Reptile Systems D3 UV Basking Lamp Nano

The Reptile Systems D3 UV Basking Lamp Nano is a mercury vapour lamp that delivers UVB, UVA, visible light, and infrared heat from a single bulb — no external ballast required. Designed for reptile keepers who want a clean, all-in-one solution for their vivarium, it is available in a range of wattages to suit enclosures of different scales and species requirements.

What It Delivers

Mercury vapour technology means this lamp covers every major component of a reptile's lighting and heating needs in one unit. UVA supports natural behaviour and activity cycles, UVB drives Vitamin D3 synthesis, and infrared output creates a genuine basking zone — all from a single fitting.

Health Benefits for Your Animals

• Aids Vitamin D3 synthesis, which is essential for calcium metabolism
• Helps prevent metabolic bone disease in UV-dependent species
• Supports healthy growth, immune function, and reproductive behaviour
• Provides the kind of broad-spectrum output that matters for long-term reptile health

Output and Build Quality

• 35-degree beam angle produces a focused but wide basking area
• Each lamp passes through Reptile Systems' triple quality check for consistent UVI output
• UVI output is stated on the packaging — measured at 30cm without a reflector after 6 months of use
• Rated average lifespan of 3,000 hours
• Self-ballasted design — no external ballast or separate controller needed

Choosing the Right Wattage

This lamp is available in multiple wattages, from lower outputs suited to compact or nano-scale enclosures up to higher outputs for larger terrariums housing more demanding species. Select your wattage from the options on this page based on your enclosure size and the UV requirements of the species you keep.

With verified UVI figures, a long usable lifespan, and an all-in-one output, the Reptile Systems D3 UV Basking Lamp Nano gives keepers a straightforward, well-documented choice for vivarium lighting and heating.
