    IES LM-58: IES Approved Method for Spectroradiometric Measurement Methods for Light Sources
    Edition: 2014
    $54.18
    / user per year

Content Description

This document describes the requirements and recommendations of the instruments and the procedures for spectroradiometric measurements including those of color performance, spectral irradiance, spectral radiance, and spectral total radiant flux, either in relative or in absolute units. The spectral range is from approximately 200 nm to 1700 nm where the characterization of light from lighting sources, visual displays and light emitting diodes, is most commonly done. This document does not provide in depth detail on every subject, but directs the user to references that completely describe the concepts. The light source or device under test shall be operated in accordance with the appropriate IES LM (Lighting Measurement) or ANSI (American National Standards Institute) document pertaining to the device and is not described in this document. Contents Scope Normative references Definitions and Nomenclature Spectroradiometers Detectors Correction Methods Calculations Reporting Requirements

About IES

The Illuminating Engineering Society of North America (IES) is the recognized technical authority on illumination. For over 100 years; its objective has been to communicate information on all aspects of good lighting practice to its members, to the lighting community, and to consumers, through a variety of programs, publications, and services.

IES is a forum for the exchange of ideas and information, and a vehicle for its members' professional development and recognition. Through technical committees, with hundreds of qualified individuals from the lighting and user communities, IES correlates research, investigations, and discussions to guide lighting professionals and lay persons via consensus-based lighting recommendations.

The Society publishes nearly 100 varied technical publications, and works cooperatively with related organizations on a variety of programs and in the production of jointly published documents and standards.

Local IES Sections and many lighting corporations offer formal educational programs on lighting, utilizing material developed by IES. Sections offer programs related to specific applications based on IES standards - seminars on sports and recreational lighting, lighting industrial facilities, roadway lighting, museum lighting, to name a few. Virtually every curriculum devoted to lighting - from beginner to advanced - includes IES educational materials.

IES is almost 8,000 members strong. Its members work with lighting in a variety of capacities - lighting designers, architects, interior designers, government & utility personnel, engineers, contractors, manufacturers, distributors, researchers and educators - throughout the United States, Canada, Mexico - and around the world. They share a common interest in lighting, and a common desire to promote the use of the latest, most innovative lighting technologies, with a focus on judicious use of energy in all lighting applications
