ENN News Story - Energy-efficient lighting comes of age
Americans spend about one-quarter of our electricity budget on lighting, yet we're surprisingly ignorant about the basic properties of the lightbulb, let alone the recent innovations in energy-saving lighting design that can cut consumer costs 30 to 60 percent a year. Quick, how many lumens in a 100-watt bulb? If you answered 1,750, you're among the lighting elite.
Some vital terminology: Lumens are a measure of light output. The watt is a measure of electric power dissipated or consumed. Footcandles are measurements of light distribution on a horizontal surface. According to the Illuminating Engineering Society, a measure of 30 to 50 footcandles is adequate for most home or office work, allowing comfortable illumination without eye strain. For close work — sewing, reading fine print — you may need 200 to 500 footcandles.
