The L4 Digital Lumamax, made by Surefire, is a flashlight that is waterproof up to a depth of 33 feet. This durable flashlight features the Luxeon V LED light, an easy-to-use clip, and a strong hard-anodized Type III finish. The L4 is an ideal on-the-go device. At just 3.4 ounces, it will not weigh you down. It measures just over 5 inches long, and has a diameter of 1 inch. Its slim profile means it will slide easily into a pocket or backpack.Unlike the usual yellow lights, the L4 Digital Lumamax emits white light from LED lightbulbs. It shines at a bright, focused 170 lumens. Detailed texturing on the reflector trains the streamlight beam for a smooth, bright shine. The 170-lumen LED is so bright that the L4 can also be carried as a safety measure. For the momentary-on setting, which provides a quick burst of illumination, give the tailcap button a quick tap. If you need the device to stay on, push the switch longer for constant-on mode.The aluminum body boasts aerospace technology. It is Mil-Spec Type III hard-anodized, so it is hardy enough for nearly any circumstance. Plus, the window is made of tempered Pyrex. Since the Surefire has an LED instead of a traditional bulb, there is no worry about the filament breaking during falls or intense activity. This flashlight is cold resistant, and great for travel and camping. It can withstand high falls due to its impressive durability. Because it is sealed with an O-ring, it is impervious to inclement weather, such as cold and rain. It's portable enough that it can be an everyday tool but hardy enough to be used as tactical gear.Powered by two 123A lithium batteries, the L4 gives off about five times as much light as a flashlight that runs on two D batteries. It has an hour of full-power runtime from one lithium battery set. After an hour, the light will fade slightly, but it won't completely die. In fact, it will provide some illumination for up to an hour and a half longer.Thanks to handy accessories, this flashlight is easy to access when it is needed most. The clip can be used to secure the Surefire to your pocket, your belt loop, or anything else you'd prefer. Adding to the accessories is a lanyard that is included for another carrying option. It can also be transported safely thanks to the lockout feature. When the lockout feature is on, the Surefire is protected against accidental activation, so it won't turn on in a bag.
