Avista Offers Tips for Keeping Holiday Lighting Affordable and Safe
New energy efficient holiday LED lights use less energy and can add less than a penny a day to your energy bill

SPOKANE, Wash. - Dec. 7, 2006 : Avista suggests using energy efficient lights when decorating for the holidays to help manage your energy bill and conserve electricity. Also, always keep safety in mind when installing any holiday lighting.

The use of 500 traditional holiday bulbs, labeled C-7 or C-9, for five hours per day for 30 days can add around $35 to your Avista energy bill. The same number of mini-lights can reduce that cost by approximately 90% for the same time period. But, switching to LED holiday lights can bring the most energy savings – adding only about 20 cents to an Avista energy bill and reducing the amount of electricity used by approximately 522 kilowatt-hours.

The chart below provides a comparison of holiday lighting for Avista residential customers using 500 holiday lights for five hours per day for 30 days.

According to a recent U.S. Department of Energy report, replacing all traditional holiday lights (C-7 and C-9) in the United States with LED lights would save approximately two billion kilowatt-hours (kWh). That’s enough to power nearly 200,000 homes for an entire year.

When installing holiday lights, keep the following safety tips in mind:

  • Watch for overhead powerlines when installing outdoor lights.
  • Check lights for broken or cracked sockets, frayed or bare wires, or loose connections. Discard damaged sets.
  • Do not overload outlets or extension cords.
