Zoo Med Repti Tuff Splashproof Halogen Lamp, 50 Watt, 75 Watt, 90 Watt Wide beam range for optimal light Excellent colour rendition. 2.5 / 3 times the life of tungsten filament lamps. 25-degree beam angle. Dimmable. Emits no harmful UV. We recommend using our halogen bulb above a screened enclosure to protect your animal from contact with the bulb preventing burns.
