Ho ho ho! Lighting a Christmas tree is a wonderful way to bring the holiday spirit into your home. There are many different ways to do this, depending on the type of tree you have. If you have an artificial tree, you can simply plug it into an outlet and turn it on. If you have a live tree, you'll need to use Christmas lights. You can use traditional incandescent lights or LED lights, which are more energy efficient and don't get as hot. Just make sure to follow all safety guidelines when using lights on your tree!
