The fluorescent luminaires in classrooms have been replaced with LED ones in accordance with the "Regulations to promote the rationalization of energy use in public institutions". In schools, the existing fluorescent luminaires work well with new lamps and ballasts made by different manufactures and they fail to work, the only faulty parts are needed to be replaced. However, a faulty LED luminaire have to be replaced with a whole new one. Thus, users hope that the maintenance of LED luminaires is as economical and easy as that of fluorescent luminaires. In this study the usages of existing fluorescent luminaires were investigated and the economic efficiency of the LED luminaires was analyzed with LCC method using the surveyed data. The economic effect of replacing the existing flourescent luminaires with LED ones depends on not only the duration of luminaire usage but also the possibility of parts replacement. Thus, replacement of only faulty parts is required to secure better economic efficiency for the maintenance of the LED luminaire.
