Long Lifetime

Long lifetime

Kyocera LED lamp structure

Kyocera's LED is mounted in a ceramic package and unlike plastic packages, ceramic shows little deterioration from heat and light.  As a result, the LED lifetime is extended significantly.  Shown below, the Kyocera LED lamp retains 95% of its initial luminous flux after 98,400 hours of continuous testing. Correlated Colour Temperature (CCT) also remains stable after the same time period.

Current test of Kyocera LED lamps

Higher than 95% of initial luminous flux has been maintained after 98,400 hours

Correlated colour temperature (CCT) remains stable even after 98,400 hours

  • Current test conditions: ambient temperature of 25°C, LED chip surface temperature of 75°C
  • Current test of LED lamps does not assure lifetime of luminaires
  • All test data herein was measured by Kyocera
