Constructed from shock-resistant polycarbonate, the single-LED L7 flashlight is lightweight and shatter-resistant. It can also withstand extreme temperatures and harsh elements, giving it added versatility. Extremely bright and compact, it puts out a powerful 100 lumens for as long as six hours on three AAA batteries (included). Near-to-far focusing options with the Advanced Focus System are possible because of a patented combination of a reflector and lens to create a light system that provides both a focused beam for long-distance needs and a spill beam for up-close reading.
