Abstract: Disclosed is a bundle type fluorescent lamp adaptable for the lower temperature atmosphere, in which at least two fluorescent lamps are aligned in a row in the form of a bundle and are accommodated in a transparent or a semitransparent insulative cover, so that the bundle type fluorescent lamp represents superior operational characteristics even if it is installed in a freezing chamber or a cold storage warehouse. Each of the fluorescent lamps includes a glass tube filled with discharge gas and an electrode positioned at both side ends of the glass tube, wherein the fluorescent lamps are bound with each other in a form of a bundle and each electrode of the fluorescent lamps is electrically connected to a power source. The fluorescent lamp includes an external electrode fluorescent lamp, a cold cathode fluorescent lamp or a general fluorescent lamp.
