Reptile Systems Compact Lamp Zone 2 13w UVB Bulb for Reptiles

The RS Compact Lamp Zone 2 13w is a compact UVB lamp built for reptiles and amphibians that need moderate ultraviolet exposure — specifically those classified within Ferguson Zone 2. That covers species adapted to partially shaded or dappled-light environments: think arboreal geckos, tree snakes, and similar moderate-UV dwellers. If you're housing species that sit in the shade or at the edge of direct sunlight in the wild, this is the lamp designed around their actual needs.

Ferguson Zone 2 UVB Output

This lamp is calibrated to deliver a UVI of around 2.0 at typical basking distances, replicating the UV levels found in shaded or edge-of-sun habitats. That moderate output supports vitamin D3 synthesis without exposing Zone 2 species to UV intensities that exceed what they'd naturally encounter. Correct UVB exposure underpins healthy calcium metabolism and helps prevent conditions linked to deficiency.

Full-Spectrum Performance

Beyond UVB, the lamp provides UVA output alongside a full-spectrum light profile. UVA plays a direct role in natural behaviour, appetite, and how reptiles perceive their environment — it is not a secondary consideration. Full-spectrum output also supports accurate colour rendition inside the vivarium, which matters both for the animal's wellbeing and for observing your animals clearly.

Straightforward Fitting

The RS Compact Lamp Zone 2 13w uses a standard E27 screw base, so it works directly in any compatible dome or lamp holder without the need for separate ballasts or controllers. There is no setup complexity — fit it, switch it on, and it is ready to go. The compact form factor suits smaller vivariums and terrariums where space around the fitting is limited.

For keepers housing Zone 2 species and wanting a reliable, correctly specified UVB source without overcomplicating the setup, the RS Compact Lamp Zone 2 13w covers the biological fundamentals in a practical, easy-to-use package.
