Exo Terra Reptile UVB 200 Bulb, 18 W, 24in

Emits the precise UVB range needed for optimal Vitamin D3 photosynthesis, perfect for species with very high UV requirements. Simulates intense, direct sunlight found in desert environments where reptiles naturally receive strong, unfiltered UVB exposure. Promotes increased Vitamin D3 production to support calcium absorption and help prevent metabolic bone disease. Strong UVB output makes this bulb ideal for tall terrariums or enclosures with dense screen tops that typically block UV radiation. UV output decreases over time; yearly replacement ensures consistent, healthy lighting. Pet‑care bulb for reptiles, amphibians, and invertebrates only.
