The fluorescent lamp initially developed in 1938, mainly adopted for the military purpose during the World War II and widely disseminated to the public after the War.
The fluorescent lamp is 7~8 times bright in brightness and lasts 10 times long in the operating life as compared with incandescent lamp. The light beam is so tender and hardly accompanies heat and
moreover, consumes much less power than incandescent lamp. Good color rendering is one of its strong points and you can have your own color choice at your option.
