Outdoor lighting

The technology uses 230V powerlines to transmit control signals. However, unlike traditional LON-based powerline communication, SEAK technology is based on harmonious half-sine wave voltage reduction at speed of 50Hz to generate coded words. That makes it an outstanding method at signal distribution on long distances and especially in questionable mains environment.
