NEBO PROTEC ELITE HP190 uses a highly efficient CREE^® LED to generate 190 lumens of intense white light. Light of this magnitude is enough to dominate an aggressor's night-adapted vision, ideal for military, law enforcement, and self-defense. The reflector lens focuses the beam for long distance lighting while also producing enough light to support the user's peripheral vision. The HP190's batteries will produce 3 hours of continuous illumination. The compact body of the HP190 is constructed of aircraft grade anodized aluminum making it a lightweight, yet powerful light source. The HP190 is also O-ring and gasket sealed to be completely weatherproof. The HP190 features an On-Off switch to provide one-handed operation. This switch allows you to select between 100% white light or defensive strobe. After 10 seconds in the off position, the light will reset to the first setting, which is 100% light.
