Efficient Lighting

A 60-watt incandescent light bulb left on for 5 hours a day costs about $10 per year in energy. Switch to an 18-watt compact fluorescent light (CFL) that will provide the same amount of light at one-fourth the energy, and that cost drops to about $2 per year. For five bulbs, the savings per year is $40! And CFLs last seven to ten times longer than incandescents! LEDs (light-emitting diodes) use up to 90% less energy than incandescents and last at least 25 times longer. Using five 9-watt LEDs saves you $44 each year!

The Lighting Label provides standard information for any light (click for more details).

CFL Recycling

Several retailers throughout Snohomish County offer free recycling of compact fluorescent lamps. See link to the right.

Mercury-Containing Lights Stewardship Law has been updated

The state Legislature has updated the Mercury-Containing Lights Law (RCW 70.275). This law requires lamp manufacturers to finance the stewardship program through an environmental handling charge added to all mercury-containing lights sold at retail locations in the state. The LightRecycle Washington Program became operational on January 1, 2015. To learn more, visit
