Horticultural Lighting V1.2

Horticultural grow facilities are quickly becoming the fastest growing electric load for many utilities, with lighting representing the greatest portion of that load. Well-designed horticultural lighting products have the potential to save energy while optimizing plant growth and health. 

In order to stay up to date with emerging technologies and the state of the industry, the DLC published the following minor revision to its Testing and Reporting Requirements for Horticultural Lighting as Version 1.2, effective October 21, 2019.

Final policy goes into effect
