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.
