Sundew Mercury Vapor UVB Reptile Bulb, PAR38 120V E26 – Clear Glass High-UVB Output (100, Watts)

The Sundew PAR38 Mercury Vapor UVB Reptile Bulb (Clear Glass Series) provides strong UVB, UVA, and basking heat for reptiles that naturally depend on higher exposure levels. The clear, uncoated glass maximizes UV penetration, supporting vitamin D3 synthesis and efficient calcium absorption. UVA encourages healthy appetite and daily activity, while the strong heat output creates a dedicated basking spot reptiles can use throughout the day. Designed for 120V E26 ceramic fixtures, this self-ballasted bulb requires no external ballast, making setup simple and dependable. The large PAR38 reflector directs UVB and heat effectively, delivering deeper reach ideal for bearded dragons, uromastyx, iguanas, monitors, tortoises, and other species that prefer intense basking conditions. Built for durability, the bulb offers up to 6,000 hours of working life. Install vertically, avoid dimmers and thermostat-style controls, and ensure proper ventilation for best performance. Available in 80W, 100W, 125W, and 160W, allowing reptile keepers to match output to enclosure size and species needs. For reptile UVB lighting only. Not for household or general illumination.
