December 30, 2014 - TM-21 Calculators

The ENERGY STAR TM-21 Calculators below are used to support lumen maintenance requirements, and have been updated to reflect the recently published TM-21-11 Addendum A. The majority of products should use the standard TM-21 Calculator, and products that utilize LEDs with uneven LM-80-08 lumen maintenance test intervals can use the TM-21 Calculator for Uneven Test Intervals.
