Christmas lights, or twinkle lights, come in a variety of shapes, sizes, and colors, and add a festive and bright look to any Christmas celebration or holiday season. Common Christmas lights come in sets of two or three strings and include incandescent bulbs that may be white or colored, and often feature a star or other decorative detail at the top of each bulb. Some Christmas lights are known as “net lights” as they form a covering over the area of display. This netting is held in place by white or green wires, and the lights can give a uniform look when viewed from a distance. LED Christmas lights are more energy efficient than traditional incandescent lights and do not burn out as quickly. They come in a range of colors and sizes, and often have features such as twinkle, fading, and color changing effects. Christmas lights can be used in many ways to enhance the holiday season, such as decorating a Christmas tree, home exterior, or window display. Whether miniature, standard, or the extra-long strands, anyone can enjoy a festive display of bright Christmas lights, bringing cheer and beauty to the holidays.
