The new Streamlight® Knucklehead® flashlight is specifically designed to become the best and most-used tool in your toolbox. Besides the extra strong magnet located on the back of the light, it also features a 210 degree articulating head that rotates 360 degrees so you can point the light in virtually any direction while the body of the flashlight stays in one position. The dual C4 LEDs are placed to provide a smooth flood pattern in the textured reflector, which does away with the typical "hot spot" in the beam. The Knucklehead® has 4 modes, high (200 lumens), low (63 lumens), moonlight (20 day runtime), and strobe (8 hour runtime). It utilizes the Streamlight® Survivor LED® chargers, and each one comes with an alkaline battery case as a back-up power source. It is available in black or yellow and comes with Streamlight's limited lifetime warranty. I must add that I have personally tested out this light and I am quite impressed with it!
