With 400 lumens of vibrant white light, Inforce's WML Series is ultra-compact, and 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. This 3-ounce weapon light's concentrated, high-intensity beam fills your field of view for close to mid-range target identification. The strobe function is easily disabled and the easy-to-operate logout system ensures the light isn't turned on 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.
