The HP190LS combines a brilliant white light with a bright red aiming laser. It uses a highly efficient, recoil-proof L.E.D. to generate 190 lumens of blinding white light with a 5-milliwatt, 650-nanometer laser sight, located below the light. Light of this magnitude is enough to dominate an aggressor's night-adapted vision, so it's ideal for military, law enforcement and self-defense use. The reflector lens focuses the beam for long-distance lighting while also producing enough light to support the user's peripheral vision. The HP190LS batteries will produce 3 hours of continuous illumination.
