BSR/IES RP-4-20 Recommended Practice: Library Lighting
Today’s library is different in many ways from libraries of the past. Newer lighting techniques and lighting equipment provide the designer with the tools to meet the needs of the varied visual tasks encountered in today’s libraries. This document has been written for use by lighting design professionals, architects, engineers, library administrators, librarians, and educators to provide useful practical information that will help produce an energy efficient, pleasing lighted environment.
BSR/IES TM-15-20 Approved Method: Luminaire Classification System for Outdoor Luminaires
This Technical Memorandum defines a lighting application classification system for outdoor luminaires that provides information to lighting professionals regarding the lumen distribution within solid angles of specific interest. The lumens within these solid angles are intended to be one of the metrics used to evaluate luminaire optical distribution including the potential for light pollution and obtrusive light, but not as the only metric that should be evaluated.

BSR/IES LS-5-20 Lighting Science: Color
This document covers the basics of color science, including color vision fundamentals and an overview of colorimetry. It also describes color terminology, color properties of light sources, and the use of color in applied lighting, which includes discussions of common color metrics. This document is not meant as a substitute for more comprehensive literature on this topic or for the standards that are referenced within; instead, it is meant to provide general knowledge to a lighting practitioner and direct readers to appropriate material. It focuses on practical use, rather than acting as a historical record.
BSR/IES TM-24-20 Lighting Science: An Optional Method for Adjusting the Recommended Illuminance for Visually Demanding Tasks within IES Illuminance Categories P through Y Based on Light Source Spectrum
This TM describes how a light source’s SPD affects pupil size, visual acuity, and visual efficiency under interior lighting conditions, and establishes an optional calculation method, Equivalent Visual Efficiency (EVE), for adjusting IES recommenced illuminance targets under limited circumstances when visual tasks require the ability to discern achromatic visual detail to ensure speed and/or accuracy in the performance of the visual task.

BSR/IES LP-3-20 Lighting Practice: Designing and Specifying Daylighting for Buildings
This document provides detailed discussions and guidelines on the design and performance of these systems. The contents of this document are of value to architects, electrical and mechanical engineers, interior designers, landscape architects, contractors, equipment and material manufacturers, as well as end users such as developers, building owners, and facility managers. Each of these individuals plays a role in defining how a daylight system will perform over its lifetime.
