New DLC V5.0
February 14, 2019
On January 29, 2019, the DLC published its first draft of new performance standards (V5.0) for commercial LED lighting.
DLC V5.0 focuses on three specific areas: efficacy, quality, and controllability. The V5.0 draft considers the trade-offs between and among efficacy, quality, cost, safety, and human-affecting factors of lighting. The DLC recognizes that quality must go hand-in-hand with efficacy if long-term energy savings are to be realized. The DLC also recognizes the risk of products that push efficacy at the expense of quality factors, which can leave customers unsatisfied and/or negatively impact human health or wellbeing. The first draft of V5.0 is at a conceptual level and does not include detailed product requirements that will appear in the final version.
