Where to buy

Say hello to voice-controlled lighting. The RL35R headlamp is hands-free like never before, harnessing the power of cutting-edge voice-recognition technology to make versatile lighting responsive to intuitive spoken commands. Engage this game-changing voice control feature and then tell your headlamp what to do—with options for power on/off, lighting output, beam shape, beam color, and more. Ideal for hands-on work and messy environments, the RL35R makes portable lighting as dynamic and easy as possible. The RL35R also works with manual controls, including the COAST Variable Light Control dial for precise light-intensity adjustments. The headlamp shines in four colors—white, blue, green, and red—with flood and spot beam options in white mode. Independent switches control the white, blue, and green beams, and a third switch controls the white and red ARC280™ light that glows around the face of the headlamp.

At peak power, shine 1100 lumens with a 613-foot beam. Hold the center power switch down for three seconds to prevent accidental power drainage and engage the lockout. The detachable battery pack features a red rear-facing safety signal that shines in solid or flashing mode for visibility from behind. Outfitted with a USB-C in/out port, the battery can receive power or become a power bank to charge other devices.
