With 400 lumens of vibrant white light, our WML Series is ultra-compact, durable, and offers three operating modes: constant, momentary and strobe. Extensively tested for performance, durability and reliability, its high efficiency emitters provide up to 1.5 hours of runtime in white mode, or 4 hours in infrared mode. This 3-ounce weapon light's concentrated, high-intensity beam fills your field of view for close to mid-range target identification. With just a flip of the lever, instantaneously switch between white or infrared mode. In addition, the easy-to-operate lockout system ensures the light isn't activated until you're ready. Our all-inclusive rail clamping design integrates seamlessly with your weapon, providing simple, fast mounting with no need for additional tools.
