The optical technology of Hokus Fokus is a revolution in LED-focusing technology. In cooperation with OEC Light Research Institute in Munich, Zweibrüder has developed a double-shell lens technology with spherical chip reception. Conventional lamps show a dark spot in the middle of the light cone when being defocused. Hokus Fokus, however, always provides a homogeneous light cone. The lamp is 13 cm long, made from aircraft aluminium with high-performance coating, and extremely robust. Its LED has a service life of 100,000 hours and is energised by standard batteries (3 x AAA). The light cone can be adjusted to fit any requirement.
