Head Fire Duplex is a masterpiece without compare, beautifully designed and full of inner qualities that simply outshine other head lamps. Its big swivel tube is equipped with a super-bright 1W high-output chip, whose computer-calculated widerange collimator focuses the beam with undreamt-of power. Its small tube with aspherical lens is ideal for reading and illuminating objects within short distances. Its housing is spray-water-proofed.
