Generally, the replacement of housing luminaires is recommended when they have become 10 to 20 years old. On the supposition that a household has 10 luminaires on average, the number of luminaires in need of replacement is estimated at more than 100 million. Since luminaires are regarded as durables, most more than 10 year-old luminaires are not replaced as long as they can be lit somehow. It is necessary to establish a clear standard on the service life of luminaires, and thereby make general consumers more conscious of the need to replace them.
