IES Position Statements are approved by the Society’s Board of Directors and reflect the Society’s official position on lighting related issues that affect our community or the general public interest. They are often interpretations of content or use for IES Standards, however they can also represent official IES positions on lighting issues generated outside of the Society. These position Statements are developed by technical experts within our Standards committees and the Board of Directors, and are free to use and disseminate.
