The following appeared on the Design Lights Consortium website on October 18, 2018:
Due to unforeseen delays in development, the effective date for Technical Requirements V4.4 will be postponed until the end of the month. The postponed effective date affects DLC requirements for horticultural lighting products, DC/PoE products, and field-adjustable light output products. The DLC will send notice of the new effective dates shortly.
Please continue to use Application Forms for Technical Requirements V4.3 at this time, and until Technical Requirements V4.4 go into effect. We sincerely apologize for any inconvenience.
The announcement comes 18 days after the DLC posted the new requirements on its website. The DLC hosted a series of webinars to explain the new requirements. You can view them by clicking here.
