MAXIMUM DURABILITY MEETS HANDS-FREE PRECISION

The Milwaukee 2117-21 REDLITHIUM USB 400L Neck Light is a significant evolution in personal lighting, engineered for professionals who require high-definition illumination without the discomfort or beam-instability of traditional headlamps. Utilizing TRUEVIEW™ technology, this unit delivers a consistent 400-lumen neutral white beam that ensures accurate color representation and detail—critical for identifying wire circuitry or inspecting mechanical tolerances in dark environments. The mechanical design features 130° of vertical light head rotation, allowing for precise beam placement in cramped quarters where stationary work lights cannot reach. Built to survive the harshest shop conditions, the sweat-resistant ergonomic band is chemically resistant to common jobsite solvents, while the IP54 housing ensures protection against dust and water ingress.
