Bright lights, burly cases, fail-safe on/off switches, virtual indestructibility: there are good reasons to rave about Mag Instrument flashlights. Powered by 3 D-cell batteries, the bright, powerful light adjusts from spot to flood simply by rotating the head. The light is housed in a case made of high-strength aluminum alloy that has been anodized inside and out. This, along with high-quality O-rings at both openings, give you water- and shock-resistance in a lightweight package. Maglite"s switches are rubber-coated, weather-protected, and self-cleaning-they"re virtually indestructible. In short, this flashlight is almost indestructible-a good quality when it comes to the tools re rely on to help you find your way in the dark. Limited lifetime warranty. Requires 3 D-cell batteries (not included). Includes spare bulb (stored in end-cap). If you want the same design in a smaller package or if you want more run-time than 3 D-cells will give you, see Mag Instrument products #S2D016 and #S4D016.--Josh DettweilerWhat"s in the Box Flashlight, spare bulb
