?? New Update to LUNA Technical Requirements! We're excited to announce a new update opening up LUNA qualification to eligible luminaires. LUNA now allows eligible luminaires with field adjustable optics to qualify to LUNA as long as the luminaire’s Uplight Rating (U Rating) does not exceed our maximums in any configuration. Products with field adjustable distribution types (e.g., the luminaire can switch between a type 2 and a type 3 distribution by turning a dial) may now qualify to LUNA as of our March 2025 update: https://ow.ly/b33W50VlOii LUNA V2.0 will be released in conjunction with SSL V6.0 Technical Requirements and will have additional updates coming soon. Keep an eye out for Draft 1, which will be available for comment in early April. #LED #outdoorlights #darksky #lightpollution #lighting

Join us next week for our webinar on Hort V4.0 Technical Requirements! Tuesday, March 25, 2pm ET. https://ow.ly/iFjC50VkRiB Hort V4.0, serves to improve the efficacy and quality of lighting products in controlled environment agriculture. Manufacturers, utilities, testing labs, and regulators should note the three key updates in Hort V4.0: ?? Increasing the photosynthetic photon efficacy (PPE) threshold ?? Removal of lamps as a category eligible for the QPL ?? Clarifications to various requirements throughout the new policy #manufacturers #testlab #utilities #lighting #CEA #horticulture #LED

?? New Technical Requirements Released for Horticultural Lighting! ?? This update, Hort V4.0, serves to improve the efficacy and quality of lighting products in controlled environment agriculture. The technical requirements were finalized after holding a stakeholder comment period and incorporating feedback. Thank you to everyone who collaborated with us on developing these requirements! Manufacturers, utilities, testing labs, and regulators should note the three key updates in Hort V4.0: ?? Increasing the photosynthetic photon efficacy (PPE) threshold? ?? Removal of lamps as a category?eligible for the QPL ??

?? Unlock More Savings with Connected Lighting + Energy Efficiency Programs! ??? Energy efficiency program administrators: Are you looking to maximize energy savings while streamlining incentives for connected lighting? Our latest resource, Pathways to Connected Lighting, shares best practices and insights. Objectives: ?? Help EE programs achieve savings targets with connected lighting and controls ?? Facilitate the adoption of new incentives for connected lighting and HVAC integration ?? Share best practices from successful DLC member program models ?? Empower EE program administrators to take action Read more about it and download an excerpt here: https://lnkd.in/eckWYig3 Shout out to Dan Mellinger, PE, CEM, Levin Nock, and John Arthur Wilson for their contributions! #utilities #energyefficiency #lighting #NLC #LLLC

This Saturday, March 8 is International Women's Day. At the DLC we are proud to recognize the contributions of women across the lighting industry. Join us in celebrating the women who drive success and make a difference! This year’s #IWD theme, #AccelerateAction, reminds us that there is more work to do and more collaboration needed to achieve gender equality. #IWD2025

??? ?? Save energy with our free toolkit for large commercial buildings! Many buildings are missing out on energy savings if their lighting and HVAC systems are not in sync – it can save over 20% of the whole building load. The DLC created a toolkit to foster collaboration between building owners and operators, electrical/lighting engineers and contractors, and mechanical/HVAC engineers and contractors, who often work independently. The toolkit aims to help them: ?? Understand the benefits of integrating Networked Lighting Controls (NLC) with HVAC systems? ??? Identify the best buildings for integration to maximize energy and cost savings ?? Navigate roles and responsibilities across different teams and building systems ?? Learn from real-world case studies, searchable by building type? ?? Download the free toolkit today! https://ow.ly/ET6f50V2IZj It includes a decision tree, a handbook, a list of case studies, a responsibility matrix, and a project template (construction specification aligned with CSI Division 25).

This #BlackHistoryMonth the DLC recognizes the work of Granville T Woods (1856-1910), who is often referred to as "Black Edison." He was a prolific inventor who held over 60 patents over the course of his life and improved communications on electric transit systems in the US. One of his patents, related to telephones and telegraphs, was bought by Alexander Graham Bell. The funds allowed him to continue his research into additional improvements to dispatch and communications in rail systems. We are thankful for his work and perseverance, working during a time when few African Americans were given proper credit for their contributions. https://lnkd.in/efn-mRmp

?? We're holding a webinar this week - on Feb 26, 2pm EST! Join the DLC and NEEA to discuss new updates to the 2020 report, “Energy Savings from Networked Lighting Control (NLC) Systems With and Without LLLC”. Key updates include: ? A clearer definition of luminaire level lighting controls (LLLC) as used in the study ? More nuanced breakdowns of control savings factors (CSFs) ? A refined distinction between high-end trim savings vs. occupancy sensing & daylight harvesting This webinar can help EE program managers avoid misinterpretation when designing incentive structures and assessing real-world project performance. As technology advances, ongoing updates and dataset refinements will be critical in maximizing energy savings. ??Register for the webinar here: https://ow.ly/ERgt50V2Igq Presenters: Bagwat K Mohan, PMP, Yao-Jung Wen, Chris Wolgamott #LLLC #Lighting #energyefficiency #NLC Northwest Energy Efficiency Alliance (NEEA)
