compact fluorescent lamp

noun
variants: or compact fluorescent lightbulb

Definition of compact fluorescent lamp 

: a tightly coiled fluorescent bulb designed to fit into a standard household light fixture While it sounds like a promising idea, it turns out that the long-lasting, swirl-shaped light bulbs known as compact fluorescent lamps are to the nation's energy problem what vegetables are to its obesity epidemic: a near perfect answer, if only Americans could be persuaded to swallow them.— Michael Barbaro, The New York Times, 2 Jan. 2007 For efficiency, compact fluorescent lamps are an admirable replacement for regular light bulbs. But for home lighting they have failed to sparkle. Consumers dislike the “cold” light they give off and their poor lifespan.The Economist, 20 Aug. 2011 abbreviation CFL
