New Standards Released
The IES recently released four new standards. The documents address current challenges facing the lighting industry - navigating near-field photometry, standardizing iterations of lighting controls intent, the importance of UV lighting and promoting a balanced outdoor environment.

Recommended Practice: Lighting Exterior Applications
ANSI/IES RP-43-22
This document provides pedestrian-oriented illumination recommendations for the reassurance, safety, comfort, amenity, and enjoyment of people in outdoor environments. This RP takes a comprehensive approach and makes recommendations based on lighting zone, glare avoidance, spectrum, and other visually influential conditions. Application of these recommendations will ultimately enhance the visual experience for people, while also respecting the environment.
Lighting Practice: Documenting Control Intent Narratives and Sequences of Operations
ANSI/IES LP-16-22
Intended for a variety of users in the lighting community, this document provides guidance on the documentation of Control Intent Narratives and Sequences of Operation. It is not intended to be a design guide, but rather a reference manual of best practices on how the design, once formulated, is included in the project documentation and communicated to the construction and commissioning teams.
Approved Method: Application Distance Radiometry
ANSI/IES LM-91-22
In near-field conditions the use of far-field IES-format photometric files results in substantially incorrect irradiance, illuminance, or photon-flux density values being predicted by lighting layout models constructed for near-field conditions. This problem can be overcome by using distance-specific IES file(s), generated by first collecting data at the working distance(s) of interest obtained from a single luminaire and then converting them to distance-specific IES file(s), following the protocol described in this document.
Approved Method: Optical and Electrical Measurement of Ultraviolet LEDs
ANSI/IES/IUVA LM-92-22
This document is a guide developed for the measurement of ultraviolet (UV) light emitting diodes (LEDs) and describes the procedures to be followed and precautions to be observed in performing measurements of total radiant flux (total radiant power), electrical power, and wavelength characteristics of ultraviolet (UV) light emitting diodes (LEDs).
Recommended Practice: Horticultural Lighting
ANSI/IES RP-45-21
This document describes the differences between architectural and horticultural lighting design, so that lighting professionals will have the necessary information to translate their architectural lighting know-how into horticultural lighting practice.
