BSR/IES LM-80-2017 (R202x), Approved Method: Measuring Luminous Flux and Color Maintenance of LED Packages, Arrays and Modules
LEDs typically exhibit very long operational life characteristics and, depending on drive current and use conditions, can be in use for 50,000 hours or longer. The light output from LEDs slowly decreases over time. This characteristic of declining output without catastrophic failure creates a risk that an LED-based lighting product near end-of-life may be operating, but performing outside the product’s specification, or outside required codes, standard practices, or regulations. LEDs may also undergo gradual shifts in the emitted spectra over time that may result in unacceptable appearance, color rendering, or degraded efficacy.

BSR/IES LM-20-202x, Approved Method: Photometry of Reflector Type Lamps
As used in this laboratory method, a reflector-type lamp is a lamp having a reflective element(s) intended to redirect flux from the emitting element (e.g., filament, arc) to form the intended spatial distribution of the light. For example, a reflective element might take the form of a reflective coating applied to the lamp bulb, or a reflector positioned relative to the emitting element and permanently affixed in this position. This laboratory method does not apply to the following: lamps of standard bulb shape to which an integral reflector is added such as silver-bowl and silvered-neck lamps; reflector-type lamps that are designed for special applications, such as automotive headlamps and projection lamps, for which lamp specific test procedures have been established; or lamps that are known to have special testing requirements beyond those addressed in this laboratory method such as linear fluorescent reflector lamps that have special temperature or orientation requirements.

BSR/IES RP-37-202x, Recommended Practice: Lighting Airport Outdoor Environments
This Recommended Practice (RP) has been prepared as a guide for the application of fixed outdoor lighting in and around the airport environment with respect to the airport’s special requirements. These requirements include (but are not limited to): Height restrictions (such as obstructions affecting navigable airspace) as defined by the governing civil aviation authorities; The ability to distinguish color of light for visual cues; Prevention of light trespass that may interfere with the vision of pilots or air traffic control tower (ATCT) personnel; Air traffic controllers’ ability to see approaching aircraft and aircraft performing ground operations within the “aircraft movement area” without glare or direct or indirect light trespass; and Pilots’ ability to detect runway lighting without glare or direct or indirect light trespass.

BSR/IES LM-85-202x, Approved Method: Optical and Electrical Measurements of LED Packages and LED Arrays
Packages and LED Arrays (new standard) To update and improve the IES document based on new knowledge, post-publishing practice, and users’ inputs, providing practical measurement procedures.

BSR/IES/NALMCO RP-36-202x, Recommended Practice: Lighting Maintenance
How a lighting system will be maintained is important information for lighting designers, just as design information is important for maintenance personnel. Since the maintenance method influences the extent of expected light loss, it also relates to the amount of lumen output needed to maintain the required illuminance. In other words, if a well-maintained lighting system will result in a higher maintained illuminance, then fewer lumens are needed to produce the design level, which may translate to fewer and/or lower-wattage luminaires. This will reduce capital and energy costs.

BSR/IES LM-86-202x, Approved Method: Measuring Luminous Flux and Color Maintenance of Remote Phosphor Components
This Lighting Measurement (LM) document addresses the test method for measuring degradation behavior of the remote phosphor component. In addition to using the method of testing an entire remote-phosphor LED lamp or luminaire per IES LM-84 -14, IES Approved Method for Measuring Luminous Flux and Color Maintenance of LED Lamps, Light Engines, and Luminaires, this LM provides an alternative method, whereby the separable remote phosphor component can be tested.

BSR/IES LM-62-202x, Approved Method: Guide for Laboratory or Field Measurements of Fluorescent Lamps and Ballasts in Luminaires
This Approved Method covers only thermal measurement of fluorescent lamps and ballasts in luminaires. Its purpose is to aid luminaire designers in achieving optimum performance of these components in given applications. In addition to the general test procedures outlined in this document, lamp and ballast manufacturers’ data sheets should always be consulted when possible. Manufacturers of these products often have technical guides available, detailing product-specific thermal test point locations and limits. Manufacturers should be contacted for these guides for the products used in the design.

BSR/IES LM-65-202x, Approved Method: Life Testing of Single-Based Fluorescent Lamps
The fluorescent lamp is an electric discharge source in which light is produced predominantly by fluorescent powders activated by ultraviolet energy generated by mercury atoms brought to an excited state by collision with electrons in a low-pressure rare-gas mercury discharge or arc. There are two main ways to generate the electrical discharge. The most common is to pass a current through the gas via electrodes (cathodes) that are connected by wires through the glass envelope. The other way is to induce a current without the need of electrodes by use of high-frequency magnetic induction. This type of discharge source is commonly called an electrodeless discharge lamp.

BSR/IES LM-81-202x, Approved Method: Photometric Testing of Skylights and Tubular Daylighting Devices under Hemispherical Sky Conditions
This Lighting Measurement (LM) document provides the IES recommended uniform method for determining and reporting the photometric characteristics of skylights and tubular daylighting devices that incorporate a means to diffuse the natural hemispherical daylight as the daylight passes through the daylighting system. It describes the procedures followed and the precautions observed in obtaining uniform and reproducible measurements of tubular daylighting devices and skylights with glass or plastic glazing. This document identifies the components and the structure type needed to adequately measure daylighting devices. The procedures, calibration of the equipment, and determination of sun angles and sky conditions are also discussed. This method is not recommended for daylight devices with clear glazing.

BSR/IES LM-37-202x, Approved Method: IES Guide for Determination of Average Luminance (Calculated) for Indoor Luminaires
The concept and limitations of average luminance is addressed in this document. Although simple projected area examples are presented and more detailed area calculation methods are developed for reference purposes in Annex A, it remains the user’s responsibility to seek out the most appropriate methods or formulas each time he or she determines the actual projected areas for a specific luminaire.
