If you have products on the DesignLights Consortium (DLC) Qualified Products List (QPL) or plan to submit for classification this year, you need to become familiar with the new DLC V4.0 requirement. The change from V3.1 to V4.0 is a significant one and may catch some manufacturers off-guard when they learn products that were previously compliant no longer meet the limits.
More stringent efficacy levels; first substantial change since Jan 2014
Tight transition timeline ahead of de-listing
Option to file using V3.0/V3.1 ended Aug 31, 2016; V4 only moving forward
Products not updated to V4.0 dropped from QPL April 1, 2017
Opportunity to report Rf and Rg color rendition metrics from IEC TM-30
DesignLights Consortium has stated they will make an effort to reach out to individual manufacturers to alert them to products which may not meet V4.0 between Sept and Dec of 2016. However, we at TÜV SÜD urge manufacturers to investigate the status of your products well in advance so as not to run out of time to make necessary upgrades. Keep in mind that once the deadline has passed, and products have been de-listed, this information will be public and accessible via the QPL database. Buyers and users that learn of de-listed products may become unnecessarily alarmed if appropriate measures are not taken in advance. Make the effort now to determine if your products already meet the new requirements, or if minor modification may be required and what application process is necessary to ensure no lapse in your QPL listing.
TO better understand the new requirements and the transition process please reach out to your TÜV SÜD representative. Our staff is happy to help, including no-cost consultation to ensure you’re on the right path. Also inquire about bulk pricing for DLC testing. If you know you will have a number of new models over in a years’ time lock-in a super low price now for multiple tests.
