With 400 Lumens of vibrant white light, our HML White attaches to a variety of standard helmets with ARC rail systems. The three operating modes: constant, momentary and strobe provide a concentrated, high-intensity beam to ll your eld of view for close to mid-range target identification. Same compact design as the HML White, the HML White/IR includes 100mW of IR output. The high efficiency emitters provide up to 1.5 hours of runtime in white mode, or 4 hours in infrared mode. Instantaneously switch between white and IR with just a flip of the lever. In addition, the easy-to-operate lockout system ensures the light isn’t activated until you’re ready.
