Hokkaido lighthouse gets powerful LEDs in beacon trial

The Japan Coast Guard has begun experimenting with high-output LEDs for the beacon of the Kushiro Saki Lighthouse here in an energy- and cost-saving test. If successful, the coast guard plans to put the high-intensity chip-on-board LEDs, which are strips of LEDs that are illuminated together, into practical use as a light source. Conventional LED lamps, which have an illumination range of 12 nautical miles (about 22 kilometers), have been gradually introduced at small lighthouses.
