Elevate your reptile's habitat with the high performance Arcadia D3 Forest Compact Lamp. This compact bulb provides an increase in visible light output, as well as UV output, even compared to bulbs with similar wattage. UV-B is critical for the synthesis of vitamin D3. The D3 Forest lamp provides 7% UV-B. UV-A produces and enhances eye-catching natural colours, and this reptile lamp provides 30% UV-A. Designed to produce light in wavebands, this unique technology allows for more UV-A and UV-B to flow through the lamp components and into the habitat, and allows more specific parameters to meet the need of each species. 23W.
