Memo: Clarifications to the 2020 Report: “Energy Savings from Networked Lighting Control (NLC) Systems With and Without LLLC”
This memo provides clarity on interpreting the presented information and further elaborates on key points in the 2020 Savings Report.
Key Takeaways
- The control savings factors (CSFs) in the 2020 report represent average savings across a diverse set of projects, which include both optimally and sub-optimally programmed systems. Energy efficiency programs that implement mechanisms to specify or verify proper NLC system programming can expect higher savings, as CSFs are influenced by system setup and optimization.
- High-end trim and other control strategies deliver distinct savings. While high-end trim reduces the lighting load first, other strategies save energy from the remaining load. To maximize savings, EE programs can incentivize and measure these strategies separately, using the CSFs provided in the updated report for independent assessment.

Key Takeaways
- Outdoor Lighting Ordinances for Mitigating Light Pollution in the US and Canada
Requirements for Submitting SSL Product Images
The DLC accepts and displays product images on the Solid-State Lighting QPL (SSL QPL) to allow energy efficiency program staff to cross-reference product specification sheets with QPL listings more easily. Image submission is not required for qualification. This resource details the DLC's requirements and style guidelines for SSL product images.
In this Resource
- Requirements and guidelines for formatting and submitting product images to display on the SSL QPL.
Guidance for Using Allowances
This resource provides examples of the testing required to qualify products to the SSL QPL using efficacy allowances, and explains how those allowances may affect the product’s QPL listing.
Key Takeaways
- Provides four example scenarios for using efficacy allowances when qualifying products to the SSL QPL.
Key Takeaways
- Outdoor lighting design
- Effects of light pollution on wildlife
- Inequities of outdoor lighting
