Guidance for Submitting Horticultural Product Images
Because product design and form factor can vary considerably between manufacturers and brands, the DLC requires a product image to accompany each Hort V3.0 QPL listing. This guidance document details the DLC's requirements and style guidelines for product images.
In this Resource
- Requirements and guidelines for formatting and submitting product images to accompany Hort V3.0 applications.
NLC5 Cybersecurity Overview
UPDATED 12/21/2022 - CSA/ANSI T200 updated from a service to a standard. Through research and outreach, the DLC has identified several cybersecurity standards and services that satisfy the cybersecurity criteria in the NLC5 Technical Requirements. To help manufacturers and other users find an appropriate standard and/or service for their networked lighting control system, this resource provides additional information on each standard and service and summarizes their application.
Key Takeaways
- Summaries of cybersecurity services and standards recognized by the DLC (updated 7/14/22 to include PSA standard)
- Descriptions of the primary application and timeline for certification of the cybersecurity standards listed in Tables CS-1 & CS-2 of the DLC NLC5 Technical Requirements
