The DesignLights Consortium® (DLC) members have expressed a need to be able to identify products that may be compliant with California Building Standards Code (Title 24, California Code of Regulations). The DLC is proposing to collect and report specific dimming information to accommodate this need and is seeking industry input on the proposed approach to collecting and reporting this information. Please review the proposed policy below and provide comments or questions to [email protected] by Midnight ET, Friday, May 9, 2014. Proposed Dimming Information to be Collected and Reported The DLC is proposing to collect and report the following information for all products: - Is the product capable of dimming? o This will be indicated as “Yes,” “No,” or “Not Yet Verified.” - If the product is capable of dimming, how does the product dim? o This will be referred to as the dimming type, and indicated as continuous or step. - If the product is capable of continuous dimming, what percentage of full power does the product dim to? o This will be indicated with the lowest level of full power the product dims to – e.g. 10%. - If the product is capable of step dimming, how many distinct steps? o This will be indicated as the number of steps – e.g. 4. Due to the lack of an industry standard testing methodology to verify dimming capability and performance under dimmed conditions, the current proposal does not include performance requirements under dimmed conditions. The DLC will monitor industry progress toward a standard testing methodology and determine if performance information should be reported and/or performance requirements be instituted in the future. Supporting Documentation Manufacturers will be required to self-report a product’s dimming capability, dimming type, the percentage of full power the product dims to or number of distinct steps. Manufacturers must provide a unique model number for each product variation submitted in an application with different combinations of reported dimming information – i.e. non-dimming and dimming capable products may not be represented by the same model number. The DLC will evaluate a manufacturer’s claims of dimming capability by ensuring that the dimming claims are clearly published in the product specification sheet and correspond with the unique model numbers submitted. DLC reviewers will reserve the right to request additional information to demonstrate dimming capability if product specification sheets are not sufficient. Timing The DLC is targeting a final policy release date in the coming months. Manufacturers will be notified when they may begin submitting dimming information to update currently qualified products, as well as a date when new applications will be required to include dimming information for all submitted products. Currently qualified products will not be removed from the QPL if dimming information is not updated. Instead, a product’s dimming capability will be indicated as “Not Yet Verified” until dimming information is provided. The DLC is proposing that qualified products whose dimming information is indicated as “Not Yet Verified” as of January 1, 2015, will be changed to “No” at that time. Cost Due to the need for DLC staff to review and process product updates, there will be a cost for relisting products with appropriate dimming information. While DLC is working to minimize these costs as much possible, there will likely be an application fee for manufacturers seeking to update their data. The structure and fee schedule will be announced as they are determined, based on the final policy that is put into place. Application Processing Time Due to the volume of expected update submissions in June and July, DLC is considering extending the standard turn-around time from the current two-weeks to three-weeks for applications received in this time period. This new review period will apply to both new submissions and update submissions.
