Royal Philips Electronics has unveiled its 12W Endura LED light bulb, a replacement for a 60W incandescent light bulb. The company said that new LED alternative to the commonly used incandescent bulb, will deliver up to 80% energy savings and last 25 times longer than its predecessor.

Exceeding the Energy Star specifications for a 60W bulb, the Endura LED uses 12W of power while delivering 806 lumens.

According to calculations by Philips, this LED replacement has the potential to save 32.6 terawatt-hours of electricity in one year, enough to power the lights of 16.7 million US households or 14.4% of the total number of households in the US. It is expected to eliminate 5.3 million metric tons of carbon emissions annually.

The new lamp uses a new design and remote phosphor technology to deliver the same soft white light and shape consumers are familiar with in an incandescent. The Endura LED works with standard dimmers, further simplifying use and allowing consumers to enjoy low energy lighting in the home.

Expanding on the Philips Endura LED family of replacement lighting, the new lamp has a rated life of 25,000 hours, as opposed to a standard 60W incandescent bulb which is rated at about 1,000 hours.

This means that over the course of the LED life, replacing a 60W standard bulb could save a business or household $120 per lamp, the company said. It will be available in the US in the fourth quarter of 2010.
