Over the years the uses for LED lighting has grown. Studies have indicated that they provide a significant savings in cost as well as saving on energy. One can find the lighting in many different types of products such as lamps, traffic lights and outdoor LED signs. They have even been used in infrared LED therapy, which claim to help reduce pain.

The discovery of LED dates back as far as 1907, but it was not officially recorded until 1927. The diodes continued to be studied, as at the time, there was no usable interest in them. Finally, in 1968, it began showing up as more light indicators in handheld calculators. The cost for making this type of technology was quite expensive, so there was no real demand for it. However, they continued to work on its development

The first practical use of LED was as a replacement for regular and neon light bulbs in primarily in the lab. Later it found its way into the home appliances such as televisions, radios, telephones and even wristwatches. Although at that time it was still only used as indicator lights. It was not bright enough to light up an area.

The scientists did not give up though. They continued to study and work with it and eventually there were several colors in the spectrum. After time, a white light was found that was much brighter than the others. This combination of light could actually light up an entire room. Now the light bulbs that Thomas Edison discovered years before are being replaced with this much brighter light.

Today one can find these lights in all kinds of places. They are used in lanterns, car lights, or flashlights as well as many other items in our homes. By being able to move the light beams in a steady line, can create a very bright light beam. For this reason alone, they are very much in demand in flashlights. The lights are very environmental friendly as well as big money saver.

Today these lights can be found in any number of every day objects. One of the most popular uses today is Christmas lights. These have become almost all LEDs now. Now a large number of tv sets are made with LEDs. They project through a LCD screen and create a almost perfect picture.

They look much brighter and clearer. These days, LED lighting everywhere. The old neon signs out at bars, hotels, and other places have been replace with outdoor LED signs clearer to the eye. Anyone who wants to have his or her business signs noticed is turning to LED
