Types of Christmas Tree Lights: LED Lights
As far as I can figure, there are five types of Christmas tree lights: LED lights, miniature lights, microlights, C7 and C9 lights (I call them "old school") and bubble lights. And most of them come in different sizes and colors.
LED stands for light-emitting diodes. According to the experts, LED Christmas tree lights use 80-85% less electricity than the other kinds of lights. It gives off no heat and is flame proof as well as fire proof.
When this technology first became available in Christmas tree light form, the lights were so bright that it hurt your eyes to even look at your Christmas tree, but sometime in the mid-80's manufacturers found a way to soften the glow.
Most of the LED lights that I am familiar with were shaped like pencil erasers -- round colorful niblets. Nowdays you can find them made with bulbs that look like fairy lights, snowflakes, round globes, stars, pine cones, ice cubes, raspberries or even to look like the old school big strawberry shaped bulbs. And you can find them in the traditional colors, as well as purple, hot pink and champagne.
Probably the best thing about the LED Christmas tree lights is that they do not contain the delicate filaments that the incandescent bulbs do, which makes the sturdier and less prone to going out.
