Japan’s leading retailer of electric appliances, Yamada Denki, has launched LED lighting that incorporates a
lithium-ion battery for offices and outlets. The new lighting system uses the
conventional power source and the built-in battery alternately and can save
energy consumption by 40% as compared with the existing LED lighting. In
addition, it can be an emergency light during a power failure. Developed by
CyberCoin, the new light system is named Everluce and sold exclusively by
Yamada Denki.
Everluce starts to
charge the built-in lithium-ion battery and finishes charging in three hours.
Once the lithium-ion battery is fully charged, only the lithium-ion battery
lights Everluce for two hours. This mechanism reduces power consumption. Yamada
first put an Everluce that has the same brightness as 40 W. It has the power
consumption per hour of 15 W on average, about 40% lower than the existing LED
lighting. It will turn into an emergency light that illuminates for 12 hours in
power outage. Everluce is priced at 19,800 yen each, twice as much as the
existing LED on the market, and rented for a monthly fee of 300 yen. Yamada
Denki plans to sell 1 million Everluces in 2015.
