Christmas lights typically use very little energy, especially when compared to other household appliances. The average set of LED Christmas lights consumes about 0.1 to 0.2 watts of electricity per bulb, which is about 10% to 20% of the energy used by traditional incandescent bulbs. This means that a set of 100 Christmas lights would use about 10 to 20 watts of electricity, which is roughly equivalent to the energy used by a single LED light bulb. Additionally, LED lights are very durable and long-lasting, so they won't need to be replaced as often as traditional bulbs
