1. Ordinary incandescent lamp: used in living room, living room, lobby, guest room, shop, restaurant, walkway, conference room and courtyard. It is characterized by good color rendering, instant lighting when the light is turned on, continuous dimming, simple structure and low price, but short service life and low light efficiency.

2. Halogen tungsten lamp: used for special lighting of conference rooms, exhibition halls, living rooms, commercial lighting, film and television stages, instruments, automobiles, airplanes and so on. Its characteristics are that the light efficiency and service life are more than doubled than those of ordinary incandescent lamps, and its volume is small.

3. Fluorescent lamp: Fluorescent lamp is a widely used energy-saving lighting source, including straight tube type, ring type and compact type. Its characteristics are high light efficiency, long service life and good light color.

4. Low-pressure sodium lamp: used for lighting in tunnels, ports, docks, mines, etc. Its characteristics are high luminous efficiency, long service life, high luminous flux maintenance rate, strong fog permeability, but poor color rendering. ?
