The premier application of the K2 Luxeon LED is its incorporation into the new Headstream Headlamp. Using a sophisticated optical collimator, the intense K2 Luxeon light is focused into a tight, optimized beam. A responsive digital switch on the top enables easy control of light from high to low, and the pivoting head can readily adjust to any projection angle. A slim separate battery case at the back of the head doubles as a rear safety light that can be either a constant red light or flashing emergency

The K2 Luxeon LED housed in the HeadStream is extremely powerful, with a sophisticated light focusing design that results in a maximum brightness of 85 lumens. Uses Digital switching from high to low power, and direct switch off from any mode.
Water resistant. Integrated rear safety light with constant-on or flashing functions.
