Reptile Systems Compact Lamp Pro D3 6% UVB 23W Reptile Vivarium Bulb

The RS Compact Lamp Pro - D3 6% UVB - 23w is a high-output compact fluorescent lamp designed for reptile keepers who need reliable UVB provision and full-spectrum lighting in a single screw-fit bulb. Built for use as a UV basking lamp, it suits species that require meaningful D3 synthesis without the complexity of a separate ballast or controller.

UVB, UVA & UVI Output

• 6% UVB — suitable for driving Vitamin D3 synthesis in reptiles with moderate to high UV requirements
• 30% UVA — supports natural behaviours and visual acuity in UV-sensitive species
• 1.3% average UVI measured at 30cm without a reflector, recorded over a six-month long-term test period

Wattage & Spectrum

Running at 23 watts, this lamp delivers full-spectrum output with excellent colour rendition, rendering your vivarium's inhabitants and décor accurately under natural-looking light. The broad spectrum supports both keeper observation and the animal's own photoperiod response.

Installation & Compatibility

The RS Compact Lamp Pro - D3 6% UVB - 23w fits a standard E27 screw fitting and requires no external ballast, making it straightforward to retrofit into most vivarium canopies and lamp holders. Note that this lamp is not dimmable and should not be used with dimmer switches or dimming thermostats.

How to Use

Position this lamp as a UV basking source, placing it within your vivarium so the animal's basking zone falls within the effective UVI range. Using a reflector will increase UVI delivery beyond the 1.3% baseline figure quoted above. Replace on a regular schedule in line with UVB lamp guidance, as UV output degrades before visible light output diminishes.

For keepers who want a compact, ballast-free UVB solution with verified output data, the RS Compact Lamp Pro - D3 6% UVB - 23w offers a straightforward fit into any E27 setup without compromise on spectral quality.
