BSR/IES LP-8-202x, Lighting Practice: The Commissioning Process Applied to Lighting and Control Systems
This Lighting Practice (LP) document, developed by the Illuminating Engineering Society describes the technical requirements for commissioning lighting and control systems to achieve owner performance criteria in new construction. Retro-commissioning, or application of the Commissioning Process to an existing facility that has not previously been commissioned, is not specifically addressed in this document, although the same basic process can be applied. Project need: The lighting design intent should be monitored throughout the entire construction process, particularly in the final installation. The correct luminaires, lamps, ballasts, and controls should be properly installed and perform according to criteria that achieve user acceptance and satisfy the owner’s operational needs. Stakeholders: Lighting practitioners, manufacturers, contractors, building owners/managers, code officials, the general public.

BSR/IES LS-4-202x, Lighting Science: Measurement of LIght: The Science of Photometry
This Lighting Science (LS) document describes the various types of photometry and photometric instrumentation, including laboratory and field equipment and measurement types, and instructions for some types of field measurements. However, it does not provide instructions or methodology for performing laboratory tests. For that kind of information, the reader is referred to the IES Lighting Measurement (LM) series of documents.

BSR/IES LM-41-202x, Approved Method: Photometric Testing of Indoor Fluorescent Luminaires
This guide is intended to provide uniform guidance useful for evaluating the performance of fluorescent luminaires for general lighting. Luminaire characteristics are to be reported in terms of intensity distribution, flux distribution and efficiency. These performance data may be developed into factors and/or tables that allow the predetermination of illuminance and luminance for any conventional plane or boundary surface.

BSR/IES LM-48-202x, Approved Method: Testing the Calibration of Locking-Type Photoelectric Control Devices Used in Outdoor Applications
The objective of this Approved Method is to describe a procedure and test equipment by which photoelectric control devices can be tested to obtain accurate, optimally comparable data. The system aspects that need to be understood to calibrate light sensitive control devices used in roadway and outdoor area lighting are covered. Although photo controls are often used in indoor applications, the method of testing the calibration described in this Approved Method is limited to photo controls used in outdoor applications.

BSR/IES LM-66-202x, Approved Method: Electrical and Photometric Measurements of Single-Based Fluorescent Lamps
This Approved Method describes the procedures to be followed and the precautions to be observed in order to obtain uniform and reproducible measurements of the electrical and photometric characteristics of both integrated and non-integrated single-based compact fluorescent lamps, and integrated electrodeless lamps, under standard conditions in alternating current (AC) circuits (both line- and high-frequency).

BSR/IES RP-2-202x, Recommended Practice: Lighting Retail Spaces
This Recommended Practice was written for designers with varying levels of experience in retail lighting design. The study of this Recommended Practice, including the references and annexes found at the back, should serve as a foundation for good retail and merchandise lighting. For optimum success in lighting retail spaces (or where specialized merchandise lighting is required), the services of a professional specializing in retail merchandise lighting design is recommended. Ideally, this lighting professional should join the design team during the early stages of project development.

BSR/IES RP-3-202x, Recommended Practice: Lighting Educational Facilities
This Recommended Practice was developed to enable architects, engineers, lighting designers, and other lighting decision makers to ensure that their lighting criteria are consistent with good current practice; to assist school and university staff in understanding the importance of the role that lighting plays in educational environments; and to facilitate conversations about lighting between school and university staff, architects, engineers, lighting designers and other designers. It addresses all levels of education, from preschool to university facilities.

BSR/IES RP-10-202x, Recommended Practice: Lighting Common Applications
This Recommended Practice primarily addresses design considerations and illuminance criteria for common areas, which should influence luminaire optical selections, light source choices, and final layouts. It is important that deliberate thought be given to details beyond the recommended illuminances in this chapter. For example, in Section 3.6 Food Service, the vertical illuminance citation does not necessarily demand a uniform array of low-wattage wall washers. Such lighting can be achieved with uplight or downlight in each shelf, a perimeter slot-like detail along the back bar elevation, adjustable accents, the smallest of daylight-slots in the top of the back bar (for at least the daytime condition), or some combination of these. Each of these can achieve the target illuminance, but each has a distinctly different appearance and requires different architectural detailing. Such specific details are not enumerated for all tasks. The design team is responsible for determining and addressing indoor and outdoor lighting and energy criteria set forth by authorities having jurisdiction, which may be different from and supersede IES criteria.

