Viridian 4lux Mlok 400 Lumen

The Viridian 4LUX M-LOK 400 Lumen handstop light combines tactical illumination with ergonomic weapon support in a single compact unit. Designed by Viridian Weapon Technologies, this 400-lumen tactical light integrates seamlessly into modern rifle platforms via M-LOK attachment, providing operators with both forward grip functionality and high-output illumination for target identification, target engagement, and threat assessment in low-light environments.

The 4LUX generates 400 lumens of output, sufficient for illuminating tactical distances while maintaining battery efficiency. At 0.38 lbs and measuring 4.5 x 2 x 6 inches, the light balances mounting capability with minimal weight addition to the rifle platform. M-LOK mounting allows rapid integration or removal without tools, supporting modern rail systems found on AR platforms, modern sporting rifles, and tactical carbines. The handstop configuration positions the light beneath the forearm for intuitive weapon control while keeping thumb and trigger-hand position uncompromised.

Law enforcement tactical teams, military personnel, armed security operators, and sport shooters training in force-on-force scenarios rely on handstop-mounted lights to preserve weapon handling while maintaining illumination control. This configuration suits entry teams, patrol rifle operators, and defensive training environments where the shooter needs independent control of illumination separate from trigger manipulation, enabling target discrimination before engagement.

M-LOK tactical lights occupy the middle ground between lower-lumen sidearm lights and high-powered searchlight systems. The 4LUX's 400-lumen output provides actionable illumination at typical engagement distances—sufficient for identifying threats in buildings, vehicles, and outdoor tactical scenarios without excessive power consumption. Handstop mounting keeps the light accessible and prevents accidental obstruction of the shooter's primary sightline.
