A Maglite 3D Light S3D is designed tough enough to last a lifetime. Maglite's cam driven beam changes from spot to flood with a turn of the head for the perfectly focused beam. A set of O rings at each opening ensure a Maglite is resistant to water and steadfast in its ability to withstand shock. The light has an anodized finish inside and offers optimum corrosion resistance and prevents battery damage, and a knurled handle for a better grip. Every reflector is computer designed to work with a specific lamp and power supply to achieve maximum brilliance and efficiency. A quality White Star krypton lamp delivers exceptional performance.
