Governor's Energy Office. U.S. Department of Energy. FS 141, Second Edition. Under each false statement, explain why it is false. The term lumen refers to actual visible light produced.
Incandescent bulbs produce more heat than light.
Dust on incandescent bulbs and fixtures does not affect the amount of light available for use. When leaving the room for only 2 to 3 minutes, it will still save energy to turn off incandescent bulbs. Fluorescent bulbs use electricity more efficiently than incandescent bulbs and produce about four times as much light per watt. Although fluorescent bulbs are more efficient, they do not last as long as incandescent bulbs. It is not possible to add fluorescent lighting to your home without totally rewiring the existing fixtures.
