Features include a high power, 10°, 500 lumen white light LED with optional 8Hz strobe plus an 600mW, 8°, infrared LED illuminator. The low power 10 lumen white light or 150mW IR mode is perfect for short range and close quarter applications.
The Mk3 meets MIL-STD-810G environmental testing, mounts to any 1913 Picatinny rail using a Quick Release HT mount, and is precision machined from rugged aerospace aluminum, then MIL-SPEC Type III hardcoat anodized for durability.
The Mk3 is powered by two (2) CR123A lithium batteries housed in a snap-release battery chamber for quick and easy battery changes and is activated by either a remote cable or integrated push button switch—push to illuminate, release to stop or double tap for constant on. A 4-position selector switch allows the user to toggle between modes (high and low power, white light strobe and off).
The Mk3 weighs less than 8 ounces with batteries, measures less than 4 inches long, and is waterproof to over 5 meters.
