The 130-year old Edison light bulb is finally getting an upgraydd.  Consumers can now purchase bulbs that use light emitting diodes (LEDs) that produce 40 watts worth of light on only 8.5 watts, lasts up to 23 years and costs less than 25% annually in electricity.  From USA Today:

Quite a few companies have announced LED replacements for the traditional 60-watt incandescent — America’s best-selling bulb. They include Cree, Lighting Science Group, Royal Philips Electronics and Osram Sylvania.
The Home Depot now sells a 40-watt equivalent EcoSmart LED for about $18, and Lowe’s retails a similar LED by Osram Sylvania for about $15. Beginning next month, Lowe’s will sell a similar-wattage LED by General Electric.

Happy Earf Day!
