IES Approves Four Standards

 

Here are four recently approved IES standards:

 ANSI/IES TM-39-25 Technical Memorandum: Quantification and Specification of Flicker 
This Technical Memorandum (TM) catalogs currently documented metrics and specification criteria related to the human perception of periodic TLM and summarizes existing research. It identifies a path toward an IES standard method for quantifying and specifying flicker for architectural lighting general illumination. Coming soon to the IES Lighting Library.

ANSI/IES RP-8-25 Recommended Practice: Lighting Roadway and Parking Facilities 

This Recommended Practice is a compilation of lighting design techniques and criteria, all offered for quality roadway lighting solutions. Coming soon to the IES Lighting Library.

ANSI/IES LM-79-24 Approved Method: Electrical and Photometric Measurements of Solid State Lighting Products
LM-79 is one of the most important test procedures for LED lighting products. It defines the procedures to be followed and precautions to be observed in performing reproducible accurate measurements of total luminous, radiant, or photon flux; electrical power; system efficacy; luminous, radiant, or photon intensity distribution; and color quantities and/or spectrum of solid-state lighting (SSL) products for illumination purposes, under standard conditions.

Changes have been made in this new edition to replace Annex A – Airflow Considerations for Testing SSL Products, Annex C – Power Supply Resistance and Inductance Dependency, plus changes for spectral testing, an updated test report outline.

ANSI/IES TM-41-24 Technical Memorandum: Standard Format for the Electronic Data Transfer of Light Output Maintenance Characteristics of Solid-State Light Sources

This NEW Technical Memorandum (TM) describes the storage and transfer file format for LM-80 maintenance test data for solid-state light sources, such as LED packages, arrays, and modules; or laser diode packages, arrays, and modules. This document provides a standard format for the electronic transfer of LM-80 test data in XML format. All required LM-80 report data items are included, as well as optional data items such as the spectral power distribution (SPD).

It is available for purchase here.
