Testing and Qualification Requirements for Horticultural Lighting

The Design Lights Consortium (DLC) has developed requirements for qualifying horticultural lighting products for inclusion in the DLC’s Horticultural Lighting Qualified Products List.

A few of the critical performance and reliability requirements to achieve DLC listing include:

Efficacy > 1.9 μmol/J between 400-700nm
Long-term performance: Q90 > 36,000 hours photon flux maintenance
Driver Lifetime: > 50,000 hours
Warranty: > 5 years

A 2020 Draft has been proposed that will increase the Efficacy requirement to 2.1 μmol/J and require UL 8800 compliance for safety certification.

In a similar manner, UL 8800, Outline of Investigation for Horticultural Lighting Equipment, is intended to address the unique safety issues applicable to horticultural luminaires, lighting components and grow systems, and represents the first comprehensive set of standardized requirements specifically designed for horticultural lighting equipment. As a result, UL is currently using the requirements of UL 8800 to evaluate horticultural lighting equipment from manufacturers seeking the UL Safety Mark for their equipment and devices.
