Extreme conditions demand extreme measures. The rechargeable SureFire Maximus handles them by providing an impressive 1,000 lumens of MaxVision Beam-shaped light that can be dialed down, lumen by lumen, to give you just the right amount. Keep it on lower settings for close-up work, preserving your dark-adapted vision and extending runtime. Turn up the power to illuminate any environment. Its large, knurled dial allows for output control with one hand – even while wearing gloves or in cold conditions. You can also tilt the light assembly up or down to aim the beam precisely where you need it. An SOS beacon offers added safety for those who venture into danger.
