The Lagerstrom family’s obsession with Christmas lights started back in 2002 with 4,000 lights. This year they plan 45,000. And the Lagerstroms, from Canada’s British Columbia, don’t plan to stop there, with an ultimate goal of 250,000 lights. They also are in the process of switching to LEDs, which will lower their costs as we estimate here.

  • Estimated cost (this year, if all incandescent): $17/hour; 4 hours a night for 30 days comes out to $2,040.
  • Estimated cost using all LEDs: $2/hour or $240 for the month.
  • Possible electric bill savings: $15/hour or $1,800 for the month.
