    Product Detailed Description

      

    The purpose of LM-80-08 is to allow a reliable comparison of test results among laboratories by establishing uniform test methods.  It addresses the measurement of lumen maintenance testing for LED light sources including LED packages, arrays and modules only. It does not provide guidance or recommendations regarding prediction estimations or extrapolations for lumen maintenance beyond the limits of the lumen maintenances determined from actual measurements.

    Contents: Definitions/Ambient Physical Conditions/Electrical and Thermal Conditions/Test and Measurement Procedures/Lumen Maintenance Testing Method for LED Sight Sources/Test Report

    Also of interest: LM-79-08 Approved Method: Photometric Measurements of Solid State Lighting Products
