IESNA: Illuminating Engineering Society of North America

IESNA, the Illuminating Engineering Society of North America, is a nonprofit organization that develops and publishes standards regarding lighting. Headquartered in New York City, United States, IESNA standards are in effect throughout all of North America with its nearly 8,000 members. Internationally, IESNA collaborates with the International Commission on Illumination to promote uniformity with the rest of the world. Standards from IESNA are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: StandardsSubscriptions@ansi.org or 1-212-642-4980 or Request Proposal Price.

Below are IESNA's best-selling standards. To find additional standards, please use the search bar above.

ANSI/IESNA RP-8-14

Roadway Lighting

The primary purpose of this Standard Practice is to serve as the basis for design of fixed lighting for roadways, streets, adjacent bikeways, and pedestrian ways. The Standard Practice deals entirely with lighting design and does not give advice on construction. Its primary purpose is to provide recommended practices for designing new continuous lighting systems for roadways and streets.


ANSI/IES RP-7-17

Recommended Practice for Lighting Industrial Facilities

The primary purpose of this standard is to serve as a guide and educational tool for the design of permanently installed lighting systems for industrial facilities.


ANSI/IESNA RP-27.3-07

Recommended Practice for Photobiological Safety for Lamps - Risk Group Classific

This standard covers the classification, labeling and informational requirements for lamps that emit optical radiation in the wavelength range from 200 nm to 3000 nm except for light emitting diodes used in optical fiber communication systems and for lasers which are covered in a separate series of ANSI standards (Series Z136). Federal mandatory requirements for lamps subject to specific Federal Regulations take precedence over requirements included in this consensus standard.
Note 1: Units of wavelength in this document are exclusively in nanometers (nm).
Note 2: Subtended angles are denoted by the full included angle, not the half angle.


ANSI/IES RP-27.1-15

Recommended Practice for Photobiological Safety for Lamps and Lamp Systems - General Requirements

This Recommended Practice covers the evaluation and control of optical radiation hazards from all electrically powered sources of optical radiation that emit in the wavelength range from 200 nm through 3,000 nm (3.0 um [micrometers]) except for light emitting diodes (LEDs) used in optical fiber communication systems and for lasers which are covered in a separate series of ANSI (American National Standards Institute) standards (Series Z136). Federal mandatory requirements for lamps subject to specific Federal Regulations take precedence over requirements in subsequent standards included in this series. Note 1: Units of wavelength in this document are exclusively in nanometers (nm). Note 2: Subtended angles are denoted by the full included angle, not the half angle.



ANSI/IESNA RP-29-06

Lighting for Hospitals and Health Care Facilities

This Recommended Practice revises and replaces IESNA RP-29-95, Lighting for Hospitals and Health Care Facilities, published in 1995. Additional material on this topic can be found in Chapter 16 of the IESNA Lighting Handbook, Ninth Edition.1
It is hoped that this latest Practice will provide guidelines for good lighting, stimulate the producers of lighting equipment, and inspire the designers of lighting systems so that the sick and infirm will have a more comfortable and enjoyable recovery environment.
The IESNA Committee for Health Care Facilities seeks to continually improve this Practice and welcomes suggestions. Previous publications issued by this Committee had the benefit of input from the late Dr. William C. Beck. This unique medical practitioner also appreciated the art and science of lighting. He applied his effort and imagination to improve hospital lighting. Much of Dr. BeckÆs research remains in this edition of the Practice, with new information provided by the Committee members listed in the roster and by other IESNA Committees. We cannot rest. We must continually seek ways to introduce new technology development and trends in a timely manner.


ANSI/IES RP-22-11

Tunnel Lighting

A tunnel is a structure over a roadway which restricts the normal daytime illumination such that the driver's visibility is substantially diminished. The information in this Recommended Practice assists engineers and designers in determining lighting needs, recommending solutions, and evaluating resulting visibility at tunnel approaches and interiors.



IES G-1-16

Guideline on Security Lighting for People, Property, and Public Spaces

This document is intended to provide specific guidelines for situations where it has been determined that security is an issue and is an important determining factor in the design or retrofit of a given property.This publication includes specific sections dealing with critical infrastructure and homeland security. In addition, we have incorporated many of the lessons learned and applied by these agencies throughout.



ANSI Logo

As the voice of the U.S. standards and conformity assessment system, the American National Standards Institute (ANSI) empowers its members and constituents to strengthen the U.S. marketplace position in the global economy while helping to assure the safety and health of consumers and the protection of the environment.
