Viridian 4Lux Close Quarters Grip Weapon Light 400 Lumen Ergonomic M-L

The Viridian 4Lux Close Quarters Grip Weapon Light brings dedicated low-to-medium-distance illumination and ergonomic control together in a single M-LOK-compatible package. Built for shooters who need a foregrip that doubles as a tactical light—whether you're running an AR-15, AK-pattern rifle, or M-LOK-equipped shotgun—this 400 lumen light delivers the flood-heavy beam pattern you want when targets are close and room clearance demands speed over reach. The foregrip design prioritizes shooter control and recoil management, while the activation system keeps the light under your thumb, where it belongs.

Viridian engineered the 4Lux around the reality of close-quarters work: a wide, even beam that illuminates your immediate workspace without the narrow throw of a distant-target spotlight. That matters when you're moving through structures or tight cover, or when you need to identify threats and engage quickly at indoor distances. The 90-minute runtime means you can train or deploy without constantly hunting for a recharge, and the robust, weather-resistant construction handles the wear of regular use.

Made in Minnesota, the 4Lux combines American manufacturing with the kind of uncluttered design that works. No complicated battery doors or confusing interfaces—just a foregrip you mount to your handguard, solid ergonomics, and a light that does what it's supposed to do when you need it. If your rifle work happens close and your setup uses M-LOK, this is a straightforward choice.

Frequently Asked Questions

Will the Viridian 4Lux fit my rifle or shotgun?

Yes, if your firearm has an M-LOK handguard slot. The light is engineered to work with AR-15s, AK-pattern rifles, tactical shotguns, and any other platform that uses M-LOK rail space. Standard Picatinny rails are not compatible.

What's the beam pattern like compared to long-range weapon lights?

The 4Lux uses a wide floodlight lens designed specifically for close-quarters situations. It's built to illuminate your immediate work area evenly rather than throwing a narrow beam downrange—ideal for room work, short-distance rapid target engagement, and training at typical indoor distances.

How long does the battery last during a training session or deployment?

The 4Lux delivers 90 minutes of runtime, which covers most training scenarios and tactical use without requiring a mid-session recharge.

Is this a true foregrip or just a light with a grip-shaped body?

It's a full ergonomic foregrip first—the design helps with recoil control and weapon manipulation. The 400 lumen light is integrated into the grip so you get both functions, not a compromise of either.
