A fluorescent lamp comprises a light-transmitting glass tube having a softening temperature of about 685 degrees centigrade or less, which is formed into a predetermined shape from a straight glass tube heated after a phosphor layer has been coated on its inner surface. The light-transmitting glass tube does not substantially include lead (Pb) but may include: about 2 to about 5 weight % calcium oxide (CaO), and about 1 to about 3 weight % magnesium oxide (MgO). A stem, having an electrode, is arranged at each end of the light-transmitting glass tube. The fluorescent lamp may be used in a lighting fixture.
