LED light bulb offer a modern life

Technology has definitely made things more efficient and effective. And thanks to it lighting has also become more advanced. LED lights and LED light bulbs are one of the latest additions in environment friendly products. These lights are made keeping in mind the deterioration of our environment done by man made products and activities. LED reduce greenhouse gas emissions .Not many people are aware of these lights except few early adopters and enthusiasts.

They use a lot less energy than other bulbs; a nine-watt LED bulb puts out the same light as a 60-watt incandescent. Above all, they last forever; 30,000 hours is typical. Compare that with 1,000 hours for regular bulbs, or 8,000 for compact fluorescents.

A bit more on economics: an Edison bulb (and all other pre-20th century light sources) is essentially a heat source that produces a little bit of light. A “65 Watt” Edison bulb produces about 700 lumens (a lumen, “lm”, is a unit of visible light power). If you had perfect conversion of electricity into visible light, you would need only 1.0 Watt (“W”) of electrical power to produce 700 lm. So, an Edison bulb is 1.6% efficient. For such a widely deployed technology, this is amazingly bad. But Edison bulbs are much better than the kerosene lamps they replaced …

An LED bulb typically goes for $30 or $40. Now, you’ll make that money back in just a few years, thanks to your savings in electricity and replacement bulbs. But you know Americans. Most people have a hard time getting their heads around long-term savings, so they usually balk at spending $20 for one bulb.

If you are looking for a higher efficient light bulb, then do not forget the LED light bulb. Thanks to the advanced technology, now, the price is much cheaper. anty881209wong 140225
