Reptile Systems Compact Lamp Zone 3 13w UVB Bulb for Reptile Vivariums

The RS Compact Lamp Zone 3 13w is a self-ballasted UVB compact lamp designed for reptile keepers housing species that need meaningful UV exposure in their vivarium. At 13w, it delivers Zone 3-level UVB output — suited to reptiles that occupy open, sun-exposed environments and require reliable UV to drive vitamin D3 synthesis and support calcium metabolism.

Zone 3 UV Output

This lamp produces a UVI of approximately 2.8 at 30cm, placing it firmly in the range required by desert-dwelling and open-habitat species. That level of UVB exposure supports bone health and helps prevent deficiency-related conditions that are common where lighting is inadequate or ageing.

Features and Specifications

• Zone 3 UVB output: UVI of approximately 2.8 at 30cm, suitable for higher-UV-requirement species
• 13w self-ballasted design: fits standard E27 screw sockets with no external ballast required
• Full-spectrum illumination: strong colour rendering so animals appear natural and vivid under the light
• Compact form factor: well-suited to smaller and medium-sized vivariums where space is limited but UV output cannot be compromised

Lamp Replacement and Maintenance

UVB output degrades over time even when the lamp still produces visible light. Replace the RS Compact Lamp Zone 3 13w every 6–9 months to ensure your animal continues to receive effective UVB levels throughout the lamp's service life.

Suitable Species

This lamp is a practical choice for bearded dragons, day geckos, and other Zone 3 reptiles that require higher-energy UVB in their enclosure. If you keep species from open, sun-exposed habitats, this compact lamp delivers the output their physiology demands.

Straightforward to fit and effective where it matters, the RS Compact Lamp Zone 3 13w gives keepers a dependable way to meet the lighting and UVB needs of their animals without overcomplicating the setup.
