Seven Strategies to Mitigate the Negative Effects of Outdoor Light at Night

Seven Strategies to Minimize Negative Impacts of Outdoor Light at Night

This resource provides high-level application strategies that go beyond the LUNA product requirements for energy efficiency program staff, contractors, distributors, and lighting practitioners who are interested in using outdoor lighting that is both energy efficient and reduces light pollution.

Key Takeaways
  • Overview of the types of light pollution that affect outdoor environments.
  • High-level information for energy efficiency program staff, contractors, distributors, and lighting practitioners on outdoor lighting application strategies beyond the DLC LUNA product requirements.
Whitepaper: Proposed Revisions to DLC Energy Reporting Requirements

Whitepaper: Proposed Revisions to DLC Energy Reporting Requirements

This whitepaper describes various proposals to make DLC requirements and recommendations for energy reporting more useful to a broader audience. The proposals are based on the new ANSI standards and on input from a working group convened in Q4 2021 comprised of representatives from DLC member efficiency programs and DLC industry partners.

Key Takeaways
  • Energy efficiency programs have varying requirements for energy reporting, creating burden for manufacturers to create a unique reporting function for each program.
  • This whitepaper describes various proposals to make DLC requirements and recommendations for energy reporting more useful to a broader audience.
  • These proposed changes are being made available in advance of a public comment period so that stakeholders can consider implementation and prepare accordingly.

Non-white/Amber Light FAQ

This FAQ document answers questions such as: what are the benefits of non-white light, why are non-white light sources not currently included in the LUNA Technical Requirements, and what are the necessary steps for the DLC to consider including these sources?

Key Takeaways
  • What are the benefits of using non-white light?
  • Why aren't NWL sources currently included in the LUNA Technical Requirements?
  • What are the necessary steps for the DLC to consider addressing NWL in LUNA?

Executive Summary: Non-white Light Sources for Nighttime Environments

This executive summary pulls out the most important takeaways from the DLC's whitepaper, "Non-white Light Sources for Nighttime Environments." This summary is designed for those who do not want to dig deep into the science, and includes an overview of current recommendations for NWL sources in outdoor lighting applications and what you need to know about the state of NWL research.

Key Takeaways
  • Environmental impact of NWL in outdoor environments.
  • Summary of findings from the DLC's NWL market review.
  • What you need to know about the state of NWL research and NWL knowledge gaps to keep in mind.

Whitepaper: Non-white Light Sources for Nighttime Environments

The lighting industry needs an integrated approach to solving the unintended negative consequences of light pollution on the natural environment. This whitepaper describes the landscape for part of that solution: non-white light LED sources. Existing lighting standards must be updated to include NWL sources in order for the DLC and other stakeholders to evaluate these products using a consistent framework. The whitepaper outlines the necessary developments required for the DLC to address these types of products in the future.

Key Takeaways
  • The lighting industry needs an integrated approach to solving the unintended negative consequences of light pollution on the natural environment.
  • Variation and lack of standardization in NWL lighting and LED chip terminology and metrics make inclusion of NWL in the LUNA Technical Requirements impossible at this time.
  • Recommendations for standardizing NWL metrics and terminology in the lighting industry.
