DesignLights Consortium Releases Final Technical Requirements Table V4.0

Design Lights Consortium

 

June 05 2016

The just-released 4.0 version revises efficacy requirements in an effort to keep pace with changes in the market and support the energy savings goals and other needs of DLC members. 

Previous revisions that were finalized in 2014 and 2015 focused primarily on restructuring the technical requirements table, establishing requirements for the DLC Premium classification, enabling a pathway for products to be qualified under new Specialty Use designations, and adding categories to the Technical Requirements Table. The last major revision to efficacy levels for the DLC Standard classification was announced in April 2013, and took effect on January 1, 2014.

The solid-state lighting market has grown and product performance has improved significantly in the nearly three years since the V2.0 efficacy levels were established. To keep up with these performance improvements, the V4.0 revision focuses primarily on efficacy. While each DLC member efficiency program operates independently and have its own specific needs, this amount of revision is necessary for most programs to be able to differentiate product performance to continue offering incentives for DLC qualified products.

With the change in standard requirements, as well as product development and evolution in efficiency programs, the DLC has raised the requirements for Premium as well to serve the needs of its membership. The objective for the Premium classification is to identify the top 5-10% most efficacious products in any given category.

Among the changes, the V4.0 Technical Requirements document includes a placeholder for a new Table 6, identifying “Allowances” for specific product types. In the feedback received from stakeholders regarding the draft proposals released for comment in February, significant commentary discussed certain features of specific products that related to quality, but that made meeting the proposed efficacy levels more difficult to achieve relative to products without those features.
