The MagLite 3 D-Cell Flashlight embodies a balance of refined optics, efficient power, durability and quality, making it well-suited for both professional and consumer use. Each MagLite D-Cell flashlight includes two White Star Krypton gas lamps for enhanced brilliance and range. These lamps create a high-intensity flashlight that can be adjusted from spot to flood with just a half turn of the handle. With its distinctive, shock-resistant design, this flashlight is practical for professional, sporting, home or automotive applications. The durable aluminum-alloy-case flashlight also has a diamond-knurl surface design for grip. This high-intensity flashlight in gray is anodized inside and out, ensuring resistance to corrosion. The MagLite 3 D-Cell flashlight is water-resistant due to its O-ring seal. In addition, the aluminum flashlight has a 3-position function button: on, off and signal. It also features a spare lamp secured safely in the tail cap.
