When you need powerful lighting for outdoor endurance activities, the Petzl MYO Headlamp lights the way. Customizable illumination provides options for standard or constant lighting modes that shine from 60 to 280 lumens. For times when you need all the power you can get, switch to Boost mode for temporary access to maxed-out 370 lumen lighting. The Wide Angle lens offers flood lighting to enhance peripheral vision, and can easily be switched to a focused beam for long-range vision. Strobe mode helps keep you safe out on the roads, while an indicator light warns you when the batteries need to be replaced.
