Signify, a Dutch lighting company, has launched the Philips Ultra Efficient LED bulbs that use 40 percent less energy than its regular LED bulbs. The new LEDs are designed to reduce the yearly energy cost to between 55 cents and $1.03 per bulb. Signify claims that the “advanced” LEDs and optics, used in the Ultra Efficient line, will reduce energy consumption and waste. The new line is expected to have a lifespan of 50 years, which is more than three times the usage of Philips’ standard LED bulbs.
