Fluorescent lamp

A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than incandescent lamps. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output.

Fluorescent lamp fixtures are more costly than incandescent lamps because they require a ballast to regulate the current through the lamp, but the lower energy cost typically offsets the higher initial cost. Compact fluorescent lamps are now available in the same popular sizes as incandescents and are used as an energy-saving alternative in homes.

Because they contain mercury, many fluorescent lamps are classified as hazardous waste. The United States Environmental Protection Agency recommends that fluorescent lamps be segregated from general waste for recycling or safe disposal.

Salman the Persian

Salman the Persian or Salman al-Farsi (Arabic: سلمان الفارسي‎), born Ruzbeh (Persian: روزبه‎‎), was a companion of the Islamic prophet Muhammad and the first Persian who converted to Islam. During some of his later meetings with the other Sahabah, he was referred to as Abu Abdullah ("Father of Abdullah"). He is credited with the suggestion of digging a trench around Medina when it was attacked by Mecca in the Battle of the Trench. He was raised as a Zoroastrian, then attracted to Christianity, and then converted to Islam after meeting Muhammad in the city of Yathrib, which later became Medina. According to some traditions, he was appointed as the governor of Al-Mada'in in Iraq. According to popular Shia tradition, Muhammad considered Salman as part of his household (Ahl al-Bayt). He was a renowned follower of Ali ibn Abi Talib after the death of Muhammad.

Birth and early life

Salman was a Persian born either in the city of Kazerun in Fars Province, or Isfahan in Isfahan Province, Persia. In a hadith, Salman also traced his ancestry to Ramhormoz. The first sixteen years of his life were devoted to studying to become a Zoroastrian magus or priest after which he became the guardian of a fire temple, which was a well-respected job. Three years later in 587 he met a Nestorian Christian group and was so impressed by them. Against the wishes of his father, he left his family to join them. His family imprisoned him afterwards to prevent him but he escaped.
