BSR/IES LP-1, Lighting Practice: Designing Quality Lighting for People and Buildings
Open for Public Comments June 14 – July 29, 2019
Light + Design was developed to introduce architects, lighting designers, design engineers, interior designers and other lighting professionals to the principles of quality lighting design. These principles, related to visual performance, energy and economics, and aesthetics, can be applied to a wide range of interior and exterior spaces to aid designers in providing high-quality lighting to their projects.
BSR/IES TM-21, Projecting Long-Term Lumen, Photon, and Radiant Flux Maintenance of LED Light Sources
Open for Public Comments June 14 – July 29, 2019
One of the benefits that LED light sources can provide is very long usable life. Unlike other lighting technologies, LEDs typically do not fail catastrophically1 during use. However, over time the light output will gradually depreciate. At some point in time the light emitted from an LED depreciates to a level where it is no longer considered adequate for a specific application. It is important in lighting design to understand when this “useful lifetime” of an LED source is reached.
BSR/IES LM-75, Approved Method: Goniometer Measurements and Types, and Photometric Coordinate Systems
Open for Public Comments June 14 – July 29, 2019
This document provides definitions of goniophotometer types, spherical coordinate systems, and a general guide to goniophotometer calibration. Definitions presented herein are generally consistent with those in corresponding CIE publications [CIE 102i and CIE 121ii]. Differences or inconsistencies are noted.
BSR/IES LM-40, Approved Method: Life Testing of Fluorescent Lamps
Open for Public Comments June 14 – July 14, 2019
This guide describes the procedures by which fluorescent lamps can be operated under controlled, conditions to obtain optimally comparable data on individual lamp life, changes in light output, and other parameters that vary during the life of the lamp.
