How many lightbulbs does it take to change the world? In this case, just one.
Lighting accounts for one fifth of the world’s total electricity consumption. By creating the most energy-efficient LED lamp prototype ever at 200 lumens per watt, Philips hopes to cut business and household lighting bills by at least half. This innovation, which produces warm white light, is a huge leap forward from today’s standards: it’s twice as efficient as current fluorescent lighting and more than 10 times as efficient as a traditional light bulb. Philips expects to launch the lamp in 2015.
