This year’s most fashionable and eco- green Christmas decorating must-haves are LED holiday lights. LEDs which are short for light-emitting diodes, use the same technology fiber optic communication systems do to light up our dark Christmas days. You are probably used to seeing these lights on your car dashboard but in the last decade the technology has also been used to create Christmas decorations.
LED lights are made from two or more different semiconductor materials layered together like a sandwich. One side has a positive charge and the other a negative. When you plug these lights into an electrical source the negative and positive charges spark up to create a particle of light which does not seem to be part of the fiber they sit on. This creates photons that give them an otherworldly glow. Photons like this come in different colors which are caused by the different wavelengths. The color of the LED bud also sometimes depends on the type of semi-conductor that is used. Some LEDs have tinted caps that also help create the illusion of color as this is less expensive then using semi-conductors that create different wave lengths.
According to Philips, and other manufacturers, these “solid state” lights can last for up to 80,000 hours. There’s no filament to burn out and no glass bulb to break. Plus, LEDs use only about five percent of the energy required to power other Christmas lights. For those of us who fuss about reducing our electric bills this is great news. Of course the less power we use in general like this the less we have to worry about pollution and other problems.
LED Christmas lights cost about twice as much as mini-light strands. Depending on how many hours you plan to run them, you might see a return on the cost of them within a year. They also last years and years. They do not burn out like regular Christmas light screens which make them very economical to own.
For most of us, however, buying all new LED lights to replace perfectly good mini-lights is not going to happen because, it would be too expensive. If this is true for you just take it slow and replace your current light bulb strings as they burn out with the new LED Christmas Light Strings.
