SSL V4.4: Horticultural Lighting Products

The DLC has developed a draft policy to accept applications for and qualify products designed and marketed for use in horticultural lighting applications.

Horticultural 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. The DLC intends to list Horticultural Lighting products based on output (high- or low-output) and intended use (supplemental or sole-source lighting).

SSL V4.4: DC and PoE Products

The DLC has developed a draft policy that will enable luminaires, lamps, and retrofit kits that are powered by Direct Current (DC) or Power over Ethernet (PoE) to be qualified and listed on the DLC SSL QPL.

DC and PoE lighting systems are two new classes of lighting systems with potential to reduce electrical losses from AC to DC conversions, to integrate directly with DC generation sources such as solar and batteries, to reduce installation costs, and to connect more readily to IT infrastructure for advanced lighting control. The DLC intends to list DC/PoE lamps, luminaires, and retrofit kits on its SSL QPL while differentiating the performance from traditional AC powered lighting.

2nd Draft: NLC Technical Requirements V3.0:

The DLC has developed a second draft of the NLC V3.0 Technical Requirements based on comments received from stakeholders to the first draft, along with discussion at the DLC Controls Summit in March. Highlights of this proposal include revised requirements for both Cybersecurity and Energy Monitoring and revisions to the proposed documentation requirements.
