## Overview

The Arcadia D3 Reptile 7% T5 ShadeDweller UVB bulb is a specialized 8W fluorescent tube designed to deliver optimal UVB and UVA lighting for shade-dwelling reptiles. Measuring 300mm, it supports natural vitamin D3 synthesis critical for calcium metabolism and bone health. Engineered for crepuscular species, it provides broad UV coverage in compact enclosures and integrates seamlessly with Arcadia’s ProT5 and MiniT5 systems, making it a must-have for professional reptile keepers seeking precise, species-specific lighting solutions.

## Description

The Arcadia D3 Reptile T5 7% UVB ShadeDweller is a specialist UVB reptile lamp designed to provide a suitable source of UV-rich lighting for shade-dwelling and crepuscular reptiles. Producing 7% UVB and 17% UVA, this compact T5 fluorescent tube helps recreate important aspects of natural sunlight within a carefully designed vivarium environment. UVB exposure plays an important role in reptile husbandry, supporting vitamin D3 synthesis and helping reptiles utilise dietary calcium as part of a balanced diet and appropriate care routine. The ShadeDweller has been developed with species that naturally spend much of their time in shaded environments in mind, making it suitable for reptiles including leopard geckos, crested geckos, corn snakes, king snakes and milk snakes when correctly positioned. The 8W T5 tube measures approximately 300mm (12 inches), making it ideal for smaller vivariums and enclosures where a compact UVB solution is required. It provides a broad spread of UV-rich light when used with a suitable reflector and compatible lighting system. Designed for use with Arcadia ProT5 and MiniT5 ShadeDweller systems, as well as suitable T5 8W controllers and the Arcadia 8W UV MiniKit. Always follow species-specific UVB requirements and manufacturer guidance when installing and positioning reptile lighting.

## Questions & Answers

**Q: My bulb has only lasted 4 weeks, is this normal?**
A: No, definitely not. Mine is still working after nearly a year although I swapped it out after 7 months due to the UVB getting weaker over time. Check if it's set up correctly, if it's not connected properly it might blow the bulb. I had it turned too far to one side at the beginning and it started flickering.

**Q: Is this suitable for bearded dragons**
A: No it is not, it is for nocturnal animals.

**Q: Is this the 12’ bulb**
A: Yes :)

**Q: What mm length is this?**
A: 290mm
