Holiday LEDs

Hi friends,

Christmas is a very special day for all of us. It is not only an auspicious day to do all that we had always wanted to do, but never found time to do it. Christmas is one of the seasons that we look out for in the year. It is one time where we get to meet all our family kith and kins. It is that time of the year when we get to meet a whole lot of new people and plan out for stuff that we always liked to do. Christmas is always characterized with lots of cakes, balloons, color papers, and lights. You will find the houses and carol places lit up with lights everywhere. Lights play an important role in setting the right mood for the christmas eve. The lights produce that festive mood in the place where you celebrate christmas. Christmas lights first gained importance in the 16th century, then Over a period of time, strings of Christmas lights found their way into use in places other than Christmas trees. Soon, strings of lights adorned mantles and doorways inside homes, and ran along the rafters, roof lines, and porch railings of homes and businesses. In recent times, many city skyscrapers are decorated with long mostly-vertical strings of a common theme, and are activated simultaneously in Grand Illumination ceremonies. In the mid 2000s, the video of the home of Carson Williams was widely distributed on the internet as a viral video. It garnered national attention in 2005 from The Today Show on NBC, Inside Edition and the CBS Evening News and was featured in a Miller television commercial. Williams turned his hobby into a commercial venture, and was commissioned to scale up his vision to a scale of 250,000 lights at a Denver shopping center, as well as displays in parks and zoos. White LEDs are similar to colored LEDs in most respects such as power and durability, but utilize a two-stage process to create the white (polychromatic, or broad spectrum) light. In the first stage, the LED actually only produces one color of light, similar to any other LED. In the second stage, some of the blue or violet-blue is absorbed by a phosphor which fluoresces yellow, imitating the broad spectrum of colors which our eyes perceive as "white". This is essentially the same process used in fluorescent lamps, except for the use of an LED to create blue light rather than excited gas plasma to create ultraviolet. LED Christmas lights that you find at are 85-95 and more efficient than most other standard incandescent lights and you will find that they will last for more than 50,000 hours when compared to the ordinary ones you will find in the market.
