Take the time to go around your house and unscrew lightbulbs to give them a good dusting. Dust that builds up on top of lightbulbs can be a safety hazard if sparks fly, but more commonly the dust covering limits the amount of light the bulb emits. The EPA estimates a coating of dust on a lightbulb can reduce light output by as much as 50%. For maximum light output and safety, make it part of your regular household cleaning routine to give all of your lightbulbs a thorough dusting!
