Accidental invention points to end of light bulbs
Regular readers of Treehugger know that they go all ga-ga over LED lighting. So I was surprised not to find a post about this:
An accidental discovery announced this week has taken LED lighting to a new level, suggesting it could soon offer a cheaper, longer-lasting alternative to the traditional light bulb. The miniature breakthrough adds to a growing trend that is likely to eventually make Thomas Edison’s bright invention obsolete.
Read the short article over at LiveScience.com to learn about the science behind the accident. On why this is of interest to enviros:
LEDs produce twice as much light as a regular 60 watt bulb and burn for over 50,000 hours. The Department of Energy estimates LED lighting could reduce U.S. energy consumption for lighting by 29 percent by 2025. LEDs don’t emit heat, so they’re also more energy efficient. And they’re much harder to break.
