Rust is another factor in your choosing non-replaceable LED Christmas lights rather than the standard string of Christmas bulb lights. Copper wiring in standard cords can rust. If any moisture gets into the bulb environment whether actual water or just condensation it will begin to rust. This rusting takes place very quickly. In a few months, you'll have a Christmas light bulb that falls right out of its light socket. A non-replaceable led Christmas light, however, is totally watertight. You just can't get any moisture into it. The result is that it never rusts.

LED Christmas lights use only a fraction of the lighting energy as standard bulbs. Rather than 350 watts for a standard set of 70 Christmas lights at five watts each, LED Christmas lights use less than four watts total for all 70. This represents at least a 90 percent savings in electricity. If, for example, you were to use five strings of LED Christmas lights each with 70 lights and you left the lights on 8 hours a day for 7 days a week, and the rate you pay for your electricity is the national average of 8 cents, you'll save $33 a month by using LED Christmas lights.

While you may pay more for LED Christmas lights than the standard holiday bulbs, they'll more than pay for themselves the first holiday season.

They come in such pretty holiday colors and styles, too. One vendor offers three choices of each. The styles are strawberry, razzberry and mini-ice, while the color choices are multi-colored, winter white, blue sapphire, ruby, green, orange and gold.

LED Christmas lights are made of epoxy plastic which is solid, flameproof and unbreakable. They don't get hot like traditional Christmas bulbs, so they're safe indoors or outdoors, and you won't have to worry about your dry tree branches. The patent on these LED Christmas lights has prepared them for your standard electric outlet. You can even exchange them or interchange them with your traditional Christmas lights.

LED Christmas lights are made from miniscule sized chips that are solid state and like those in computers. The chips convert electricity into light but don't need any filament or bulb to accomplish this. The lack of filament is what keeps them burning and keeps them cool.

The unusual shape of LED Christmas lights makes them beautiful, giving off a shimmer when lighted. If you view your LED Christmas lights from two different angles you'll get two different decorative views.
