Caption

Energy Star logo on the compact fluorescent light (CFL) bulb package. Compared to incandescent light bulbs, CFLs are generally several times more efficient and have a longer life. Despite the improved efficiency, the actual environmental effect of CFLs is the subject of much debate. CFLs typically use mercury vapour and need to be properly disposed. A product must meet certain energy efficiency requirements set forth by the US Environmental Protection Agency (EPA) in order to earn the Energy Star symbol.
