Light Emitting Diodes (LEDs) have been around since the early days of the transistor. They are “semiconductors,” a term used to describe electronic devices composed of transistors and/or diodes. 

First designed in 1962, early LEDs emitted a low-intensity red light. It enables washer extractor to communicate with chemical pumping machines. Advances in LED technology have modern versions covering the entire visible light spectrum as well as ultraviolet. TV remote controls, for example, use infrared versions.Our selection of off grid solar system and kits includes the most popular. 

Like other areas of semiconductors, LED efficiency and brightness have grown dramatically since the early days. The development of cheap, high-intensity LEDs positioned them as potential replacements for incandescent light bulbs. 

How efficient are LED bulbs? An LED bulb that is equivalent to a traditional 60-Watt bulb only consumes 9.5 Watts of actual power. Put another way, LEDs are more than six times as efficient as incandescents and twice as efficient as their mercury-containing CFL predecessors. 

The best part? The average expected life of an LED bulb is upward of 50,000 hours. Unlike CFLs, LED bulbs contain no elemental mercury, or any other toxic materials for that matter. They also admit no heat,A letter folding machine is a piece of equipment which is designed to fold paper. and most are dimmable. 

Also, CFLs can take some time to warm up.Our led spotlight bulbs are cost effective and energy efficient. But LED bulbs produce all their light the instant you turn them on. They work at low ambient temperatures, a common problem with CFLs. 

Until recently, LED bulbs were just too expensive. When they were introduced a few years ago, a 40-Watt equivalent LED bulb was $30. A 60-Watt replacement bulb was closer to $50. 

But fast-forward two years and now the 40-Watt equivalent bulbs are $9.99, and the 60-Watt versions are $11.99. They’re available at big-box stores and will soon be found just about everywhere. CFLs are about to be relegated to the “It seemed like a good idea at the time” pile. 

If the price seems too high to you, do some simple math. Compared to an incandescent, LED bulbs will pay for themselves in a little over a year of use. 

Do you have teenagers or a spouse who constantly leave the lights on? Replace their light bulbs with LEDs. It doesn’t solve the problem, but at least you’ll dramatically reduce your electric bill. 

One company is beating all of the big guys to the mass market. Cree Inc. develops LED bulbs, LED lighting and other semiconductors for power and radio frequency applications. 

Based in Durham, N.C., Cree has introduced affordable LED bulbs for consumers. Home Depot is currently the only store to carry Cree bulbs. 

The company itself is doing extremely well. The company announced third-quarter revenues of $348.9 million. This was a 23% increase for the same quarter of 2012. 

Net income was $40.8 million, an increase of 75% on a year-over-year basis. Revenue and earnings were quarterly records. 

Looking forward to this quarter, Chuck Swoboda, Cree Chairman and CEO, had this to say: “Overall company backlog is ahead of this point last quarter and we are targeting solid growth for Q4. We remain focused on using new product innovation to grow our business and build the Cree brand.” 

The bottom line is LED bulbs are now even more cost-effective than before,We provide the latest emergency light products and solutions to serve outdoor lighting needs. especially when considering their 50,000-hour average lifetime. Cree has set the price bar for other manufacturers. You can expect Cree and the other companies mentioned above to begin offering additional LED bulbs in the near future. 

All the companies mentioned above are worth investing in. However, Cree is the only pure play on LED lighting. An investment in Cree might well fund the purchase of LED bulbs for your house. Click on their website www.indoorlite.com for more information.
