Reptile Systems Eco T5 Unit Zone 1 – 8W 312mm Vivarium UV Lighting Kit

The RS Eco T5 Unit Zone 1 is a compact, single-lamp T5 lighting unit designed for reptile keepers who need reliable, full-spectrum UV output in a straightforward package. At 8W and 312mm, it suits smaller vivariums and is matched to Ferguson Zone 1 species — those that receive lower UV exposure in the wild and typically avoid direct, prolonged basking. Everything needed to get the unit running is included in the box.

Built-in Reflector

The unit features a 103° removable reflector with an uncoated, highly reflective surface. This wide spread angle maximises usable light across the vivarium floor, giving Zone 1 inhabitants access to appropriate UV gradients without intense hotspots.

Lamp and Ballast

The RS Eco T5 Unit combines a HOT5 lamp with an electronic, flicker-free ballast in a single integrated assembly. The electronic ballast eliminates the flicker associated with older magnetic gear, which is important for reptile welfare — many species can detect flicker that is invisible to the human eye.

Full-Spectrum UV Output

The lamp is designed to replicate the spectral profile of natural sunlight as closely as possible, delivering balanced UVA and UVB alongside accurate natural colour rendering. UVB exposure enables reptiles to synthesise vitamin D3 through a self-regulating photochemical process — essential for calcium absorption and the prevention of metabolic bone disease.

Ferguson Zone 1 — Suitable Species

Zone 1 covers crepuscular and shaded-environment species that experience low ambient UV in their natural habitat. Examples include:

• Crested gecko
• Leopard gecko
• Corn snake
• Reticulated python
• Red-eyed tree frog

What's in the Box

The unit ships with a fixing kit, link cable, straight connectors, and a mains power lead — everything required for straightforward installation with no additional hardware needed.

For keepers setting up a Zone 1 vivarium or upgrading from an older fluorescent unit, the RS Eco T5 Unit delivers the core UV provision your animals need in a compact, easy-to-install format.
