Streamlight's Knucklehead LED work light features a 360° rotating head
Streamlight's Knucklehead LED work light features a 360° rotating head, and a powerful magnet and retractable hook. Available in both rechargeable and alkaline battery C4 LED models, the Knucklehead’s engineered optics feature dual parabolic reflectors within a larger textured reflector. Microprocessor-controlled technology provides multiple modes of operation, including high and low intensity, emergency flash and a long-running moonlight mode. On the high setting, the Knucklehead is engineered to deliver 1,150 candela peak beam intensity and 200 lumens measured system output, with a runtime of 3 ½ hours. On the low setting, the light is designed to provide 63 lumens and a runtime of 16 hours, and will run continuously for 20 days in moonlight mode and for eight hours on the flash setting. The two C4 power LEDs are impervious to shock.
The light’s articulating head can rotate 360°, and pivot up and down 210°. The Knucklehead features a storable hook, a removable magnet with a 135-pound pull strength and a replaceable rubber boot.
The rechargeable version of the Knucklehead operates on a nickel-cadmium 4.8-volt, four-cell sub-C battery that can be recharged up to 1,000 times, and comes with an optional four “AA” alkaline battery carrier. It is available with chargers designed for use with AC or DC power sources. The light also is available in an alkaline battery model, which uses four “AA” batteries.
Manufactured from nylon polymer that is engineered to be both chemical and corrosion resistant, the Knucklehead features a sonic-welded push-button switch and a rubber dome push-button actuator.
The Knucklehead features a polycarbonate lens with silicone anti-scratch coating set in a bezel. The lens and all other openings are O-ring sealed and are IPX4 rated for water-resistant operation. The light is impact-resistance tested to two meters.
