LED technology has been developing very rapidly lately, and it’s nearing the point where we’ll be using LED-based lightbulbs for most of the lighting in our homes. ISuppli, a semiconductor research company have predicted a growth in their LED lights sales for the next three years that goes into the double digits.

Seven Eleven Japan, the convenience store plans to equip all its new stores with LED-based signboards and outdoor lighting. The effort is to reduce emissions of global warming gases. LEDs will likely be able to allow 7-11 to cut its carbon dioxide emissions by 3%, or 1.8 tons per store per year times 1000 new stores each year.

The Seven & i Holdings Co. estimates that it will spend more than 1 billion yen a year on LED lighting. An initial investment per new store will cost 1-2 million yen. Down the road, Seven-Eleven Japan is expected to use roughly 75% less power than fluorescent lights, thus getting back their investment. LED lights also last four to five years, compared with a year or so for fluorescent lights.

Rival convenience store operators, Lawson Inc., FamilyMart Co. and Circle K Sunkus Co. have been testing LED-based signboards, however, 7-11 is the first to take the plunge on a large scale.

Convenience store operators are also turning to more power-efficient air conditioning to reduce their CO2 emissions.

Shall we call this a convenient truth?
