IES Introduces Horticultural Lighting Standard

The Illuminating Engineering Society (IES) recently introduced ANSI/IES RP-45-21 Recommended Practice: Horticultural Lighting. This standard 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.

“Horticultural lighting is a science in its own right, bridging horticulture, botany, and illumination engineering,” explained Ian Ashdown, chair of the IES Horticultural Lighting Committee. “We wrote this document with one purpose in mind: to provide a framework for discussions between horticulturalists and lighting professionals.”

Included in the Lighting Applications Standards Collection and published in consensus by the IES Horticultural Lighting Committee, this document is essential for lighting professionals interested in horticultural lighting for greenhouses, indoor farms, and building atria.
