The Reptile Systems Eco T5 Unit Zone 1 is a complete, ready-to-run T5 lighting kit designed for crepuscular and shade-dwelling species that require lower UV output. Available in a range of sizes to suit enclosures of different scale, each unit combines a Reptile Systems HO T5 lamp with a reliable, electronic, flicker-free ballast in a single lightweight fitting — everything you need to provide 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-spread reflector maximises light and UV distribution across the enclosure floor, delivering some of the strongest results achievable from a unit of this type.
Full-Spectrum UV Output
Reptile Systems lamps are engineered to replicate the solar spectrum as closely as possible, producing balanced UVA and UVB output 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 — What That Means
Zone 1 of the Ferguson Zone system covers species that naturally occupy shaded or crepuscular environments and have a low requirement for UV exposure. Choosing the correct zone ensures your animal receives UV levels appropriate to its natural behaviour and habitat rather than a one-size-fits-all output.
Animals Suited to Zone 1
- Crested gecko
- Leopard gecko
- Corn snake
- Reticulated python
- Red-eyed tree frog
What's Included
Every unit ships with a fixing kit, link cable, straight connectors, and a mains power lead — so installation is straightforward without needing additional components. The fittings are compatible with standard vivarium and terrarium setups.
Select the size that best matches your enclosure from the options above. Getting the right coverage for your vivarium's footprint is as important as choosing the correct Ferguson Zone, and the range of available sizes makes it straightforward to spec the unit correctly for your setup.
