This headlight clips easily to any cap with two clips and keeps your hands free. Moreover, with the telescopic zoom design, it can match your different needs. The beam can be pivoted up and down as well as zoomed. Powered by 3*AAA battery(not included) for approx 2-3 hours of stabel light.
When attached to a hat and turned on, the beam of light from the LED lamp can be changed to fit any need. Keeping the zoom at its default setting, the beam of light will be a strong, bright focussed light, however, if the zoom is pushed out, the focus becomes wider and lights a larger area.
