to maintain effective UVB delivery.

Selecting the correct size for your vivarium or terrarium ensures consistent coverage across the enclosure. Choose from the available options on this page to match your setup — a tube that spans the majority of the enclosure length will give your animals the most natural and usable light gradient.
