IES LM-41-20 PDF Download

The IES LM-41-20 standard is a comprehensive guide that outlines the procedures for evaluating and reporting the photometric characteristics of indoor fluorescent luminaires. It offers a systematic approach to testing the luminaires and their components, ensuring consistency and accuracy in the results obtained.

The standard covers various aspects of the testing process, including the specifications for the thermal environment, as well as the requirements for controlling the electrical and mechanical systems during testing. By addressing these factors, the standard aims to create standardized conditions that can be replicated across different testing facilities, resulting in reliable and comparable photometric measurements.

Moreover, the document emphasizes the need for proper test conditions and outlines the recommended testing procedure to be followed. This includes guidelines for sample preparation, measurement setup, and data collection, all of which contribute to the overall accuracy and reliability of the photometric results.
