Fun Facts about LED Christmas Lights

Do you know that there are 45,000 brilliant lights on the Rockfeller symbolic grand Christmas tree and they are all LEDs? Let’s talk about it a little so you get to know something practical for your own holiday decoration!

LED Christmas lights are small light emitting diodes connected together by a wire. Unlike traditional miniature incandescent bulbs, they are illuminated by the movement of electrons in a semi-conductor material rather than heat causing an internal filament to glow.


In 1882, three years after Edison invented the first sensible light bulb, Edward H. Johnson created the first Christmas lights in his home in New York City. Although LEDs have been around since the 1960s, they didn't become popular in Christmas lighting until the beginning of the 21st century. Older types originally came in only red. As the technology improved, however, a wider range of colors and shapes became available.


The bulbs in LED Christmas lights are available in a great variety of shapes, from the traditional cylinders with pointed tips, to balls and cubes, to special designs that look like pine cones or snowflakes. Typical bulb types are C9, C7, C6, G12, Mini, and 5mm.

Consumers also have choices between one-piece construction and two-piece construction. In two-piece sets, lamps or bulbs can be removed from the socket and replaced. In contrast, individual lights in one-piece sets are physically molded to the lamp socket during the manufacturing process, which means lamps or bulbs are not removable or replaceable. However, one-piece is usually more durable as the sealed assembly prevents moisture penetration, loose connection and resulted damages.

Rope lights can also be applied as Christmas tree lights. They have lights and wires inside of a plastic tube.


LED bulb colors are vibrant, offering every color in the rainbow, as well as a variety of whites ranging from warm white to cool white. LEDs can be made to mimic the "warm" yellow tones of traditional incandescent bulbs, or the sharper, blue-based "cool" colors.

Knowing the Kelvin temperature, which measures whether light is warm or cool, will help you make the right choice. For a cozy, in-home color, choose white lights with a Kelvin temperature between 2700K - 3000K. Cool white LED light bulbs typically have a Kelvin temperature of 3600K - 4900K.

Unique effects

LED Christmas lights are mainly used to decorate trees, window frames, the roofline, doorways, and porch railings, and create holiday atmosphere.

LED lights offer fun technology in lighting effect, including dimming light, morphing light, and color change. With the control of the integrated circuit board, LED lights can slowly fade or flash between different colors. In our “Set of 10, 12V LED Meteor Shower Lights”, LEDs can chase down tubes to simulate the appearance of falling snow. The romantic and festive vibes it gives off is perfect for holiday season.

Energy efficiency

LED lights required less electricity to shine and are environmentally safe. Many notable displays made the switch to LED Christmas lights, including the Capitol Christmas tree in 2006 and the Rockefeller Center tree in 2007.

Remember how astonishingly high your power bill was during last year’s holiday season? LED light can save you more than 80% less power consumption. Take an action this year and make a change!
