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. Appropriate test procedures, alignment on performance needs, and industry best practices that inform product selection and installation are necessary to inform DLC requirements. While research and standards development is underway, the DLC may develop an interim process for qualifying horticultural lighting products.
The DLC is developing new categories, Technical Requirements, and policies to list horticultural lighting products on the DLC SSL Qualified Products List (QPL).
Desired Outcomes and Benefits
New policy and Technical Requirements enable reliable and efficient horticultural products to be qualified on the DLC SSL QPL.
The policy includes clear definition(s), performance criteria, and testing requirements to ensure listed products are high quality and energy efficient.
Energy efficiency program administrators and others support the installation of high quality, energy efficient horticultural lighting products in their lighting rebate or procurement programs, driving market adoption of energy efficient solutions in horticultural applications.
Growers and specifiers have the data and tools they need to be able to specify horticultural lighting products appropriately.
Utilities are better able to manage increasing energy demand from horticultural facilities through incentive programs for efficient and effective horticultural lighting products.
