Inforce's WML White Gen2 light is ultra-compact, durable and offers three operating modes: constant, momentary, and strobe. The high efficiency emitters provide up to 1.5 hours of runtime. The high-intensity beam fills your field of view for close to mid-range target identification. The integrated clamping design allows for seamless MIL-STD-1913 mounting on your weapon with no tools. Its easy-to-operate lockout mode ensures the light isn't turned on until you're ready. Includes one Lithium CR123A battery.
