Edge to edge, no flashlight in the world today delivers a comparable level of radiant intensity and consistency of brightness. Using patented technology that produces a perfectly uniform – square – pattern of light, our HD™ Torch completely illuminates every inch of its range with a bright, clean light offering superior image definition. Unlike conventional circular flashlight beams, it emits no irregular “blobs” of light and prevents shadows. Thus, it is the perfect tool for locating lost items using the grid/quadrant search method. It can light up an entire wall without moving the beam side to side and is the optimum choice for reading as well. The 165-lumen output lasts for up to 1.5 hours on its two 3-volt lithium batteries (included). Crafted of rugged aircraft-grade machined aluminum with our Find-Me glowing “B” on the rear button.
