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.
Evaluating the Non-Energy Benefits of Advanced Networked Lighting Controls
This resource, which summarizes research commissioned by the DLC and conducted by Skumatz Economic Research Associates, Inc. (SERA), identifies non-energy benefits (NEBs) specific to NLC usage and develops a methodology for assigning them quantitative values.
Key Takeaways
- “Non-energy benefits” of NLCs can enable inclusion of anticipated savings from productivity gains, safety and security enhancements, extended equipment lifecycles, and more in cost-benefit calculations.
- Developing a methodology for assigning quantitative values to NEBs will enable utility incentive program staff and others to use an expanded set of metrics for measuring the cost-effectiveness of NLC implementation.
- Research showed statistically significant non-energy benefits from NLCs for both lighting decision makers and building occupants.
Journal Article: Specifying non-white light sources in outdoor applications to reduce light pollution
This journal article, originally published in Leukos on January 5, 2023, proposes a specification structure for amber light sources to increase the precision of language used in the industry, and encourages lighting standards development organizations to consider standardizing such a system. It also demonstrates that non-white light sources with well-defined chromaticity ranges outside of the ANSI C78.377-2017 quadrangles may be useful for reducing wasted light that causes sky glow, a phenomenon that is associated with approximately $7 billion in wasted energy and nearly 66 million metric tons of CO2 emissions annually.
Key Takeaways
- A call for the lighting industry to consider developing industry consensus definitions and standards for “amber" light sources.
- Methodology for expanding ANSI standard CCT chromaticity bins to include three new bins: 1800K, 2000K, and PC Amber.
- Discussion of why CCT alone is not an adequate representation of the spectral composition of light, and the wide range of potential impacts to sky glow.
