WebbDevelopment of a mercury-free fluorescent lamp is very difficult and the only mercury-free fluorescent lamp that exists, as of mid-2003 has an efficacy of about 10 l mW −1, one-tenth the efficacy of the best mercury-based fluorescent lamp (Osram Sylvania LINEX® Linear Excimer Lamp System, Model LINEX A3-10W40). WebbFluorescent lamps and tubes are an energy-efficient alternative to incandescent lamps for the following reasons: Three to four times more energy-efficient. Cost less to use. Reduce greenhouse gas emissions and other pollution from energy production. Last up to ten times longer than standard incandescent light bulbs.
