In 2007, we thought LEDs, or light emitting diodes, were going to be mainstream REALLY soon, and it didn't happen.
Most recently, however, we have seen significant progress addressing issues such as cost, light intensity, and bulb diversification as well as replacement lights for existing fixtures.
Thanks to the semiconductor industry the LEDs advanced rapidly. The timing is more than ever right for these bulbs: Consumers are demanding more effiecient and environmntally safer products due to concerns with rising energy costs and global warming.
Governments are imposing higher energy standards and more money is invested in reseach.
LEDs are superior due to several reasons:
1. They generate more light far more efficiently than incandescent ones, because they do not generate any heat.
2. They are as efficient as CFLs, but unlike CFLs, they can typically be used with a dimmer, and they do not contain mercury, a hazardous substance.
3. Lately LED lights are closer to providing light with a warm glow.
4. They are more reliable and durable than CFLs or incandescent bulbs.
LEDs are now available for recessed down lights, task lighting, such as under cabinet lights and desk lamps and many other types of fixture.
Major corporations are entering LEDs into the consumer market:
Philips EnduraLED is designed to last 15000hours, with a 3-year life wrranty.
i-saveenergy.com has many diffrent fixtures and replacement bulbs . I have seen the recessed lights first hand and they are beautiful and have a wonderful glow similar to sunlight.
Lighting Science Group introduced the new ultra-effiecient LED replacement bulbs in May 2010.
Prices could run $20-$60 per bulb, but they make up by lasting longer than other types of bulbs in energy usage.
Consider LEDs for your next lighting application or replacement bulbs, they pay off in the long run.
