LED Holiday Lights
LEDs consume far less electricity than incandescent bulbs, and decorative LED light strings such as Christmas tree lights are no different. Not only do LED holiday lights consume less electricity, they also have the following advantages:
Safer: LEDs are much cooler than incandescent lights, reducing the risk of combustion or burnt fingers.
Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage.
Longer lasting: The same LED string could still be in use 40 holiday seasons from now.
Easier to install: Up to 25 strings of LEDs can be connected end-to-end without overloading a wall socket.
