New LED Light Bulbs Can Replace 100W Incandescents

MetaEfficient.com

...LED bulbs have many advantages over incandescents and compact fluorescent: they use very little power, they last 10 years or more, and they contain no hazardous substances. They are also tough: they can be dropped and turned off and on repeated without damage, they can operate in very cold or warm temperatures.

LED bulbs can also save you money in the long term, because an incandescent bulb requires about $300 worth of electricity over ten years of use. The LED bulbs cost $50 (for the 100 watt equivalent Evolux) and $90 (for the 60 watt equivalent Zetalux), and their cost to run over ten years is about $38...

Use LED holiday lights

The bulbs can last up to 50,000 hours (that’s over five years of continuous lighting — no more tweaking every bulb trying to find the dud!) and use up to 90% less energy than standard incandescent bulbs. One estimate puts the potential savings at over $8 for just one tree’s worth of lights!

Super efficient LED lights now available for the home

LED lighting technology, based on semiconductor technology, is the future of lighting. It uses a fraction of the energy of traditional lightbulbs. The LED lights can last 20 years of regular use meaning over time they easily pay for themselves. The problem has been that LEDs have not generated enough lumens (a measure of brightness) to be worth using in homes. That problem, however, is being solved.

A retrofitted LED bulb fixture is now available to replace traditional spotlights in the home. The fixture can easily replace what you have now without using an electrician. The bulb generates 650 lumens with only 12 watts. An incandescent bulb uses 5x that amount to produce the same amount of light.

LEDs are better than compact flourescent lightbulbs because they last much much longer and CFCs are made with mercury which probably will be released into the environment once they are disposed of. LEDs also emit a more pleasant and natural light than CFCs.
