Reptile Systems Eco T5 Unit Zone 4

The Reptile Systems Eco T5 Unit Zone 4 is a complete, ready-to-run T5 fluorescent lighting kit designed for reptiles with high UV requirements. Available in a range of sizes to suit enclosures of different scale, each unit pairs a Reptile Systems HO T5 lamp with a flicker-free electronic ballast in a single, lightweight housing — everything you need to deliver consistent, quality UV lighting straight out of the box.

Built-in Reflector

Each unit features a 103° removable reflector with an uncoated, highly-reflective surface. This wide-angle spread maximises the usable UV footprint across the enclosure floor, giving basking animals full exposure without hot spots or uneven coverage.

Full-Spectrum UV Output

Reptile Systems lamps are engineered to replicate the natural solar spectrum as closely as possible, delivering balanced UVA and UVB output alongside accurate, natural colour rendering. UVB exposure triggers the synthesis of Vitamin D3 through a self-regulating photochemical process, which is essential for calcium absorption and long-term prevention of metabolic bone disease.

Ferguson Zone 4 Rating

This unit is rated for Ferguson Zone 4 — the highest UV category, intended for species that occupy exposed, sun-intense environments with little or no shade. Choosing the correct Ferguson Zone for your species is the most accurate method of matching UV provision to natural basking behaviour and UV index requirements.

Examples of Ferguson Zone 4 Species

• Desert tortoises
• Psammophilus species
• High-altitude and arid-zone agamids
• Species requiring sustained, intense UV exposure in their natural habitat

What's Included

Every unit comes supplied with a fixing kit, link cable, straight connectors, and a mains power lead — so installation is straightforward and no additional accessories are required to get started.

Select the size that best matches your enclosure dimensions from the variants above. Getting the right unit length ensures even light distribution across the basking zone and gives your animals consistent access to the UV levels their biology depends on.
