Headlamps - hands-free illumination
The basic advantages of headlamps are obvious: your hands are free and you have light exactly where you look. But many headlamps are also extremely powerful, with illumination values of up to 1500 lumens and more that disqualify them for use in traffic. However, when a bright beam is essential, whether that's for caving or night riding, these lamps really come into their own. Some models are also combinable with a helmet.
