Go bold. The G455 flashlight packs big lighting power into a frame just over 8 inches long—a rock-solid solution for when life or work needs illumination. Shining an impressive 1400 lumens on high, the beam on this three-mode dynamo reaches up to 265 meters (869 feet) and runs 33 hours on a single set of batteries.