BSR/IES RP-11-202x, Lighting for Interior and Exterior Residential Environments
This Recommended Practice is a guide for designing and for teaching lighting. It covers residential living spaces and other areas intended to impart a residential atmosphere. It describes design objectives, criteria for quantity and quality of illuminance, lighting methods, types and uses of equipment, energy use, and electrical code considerations. Various solutions that address residential lighting problems are also presented.

BSR/IES RP-16-17 Addendum 4-202x, Nomenclature and Definitions for Illuminating Engineering
Includes Changes and deletions to lighting definitions in ANSI/IES RP-16-17.

BSR/IES RP-42-202x, Recommended Practice: Dimming and Control Method Designations
This Recommended Practice provides simple standard designations for open non-proprietary dimming and control methods and protocols for luminaires (including standalone lamps) and controllers. This document does not address the internal control techniques within a luminaire, although the designations may be applicable. Inclusion of dimming methods and control protocol designations in design and construction documents—especially luminaire and control schedules—provides clarity in selection of compatible dimming and control equipment. Manufacturers of luminaires, drivers, controllers, and lamps are encouraged to use these same designations to clearly identify dimming methods that are compatible with their products in data sheets.

BSR/IES LP-7-202x, Lighting Practice: The Lighting Design and Construction Process
IES LP-7-20 covers the essential process that a lighting practitioner follows in concert with members of the building team to document a design for construction.

BSR/IES LP-11-202x, Lighting Practice: Environmental Considerations for Outdoor Lighting
This Lighting Practice (LP) document outlines the environmental considerations of exterior lighting, especially as related to glare, sky glow, light trespass and the impact of electric light at night on flora and fauna. In addition, this LP provides information on how to assign lighting zones, and how to use the Joint IDA-IES Model Lighting Ordinance (MLO) with User’s Guide, as a basis for an exterior lighting ordinance. Finally, this LP discusses community-based design and makes specific recommendations for lighting outdoor areas.

BSR/IES RP-31-202x, Recommended Practice: Economic Analysis of Lighting
This Recommended Practice (RP) will help answer many types of lighting economic questions. It provides a framework for selecting from a group of competing lighting designs. It gives insight into the question of when a system under consideration will “pay off.” It can help the lighting professional make energy conservation decisions. Most importantly, it provides methods for gauging the profitability of a capital investment in a lighting system, which can be objectively compared to other competing capital investments. This RP begins with a discussion of the second-level methods, concentrating on LCCBA. This is followed by sections on sensitivity analysis and benefit analysis. Finally, because the lighting practitioner is likely to encounter the first-level methods in practice, these are also covered. In discussing the first-level methods, emphasis is placed on their shortcomings so that the lighting professional can understand why their use is not encouraged.

BSR/IES LS-3-20 Lighting Science: Physics and Optics of Radiant Power
This document describes the physics of radiant energy for various light source types, as well as the physical optics used for manipulating light.

BSR/IES LS-6-20 Lighting Science: Calculation of Light and Its Effects
The purpose of this Lighting Science document is to provide the theoretical basis for lighting calculations, to describe how this theory is approximated and used, and to describe how it is embodied in most lighting analysis software. This can provide, from a user’s perspective, an understanding of the power and limitations of calculations—however performed—and thus make clear their use in the lighting design process.

