Product Overview
The InForce helmet-mounted light is a powerful lighting solution designed for versatility and reliability. It delivers 400 lumens of vibrant white light and is specifically crafted to easily attach to a variety of standard helmets equipped with rail-capable systems.
This light undergoes rigorous testing to ensure top-tier performance, durability, and reliability in real-world scenarios. Its compact and durable design prioritizes simplicity and ease of use, allowing for easy mounting without additional tools.
The InForce HML offers three distinct operating modes—constant, momentary, and strobe—providing a versatile and adaptable lighting solution for various scenarios. These modes deliver a concentrated, high-intensity beam for close to mid-range target identification. A convenient lockout feature, activated with a 1/4 turn of the head, prevents accidental activation during travel, transport, and storage.
