One of the main reasons why LED night lights are popular because they are energy efficient.Because of the way they are constructed, they do not get heated easily and hence consume less energy. Incandescent bulbs heat up when they are in use, and this causes them to not only wear out faster but also consume larger quantities of electricity.
Because of their construction, LED night lights also last longer than ordinary bulbs. And this is not only by a few hours or days but by many years. While an average incandescent light bulb would last a few months if it is used nonstop, LED lights can last up several years.
LED are also very durable and do not contain the fragile filament that regular bulbs do.
