Known as one of the world’s brightest focusable headlights, The ExtremeBeam OSR-800 weighs in at only 3.5 ounces yet puts out a strikingly bright beam which, when focused, can reach an amazing distance of over 165 meters (550 feet). The OSR-800 can be used on high for spotting at a distance, or the light can be switched into “hike mode” for a 24 hour run time on 3 AAA batteries. The beam can be spread wide in order to read a map or see the trail ahead, or be instantly focused to see far away objects and the bottom of deep canyons. The OSR-800’s third mode is a rapid flash signaling mode. In any of the on positions, a hiker can hold the button down for 4 seconds to enter an S.O.S. flashing sequence. which when shined upwards, is readily identifiable by both commercial and private aircraft pilots. The adjustable head-tilt and superior performance of this 160 lumen light makes the ExtremeBeam OSR-800 the perfect light for hikers, campers, spelunkers, hunters and many others who need a reliable high-performance light with great efficiency. The OSR-800 is outperforming nearly every headlight by any other competitor under 140.00 for a fraction of the price.
