The Viridian 4LUX M-LOK 400 lumen tactical weapon light merges a high-output illumination tool with an ergonomic foregrip to give you reliable light and control in one package. Built for shooters running AR-15s, AK-47s, tactical shotguns, or any rifle with an M-LOK handguard, this light puts a combat-rated beam exactly where you need it without forcing you to choose between grip stability and tactical visibility.
The 4LUX delivers a specialized close-quarters beam pattern—LED and floodlight lens design work together to illuminate targets and environments without the tunnel effect of narrow-beam spotlights. Grip-activated controls let you fire up the light on demand, keeping your shooting hand in control and your finger indexed naturally. The foregrip itself is purpose-built to help manage recoil and support consistent weapon manipulation, making it genuinely useful whether you're running low-light home defense drills, tactical courses, or duty applications.
Built tough in Minnesota, the 4LUX is engineered to survive hard use. It runs for 90 minutes on a charge and shrugs off impact and weather. This is a weapon light that works when conditions are bad and your margin for error is small.

The 4LUX mounts on any firearm with an M-LOK handguard slot, including AR-15s, AK-47s, and tactical shotguns. Check your rifle's foregrip to confirm M-LOK compatibility.
The 4LUX delivers 90 minutes of runtime per charge.
It's both. The 4LUX is designed as an integrated package: an ergonomic foregrip that doubles as a high-output weapon light. The grip helps you manage recoil and control your rifle, while the 400-lumen output handles illumination duties in low-light scenarios.
The 4LUX uses grip activation—the light comes on when you depress the control located on the foregrip, keeping your hands in a natural shooting position.
