The TUBE has a 100° beam so your peripheral, as well as direct line of sight, is illuminated. Comes with a high, low, and "infinitely variable brightness" mode, the TUBE features a transparent polycarbonate casing, known for it's high-strength and outstanding impact resistance. This is a light you'll want to keep on your keys, bedside table, or in your glove box.
