This LED headlamp allows the smooth transition from broad floodlight setting, for lighting the nearby environment, to a focused beam for distant targets. It offers three light intensities, 550, 200 and 20 ANSI lumens, and, thanks to its high-performance battery, guarantees an operating time of up to 63 hours. Any device with a USB port can be used to charge myStar, the USB socket of a car as well. The ergonomic head strap of the 161-gram lightweight headlamp is adjustable to fit all head sizes.
