Reptile Systems D3 UV Basking Lamp Nano 70w - Mercury Vapour Reptile Lamp

The RS D3 UV Basking Lamp Nano 70w is a self-contained mercury vapour lamp designed for reptile vivariums where space is at a premium but UV and heat output cannot be compromised. It delivers UVB, UVA, visible light, and infrared heat from a single bulb — no external ballast required — making it a straightforward, clutter-free solution for keepers who want reliable all-in-one basking provision.

What It Delivers

• Simultaneous UVB, UVA, visible light, and infrared (heat) output from one lamp
• Aids Vitamin D3 synthesis, supporting healthy calcium metabolism
• Helps prevent metabolic bone disease in reptiles
• Stimulates natural reproductive behaviour
• Important for overall reptile development and long-term health

Beam and Coverage

A 35-degree beam angle produces a focused but generous basking zone. This concentrated spread is well suited to smaller vivarium footprints where a tighter basking spot is preferable, ensuring the animal can thermo-regulate effectively without the rest of the enclosure being overheated.

UV Output and Quality Assurance

UV output is rated at a UVI of 2.7, measured at 30cm without a reflector after six months of use — a post-run figure that reflects real-world performance rather than out-of-the-box peaks. Every lamp undergoes a triple quality check to verify UVI output meets specification before leaving the factory, and the UVI rating is displayed on the packaging so keepers can make an informed choice.

Lamp Life and Installation

• Rated average lifespan of 3,000 hours
• No external ballast required — fits a standard lamp fitting
• Self-ballasted design keeps installation simple and wiring tidy

For reptile keepers who need a compact, no-fuss mercury vapour lamp with independently verified UV output, the RS D3 UV Basking Lamp Nano 70w gives you measurable performance and the confidence that comes from transparent quality standards.
