Christmas lights are small lights most often utilized for decoration on display during Christmas, particularly during Advent and Christmas. The tradition actually goes way back when Christmas trees were first decorated with elaborate candles, that symbolized the fact that Christ was the true light of the world. Since candles eventually gave out so much heat, early settlers built huts around their trees to collect the heating energy, and store it for use in their homes during colder months. As time passed by, neighbors began wiring Christmas lights into long strings that were hung on walls and fences, and to add to the festive look of the season, stockings were also hung at doorsteps and windows to dangle on string cables, with the center being a candle. These lights became known as lanterns and marked the beginning of lantern pole lighting for Christmas.
Another similar tradition was the so called Christmas lights grid system, that was utilized primarily to draw attention to homes and buildings. The grid system was made up of rectangular, four by six feet lights, that were connected to four by six feet long light bulbs, that lit up in a circle. One of the biggest problems with this system was that the wires that the lights were hung upon had to be hidden under bushes and shrubs, otherwise the lines would have been exposed and could have caused accidents. When Christmas lights moved indoors, instead of running along the floor of a building, they were mounted onto the wall, and lit up the entire room. The original Christmas lights grid system relied on oil-glazed paperboard, with the lights gliding along the boards.
Today’s LED Christmas lights are similar to the grid system, except they are designed to run in an electric current, instead of relying on oil or paperboard. LED Christmas lights offer many benefits over their incandescent counterparts, such as lower energy consumption and a lower chance of fire. They also last longer than incandescent bulbs, up to forty years or more, and run much cooler than the latter. Incandescent lights have also become less popular over time.
