From the Exo Terra range, the Reptile UVB300 T5 VHO 39W 34" bulb provides extremely high-intensity UVB output for reptiles that require maximum UV exposure. Combining intense UVB with balanced UVA and visible light, it supports optimal Vitamin D3 synthesis and efficient calcium absorption—ideal for desert-dwelling and sun-loving species. The UVA rays encourage natural behaviours including appetite, activity, and reproduction. Designed for long-lasting performance, this bulb maintains effective UV output for 12+ months and is suitable for all terrarium setups. The UVB300 (14%) strength delivers the highest level of UV exposure for species thriving under strong light. Please note: measurements are manufacturer stated.
