The EverLed series of light bulbs, scheduled to be released in Japan on October 21, are the most efficient LEDs to ever be produced. If used 5.5 hours a day, the bulbs could theoretically run for 19 years.
So when you get married and have a kid, the day he starts drinking in Canada you're going to need new lights. Not a bad run. The new Panasonic EverLed light bulbs are only available in Japan and cost around 40 dollars (4,000 Yen).
