The RS Compact Lamp Pro - D3 12% UVB - 23w is a high-output compact fluorescent UV lamp designed for reptile keepers who need reliable UVB provision and D3 synthesis in a single screw-fit bulb. Built for use as a UV basking lamp, it suits species with moderate to high UV requirements and fits directly into any standard E27 fitting — no ballast or specialist controller required.

UV Output

• 12% UVB for effective D3 synthesis
• 30% UVA supporting natural behaviour and appetite
• Average UVI of 1.7 measured at 30cm without a reflector, based on six months of long-term testing

Spectrum and Light Quality

This lamp produces a full-spectrum output with excellent colour rendition, meaning your animals are viewed under natural-looking light and the vivarium interior is accurately lit. Full-spectrum output also supports the photoperiod needs of the animals kept beneath it.

Fitting and Compatibility

The RS Compact Lamp Pro uses a standard E27 Edison screw fitting, making it straightforward to install in the vast majority of compact lamp holders and purpose-built reptile luminaires. It runs at 23W and is not dimmable — it should be used on a standard on/off timer rather than a dimming thermostat.

For keepers who want a compact UV basking solution without complex wiring or additional hardware, the RS Compact Lamp Pro - D3 12% UVB - 23w delivers measurable UV output in a format that works across a wide range of vivarium setups.
