The Streamlight Double Clutch USB, is a 4 oz, compact, low-profile LED headlamp that is USB rechargeable, with optional battery back-up. This light features both spot and flood beams -- for either distance or close-up lighting needs -- and provides high- and low-intensity settings for each beam mode. This light offers a 60-degree tilting head to reduce neck fatigue and a “glove friendly,” easily rotated face cap for shifting between modes, and turning the light on and off. The light features durable polymer construction, is IPX4 rated for water-resistance, and is impact-resistance tested to 2 meters. Available in yellow or black, the headlamp comes with both an adjustable elastic head strap and a rubber hard hat strap.
