This document is intended to be a supplement to the IES RP-6-15, Recommended Practice for Sports and Recreational Area Lighting. RP-6-15 covers design and application information critical to sports lighting that is not contained in this document. This document should not be used as a replacement for RP-6-15. This document presents light sources that are relatively new to the lighting industry and are currently being used or considered for use in sports and recreational lighting applications. Where appropriate, the new sources will be compared and contrasted with traditional sources. This document is meant to focus on mainly recreational sports lighting, encompassing the same breadth of projects as noted in RP-6-15. The lighting requirements for professional sports and the related broadcasting issues are not addressed in this document.

It is intended that this information or an update of this information will be included in the next version of RP-6. However at this time it is felt that these new sources are significantly different from traditional sources that a separate document clarifying the differences and their impact should be issued.

It is important to note that in some applications—such as retail and museum lighting—a characterization of anticipated chromaticity shift of SSL products over their usable lifetime is very important to the user. Further, the chromaticity coordinates of some light sources can change significantly from their initial values over time. This document provides recommendations for projecting long-term chromaticity coordinate stability of LED light sources using data obtained per ANSI/IES LM-80-15, Approved Method: Measuring Luminous Flux and Color Maintenance of LED Packages, Arrays, and Modules.

This Technical Memorandum (TM) provides a recommended standardization of parameters attached to objects, object libraries, or parametric features that represent luminaires for use in many different types of BIM software. This TM does not include recommendations or explicit prescriptions for geometric representation.

This Technical Memorandum establishes consistent methods for:

• Specification of criteria
• Precision of calculations
• Comparisons of calculations to criteria

Uncertainty is inherent in every measurement. To truly understand the value of a measurement, the uncertainty of such should be analyzed. A critical step of this analysis is to know the uncertainty contributed by the instruments used to make the measurement. The intent of this document is to provide a common approach to the uncertainty analysis for calibration of lumen measuring equipment (integrating spheres) with standard incandescent lamps, including tungsten-halogen, that have been assigned values of total luminous flux and/or total spectral radiant flux. This document provides a detailed and step-by- step method for determining uncertainty of certain calibration procedures common to instruments used in lumen measurement laboratories. It uses the structure proposed in the Guide to the Expression of Uncertainty in Measurement (GUM) for its recommendations. For each calibration procedure presented in this document, a mathematical model is developed, estimates of each input quantity are discussed, and guidance is provided for the evaluation of the standard uncertainty of each input estimate. With this information, the combined standard uncertainty is calculated, effective degrees of freedom are calculated, and finally, the expanded uncertainty is reported.

This evaluation method is applicable to light sources and lighting systems intended for general illumination of indoor spaces and some outdoor settings, at light levels where photopic vision is dominant. It is best suited to characterize nominally white light sources (i.e., those that fall on or near the Planckian locus).

This Technical Memorandum describes a method for evaluating light source color rendition that takes an objective and statistical approach, quantifying the fidelity (closeness to a reference) and gamut (increase or decrease in chroma) of a light source. Importantly, it does not attempt to evaluate human color preference or provide a single number that captures the combined color rendition qualities. However, using the two-dimensional characterization
provided by the Fidelity Index (R_f) and Gamut Index (R_g), a user is expected to be able to rely on experience and/or design guidelines to determine what is most appropriate for the specific application in consideration. The method also generates a color vector graphic that indicates average hue and chroma shifts, and which helps with interpreting the values of R_f and R_g.

While this document relates to a previous version of ANSI/IESNA RP-8-83 (reaffirmed in 1993), the valuable information on a luminaire light distribution classification system is still valid in helping the designer narrow down the choice of luminaires for a given roadway lighting project. The discussion centers on the various factors which lighting designers (for new installations) and maintenance managers (for replacement luminaires) should consider when specifying roadway luminaires. This TM does NOT present a new luminaire light distribution classification system.

This document provides guidance and recommended procedures for sampling, test intervals and duration, and a method for long-term luminous flux maintenance projection for LED lamps and luminaires. The intent is to help product manufacturers and users, standards developing bodies, and other organizations to avoid any unnecessary burdens related to excessive product testing. A balance was sought between testing time and effort on one side, and sufficient statistical rigor on the other. A direct and a combined method for luminous flux maintenance projection are proposed; the latter allows the use of luminous flux maintenance data obtained for both the lamp or luminaire being tested as well as the LED sources used in it.

The architectural lighting community has long relied on standardized file formats for the electronic transfer of photometric data and related information. There is, however, also a need to distribute spectral data. Such data is pertinent, but not limited to, the spectral radiant flux of lamps and other light sources, the spectral transmittance of color filters, and the spectral reflectance of paint and other finishes. This data may be obtained when testing a light source, luminaire or material and may then be used in lighting application software, rendering software, analysis software or optical design software.

Generally the document will contain a single spectral power distribution. The data is formatted in accordance with W3C Extensible Markup Language (XML) 1.1 Recommendation and the W3C XML Schema Definition Language (XSD). This allows end users to utilize and view the data directly without the need for proprietary software.
