The new Ion Pen Light, from Koehler Bright Star, is rugged, compact and carries an industry-leading 135 lumens that will cast a light 100 feet and is engineered to provide a high lumen output though the entire three-hour runtime. The Ion makes it easier than ever to carry the brightness of a big flashlight in a form that fits in a shirt pocket.
The rear button switch can be operated in a momentary mode or continuous light. The Ion Pen Light’s construction is anodized aircraft aluminum and it comes with a pocket clip attachment. Just 5- 1/8 inches long and 5/-inches wide, it is drop-rated at 2 meters, water-proof to one meter and powered by 2-AAA batteries (not included).
