The SureFire Maximus rechargeable variable-output LED headlamp delivers 1,000 lumens of light, enough to illuminate your entire campsite. If that's too much light, you can dial it down to 1 lumen or any level in between for closer work, preserving your dark-adapted vision or extending the runtime. Features a large knurled dial permits output control with one hand even if it's gloved or numbed by cold; light rotates up and down 90 degrees; battery charge level, no-chafe headband w/moisture wicking Breath-O-Prene forehead pad and an SOS beacon provides an extra margin of safety. Includes battery, wall and car charger.
