Christmas lights work great with or without a timer. The timer stays on for 6 hours and off for 18 hours and there are 8 different lighting combinations. It uses 3 AA batteries and looks like I only need to change batteries once during the Christmas season. I live in Florida so it's not very cold at night, no doubt a colder climate will drain batteries faster. I recommend and may buy another set next year.
