The Double Clutch USB is a USB-rechargeable, multi-fuel headlamp with switchable spot and flood beams, suited to professional users who need adaptable, hands-free lighting. Powered by a USB-rechargeable lithium polymer battery, the Double Clutch USB also accepts three AAA alkaline or lithium back-up batteries so the power source can be matched to the task. A quick twist of the facecap turns the light on and off, or changes the output from spot to flood. On High it delivers 125 lumens, with a spot beam of 1,700 candela reaching 82 m or a flood beam of 250 candela reaching 31 m. On Low it delivers 30 lumens, with 400 candela reaching 40 m in spot or 70 candela reaching 4 m in flood. Run time is 3.5 hours on High and 10 hours on Low from the lithium polymer battery, or 6 hours and 18 hours respectively on AAA alkaline batteries. The headlamp is IPX4 water-resistant, impact resistance tested to 2 m, measures 6.35 cm (2.5 in) in length, and weighs 105 g (3.7 oz) with the lithium polymer battery or 119 g (4.2 oz) with alkaline batteries. Key features Multi-fuel power — Runs on a USB-rechargeable lithium polymer battery, or three AAA alkaline or lithium back-up batteries. Spot and flood beams — Produces 125 lumens on High and 30 lumens on Low, switching between a focused spot beam and a wide flood beam. Twist-facecap control — A single twist of the facecap turns the light on and off, or changes the output from spot to flood. Water and impact resistant — Rated IPX4 water-resistant and impact resistance tested to 2 m. Durable housing — Built with a tough polycarbonate construction and a polycarbonate lens. Compact and lightweight — Measures 6.35 cm (2.5 in) in length and weighs 105 g (3.7 oz) with the lithium polymer battery. Complete kit — Supplied with rubber and elastic head straps, a USB cord and a rechargeable lithium polymer battery. Typical applications Hands-free lighting for technicians and engineers working in confined spaces. Outdoor and field tasks that call for both close-up flood lighting and longer-range spot lighting. General workshop or household use where a lightweight, head-worn light is convenient.
