"Incandescent lights last about three years, while LEDs last about ten years. " - Ryan Tague of Ace Hardware
It may seem like an easy decision when trying to save money this holiday season.
An average $7.99 for classic Christmas lights or nearly three times that for the new LED lights.
However, these seemingly cheap classics could end up costing more.
"They use more energy, and they aren't as efficient because a lot of the energy that goes into lighting the incandescent bulb is actually lost as heat," said Marc Shkolnick from Lincoln Electric System.
Incandescent or classic light bulbs can seem like the cheaper option, but over time, the cost of energy used to heat those bulbs adds up.
The packaging doesn't lie -- LED lights help save energy.
"The LED, on the other hand, uses all of the energy to light the led," said Shkolnick, "without giving off heat or using too much energy."
They also last longer than classic light bulbs.
"Incandescent lights last about three years, while LEDs last about ten years," said Ryan Tague of Ace Hardware.
But, don't be fooled, it may take awhile before customers actually see the savings that LED lights will bring.
As far as LED Christmas lights go, at $24.99 a strand and the current electric rate at an average 8.5 to 9 cents a kilowatt hour (according to LES), it could take more than a decade to make that money back.
But, saving money isn't the only benefit LED lights bring.
They are also safer, sturdier and easier to install.
"When you have lights that are putting out more heat, you could run into problems if they come into contact with something flammable," said Shkolnick.
Weighing the pros and cons, it's truly a decision customers will need to make themselves.
