On September 15, 2020, DLC released the official version of v2.0 standard for grow light or horticulture luminary, which will be implemented on March 21, 2021. Before that, all DLC applications for grow lighting fixture will continue to be reviewed according to v1.2 standard.

Grow light v2.0 official update content is as below:

01.Keep the requirements of version v1.2, PPE ≥ 1.9 μmol/j, unchanged

In the first draft of V2.0, DLC plans to increase the photosynthetic photon efficiency of PPE to 2.10 μmol/J. However, after collecting the feedback of the draft, DLC realized that the horticultrue lights, like LED grow lighting fixture, HID grow lighting fixture, etc, is an emerging market. For the sustainable development of the market, DLC decided to keep the current v1.2 standard of PPE photosynthetic photon efficiency value unchanged, while maintaining the tolerance of – 5%.

In addition, DLC adds two optional reporting parameters, 280-800nm photon flux parameter and efficiency parameter. The radiation in this range is usually related to the effect of plant growth and development.

02.Revised terminology to comply with ASABE (S640)

DLC revised some policy terms to better align with the American Society of Agriculture and Biological Engineering (ASABE) ANSI/ASABE S640 definition.

03.安全认证要求符合UL8800

The safety certificate obtained for plant grow lighting products must be issued by OSHA NRTL or SCC and comply with the standard ANSI/UL8800 (ANSI/CAN/UL/ULC 8800).

04.TM-33-18 data is required

DLC will request to provide PPID and SQD data information derived from the TM-33-18 standard.

05.Family Series Application

DLC will accept applications for the Family series of grow lights in order to reduce the burden of testing and application fees.

Requirement for the product as a family

• The same LED must be used;
• Must have the same structure, including electrical, optical and heat dissipation structures;
• Can contain different drivers;
• Under the condition of not affecting the heat dissipation, different mounting brackets can be included;
• Must contain a complete and detailed model name;
• A model name can only correspond to one brand. When the product is sold under multiple brands, the model name needs to be distinguished accordingly.

06.Private Label listing application 

DLC will accept applications for the Private Label listing of grow lights.

07.DLC Logo for grow light

Please contact DLC for how to use the logo legally.
