Reptile Systems Eco T5 Unit Zone 4 – 24W 570mm Vivarium Lighting Kit

The RS Eco T5 Unit Zone 4 is a complete single-lamp T5 lighting kit designed for reptiles with high UV requirements. At 24W and 570mm, it combines a HOT5 UVB lamp, an electronic flicker-free ballast, and a 103° removable reflector in one ready-to-fit bundle — everything a keeper needs to deliver consistent, full-spectrum lighting to their vivarium from day one.

Reflector & Light Output

The built-in 103° reflector is removable and features an uncoated, highly reflective surface that distributes light broadly and powerfully across the vivarium floor. This wide spread is particularly important for Zone 4 species, which require strong, consistent UV exposure across a significant basking area rather than a narrow beam.

Full-Spectrum UVA & UVB Performance

The included HOT5 lamp is engineered to replicate the natural solar spectrum as closely as possible, delivering balanced UVA and UVB output alongside accurate, natural colour rendering. UVB 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 4 Explained

The Ferguson Zone system categorises reptile species by their natural UV exposure and basking behaviour, providing a science-based framework for replicating appropriate light levels in captivity. Zone 4 represents species that inhabit open, sun-drenched environments and regularly bask in intense UV radiation — the RS Eco T5 Unit Zone 4 is specified to meet these demands.

Examples of Ferguson Zone 4 Species

• Saharan uromastyx
• Inland bearded dragon
• Central Asian tortoise
• Sunwatcher toad-headed agama

What's Included

The unit ships as a complete kit including a fixing kit, link cable, straight connectors, and a mains power lead. The lightweight construction keeps installation straightforward, and all the components needed for a clean, functional setup are in the box.

For keepers housing high-UV desert or arid-environment species, this unit removes the guesswork — the lamp grade, reflector geometry, and wattage are matched specifically to Zone 4 requirements, giving you confidence that your animals are receiving appropriate light from a single, purpose-built solution.
