The ability to bring high-end technology to a compact, fully-redesigned, extremely powerful light source is finally here. The REDLINE is our brightest flashlight to date, 220 lumens of pure white light to be exact. In automobiles, redlining is reaching the peak of its performance, whereas we, with NEBO REDLINE are harnessing the maximum power of this flashlight with 220 lumens of blinding bright light. (NOTE: Anything above 50 lumens within a 10 yard distance may cause temporary blindness when viewed directly.) The REDLINE has 5 lighting modes, 100-Percent white light (220 lumens), 50-Percent white light (110 lumens), 10-Percent white light (22 lumens), S.O.S. mode (220 lumens), or emergency strobe mode (220 lumens). This flashlight has a 4x adjustable beam that works with any light setting to change the REDLINE from a flood light to illuminate everything within a 20 yard distance, or to a spot light to focus up to 150 yards. The bezel of the REDLINE controls the adjustable beam. The red ring of the NEBO REDLINE enhances all of the features of this flashlight.
