LED product life is defined differently from traditional light sources and is the maintained lumens of the product (lumen maintenance), if there are no product failures. Rated life is usually limited to 6 times the actual measured lumen maintenance. Projected or Calculated Life is calculated to project the number of hours when the LEDs will reach 70% of their initial lumens (L70).
