LED bulbs can last 10 times longer than traditional glass bulbs and don't need to be replaced as often.
Safety
LED lights don't produce as much heat as incandescent lights. Not only are they cool to the touch, but they are also less likely to cause a fire,
Performance in cold weather
LED lights perform better in cold temperatures, often shining brighter and using even less energy.
