For safety, energy conservation and the global environment, please inspect and replace lighting fixtures that are near the end of their service life as soon as possible.* ambient temperature 30 ℃ or less, 10 hours / day, annual 3,000 hours lighting(If the ambient temperature is higher or the lighting time is longer, the replacement timing and service life will be shortened.)According to the explanation of JIS C 8105-1: 2010.Cumulative lighting time (h)Relationship graph between LED temperature and service life40,000Comparison data of luminous flux maintenance rate100908070603,0005,000Operation timeMain applicationsTemperature (°C)Replacement time (years)60,00020,0007080100V dichroic halogen lamp（rated service life of 100Vdichrogen lamp）Compact fluorescent lamp* If used under the following conditions, the temperature rise of the insulating material will increase and the fixture life will be shortened.Lighting fixtures have adequate time for replacement.Adequate replacement guideline of lighting fixtures10,00020,00030,00040,000Time（h）VoltageService life lineENDO LED temperature setting90110100120LED temperature（℃）130140Ceramic metal halide lamp15030 or less403.5Service life of LED moduleThe service life of the white LED is defined in "JIS C 8105 - 3"."Total lighting time until the LED module does not turn on, or total lighting time until it falls to 70% of the measured value at the beginning of lighting, whichever is shorter, when the LED module is lit under the conditions specified by the lighting fixture manufacturer" (The "rated service life" of internal light type indicator lights that use LEDs as the light source is the time until the initial luminous flux of the light source is attenuated by 50%) We estimate the service life of the module according to these regulation.Since the service life of the LED module is the design service life, it is not the guaranteed service life. Also, the service life of the LED module and the service life of the lighting fixture are different. Reliability for long service life of 40,000 hoursBy designing our products with a sufficient temperature margin from the normal set value, we ensure high reliability for long service life. This also contributes to improving the reliability of the entire fixture.Luminous flux maintenance rateSet according to "LED modules for general lighting service - Performance requirements (JIS C 8155)".Reliability of luminous flux maintenanceThe LEDZ series maintains brightness from the beginning to the end and shows a higher luminous flux maintenance rate than conven-tional lamps.The replacement guideline of lighting fixtures is about 10 years, internal deterioration progresses.Cumulative failure rate of lighting fixturesCumulative lighting years(10 hours / day, annual 3,000 hours lighting) (year)Color shift of LEDsIn comparison with general light sources (fluorescent lamps or incandescent bulbs etc.), color shift of white LEDs is large, in fact.For this reason, please note that colors may vary depending on each LED lighting fixture.
