I just used my kill-a-watt power meter to figure out that my outside Christmas lights are drawing 9 amps. Quick math suggests that about 8 cents an hour to run. If I run them for 8 hours a day (morning and night), that's 64 cents a day. 35 days from today is January 1st. That's $22.40. Not bad for non-LED bulbs!#
