The M600DF Ultra Scout Light is a lightweight, compact weapon light featuring an ultra-high-output LED that delivers 1,200 lumens of blinding white light with 123A batteries and 1,500 lumens of light with the SF18650A rechargeable lithium-ion battery. A proprietary Total Internal Reflection (TIR) lens shapes the recoil-proof LED's light into a beam with plenty of reach but enough surround light to accommodate peripheral vision, making the M600DF ideal for medium to longerrange applications. The rugged M600DF attaches quickly and securely to any MIL-STD-1913 rail via its integral thumbscrew clamp. Constructed of lightweight aerospace aluminum, with a Mil-Spec hard anodized finish, and O-ring sealed to keep out the elements, the tough M600DF will endure combat-like conditions without any sacrifice in weapon maneuverability. A slight press of the Z68 tailcap switch will activate the momentary-on, while fully depressing the tailcap until it clicks will activate constant-on. This model comes with a 18650 battery charger kit.
