How many lights do I need for a 7 ft. tree?

For a full, balanced look, plan on using about 10 to 15 feet of lights for every vertical foot of tree height. That means a 7 ft. tree typically needs between 70 and 105 feet of lights, depending on how dense you want the coverage.

My Christmas lights are flickering! What can I do?

A loose connection or a burned-out bulb causes most flickering problems. Check for loose connections in the string and then replace any burnt-out bulbs. If that doesn't work, you might have a damaged string, and a new string is probably the best fix.
