IES LM-10-20 (R2023)

This document defines adequate and uniform methods for measuring and reporting the photometric characteristics of roadway and area lighting fluorescent luminaires. It describes characteristics of these luminaires and some components, as well as the requirements for the thermal environment and proper control of the electrical and mechanical systems involved. General test conditions and the testing procedure best suited for achieving accurate and consistent photometric results are defined. The test procedures for luminaires using fluorescent lamps described herein can utilize either absolute or relative photometry methods.