BSR/IES LS-8-20 Lighting Science: Vision – Perceptions and Performance
This document provides an overview of visual perceptions and performance, covering topics such as brightness, glare, flicker, visibility, and illuminance criteria. It introduces scientific literature and past research results but does not serve as a complete literature review on any specific topic. The document provides basic descriptions and background of visual phenomena in order to guide lighting practitioners. For some topics, established formulas and processes are reviewed, but specific criteria or other recommendations are not provided. This document begins with a review of psychophysics, which is the primary method of study for perception and performance, in order to help readers understand the strength and limitations of the provided material.

BSR/IES RP-27-20 Recommended Practice: Photobiological Safety for Lighting Systems
This Recommended Practice covers the classification, labeling and informational requirements for lamps that emit optical radiation in the wavelength range from 200 nm to 3000 nm, with exception for LEDs used in optical fiber communication systems and for lasers. Lamps included are incandescent filament lamps including tungsten halogen types and incandescent heating sources, low pressure discharge lamps, high intensity discharge (HID) lamps, short arc lamps, carbon arcs, electroluminescent lamps, LEDs, organic LEDs (OLEDs), and laser-driven broadband sources. For the purposes of this document, induction lighting is classified under fluorescent lamps and plasma lighting is classified under HID lamps. Federal mandatory requirements for lamps subject to specific Federal Regulations take precedence over requirements included in this consensus standard.
This Recommended Practice combines and updates the material from the previous ANSI/IES RP-27 series:

  • ANSI/IES RP-27.1-15, Recommended Practice for Photobiological Safety for Lamps and Lamp Systems – General Requirements
  • ANSI/IES RP-27.2-00(R17), Recommended Practice for Photobiological Safety for Lamps and Lamp Systems – Measurement Techniques
  • ANSI/IES RP-27.3-17, Recommended Practice for Photobiological Safety for Lamps and Lamp Systems – Risk Group Classification and Labeling

BSR/IES LM-61-20 Approved Method: Identifying Operating Factors for Installed High Intensity Discharge Luminaires
This LM outlines factors that can cause differences between calculated and measured illuminance and luminance values of outdoor high intensity discharge (HID) and low pressure sodium (LPS) lamps and luminaires. It does not offer solutions, nor does it quantify all of the possible variables that might be encountered. The relevant ANSI/IES Recommended Practice document should be consulted for specific design recommendations.

BSR/IES LM-72-20 Approved Method: Directional Positioning of Photometric Data
It is important to note that this document assigns specific, standard meaning to certain words; thus, some users might need to adjust their vocabulary. Most should find a positioning system compatible with their normal patterns and experience. This document does not show a preference for any system, but rather describes each of the three systems and then explains how to convert between them. In applying CN or CCE, four types of angular “rotation” are defined (Orient, Tilt, Roll, and Spin), and each shall be preformed in the defined order. Any or all of the rotation angles may be zero. Each subsequent rotation is applied to the axis system as previously rotated (the local axes), not the original axis system (the global axes). Orientation, Tilt, Roll, and Spin can be described using X, Y, and Z axes, but the CN system and CCE system are described separately, and separate drawings of the coordinate system are needed.

BSR/IES TM-26-20 Technical Memorandum: Projecting Catastrophic Failure Rate of LED Packages
This document describes three methodologies for projecting the catastrophic failure rate of LED packages. This document applies to the LED packages that are defined in ANSI/IES RP-16-17, Nomenclature and Definitions for Illuminating Engineering (see Section 2.1). The three methodologies presented are for information only and do not represent a complete set of methodologies in existence; these represent the methodologies that are publicly available, and have been made available, for publication by the IES. The IES does not endorse any of these specific methods, and it is not the intent of this TM to use any of these methods for incorporation into any standards publication.

BSR/IES TM-28-20 Technical Memorandum: Projecting Long-Term Luminous Flux Maintenance of LED Lamps and Luminaires
This document recommends the methods for projecting long-term luminous flux maintenance of LED lamps and luminaires using data obtained when testing them per IES LM-84-14, Approved Method for Measuring Lumen and Color Maintenance of LED Lamps, Light Engines, and Luminaires, as well as data when testing LED sources per IES LM-80-08, Approved Method for Measuring Lumen and Color Maintenance of LED Light Sources.
