The DLC Qualified Products Lists are the largest verified lists of high-performing and energy-saving LED lighting solutions in the world. Qualified products undergo thorough vetting and review by DLC experts to ensure they meet our rigorous energy and quality requirements. Choose between solid-state lighting products, light pollution-mitigating lighting products, horticultural lighting products, or networked lighting controls below to begin your search for energy efficient lighting solutions. August 24, 2023 – A DesignLights Consortium (DLC) study published today underscores the energy savings potential of networked lighting controls (NLCs) and recommends revising energy efficiency incentive models to capture the full benefits of controlled lighting. A summary of the study, which emphasizes the value of pairing NLCs with HVAC systems in large commercial buildings, is posted on the DLC website.

Screw-Base Replacements for HID Lamps

DLC has added more products to our LUNA QPL, continuing to double down on light pollution mitigation to support ecosystems and human communities while still reducing energy consumption. Ecosystem-level harm is preventable with more education and quality alternatives for outdoor lighting. This year, we’re working toward a standard and requirements for amber outdoor lights for the most sensitive environments. There are nearly 300 lighting ordinances in the U.S. alone and growing interest in making better choices regarding light pollution and keeping our skies dark for human health and wellness, views of the night sky, and protection of our natural ecosystems. The DLC is committed to improving energy efficiency for commercial lighting throughout North America, and to making a positive climate impact worldwide.

Solid-State Lighting

We’re committed to pushing the industry forward and investing in future-focused solutions, which is why we’re a certified Climate Neutral company and will be Climate Positive by 2025. Testing for DC and PoE products must cover all areas of investigation as is required for AC family groups. All DC and PoE products must be submitted as a Family Group, regardless of the number of products submitted. Learn how we’re driving energy efficiency and lighting quality in the commercial space across North America. According to the US DOE, the annual electricity consumption of all indoor US horticultural installations in 2017 was 5.9 TWh – approximately equal to the annual usage of more than half a million US households.

Founded in 2013 by a groom and a groomsman who had a frustrating rental experience, The Black Tux is reinventing formal wear. We help people stand out for the right reasons by designing modern suits and tuxedos that look great, fit better and can be ordered online without a trip to the tux shop. As the DLC processes applications for V5.1, we have encountered the need for minor corrections, clarifications, and policy changes.

Using Connecticut and Arizona as regional models, the study concluded that the benefits of acquiring all cost-effective savings from NLCs would be significant enough to make a noticeable impact on utility efficiency program budgets. Businesses in Connecticut could receive almost $1.2 billion in net benefits by 2030, while businesses in Arizona could receive net benefits of $217 million. Selecting a QPL listed product may also mean you are eligible for money-saving rebate from member utility companies!

The Design Lights Consortium was first used to educate lighting distributors about high performance T8 fluorescent lamps. Today, the DLC has turned its attentions to LED lighting because it became more available and increased its marketshare. When purchasing energy-efficient lamps and lighting fixtures, you may come across some that say "DLC Listed". Tell us about what you are trying to accomplish and one of our certified lighting specialists will follow up with you by the end of the next business day with product recommendations to suit your needs. That’s why the DLC works with our members and industry experts to establish performance thresholds and to create new programs that work for all of our stakeholders.

Our sunny Santa Monica office features a fully built out studio for recording, live streaming, and live events which is available to the staff to further their craft, experiment, and enjoy on off hours. The DLC requires specific testing and reporting to qualify modular products with external power supplies. The DLC lists modular products with external power supplies by unit, with unit-level performance data for light output characteristics.

In July 2015, the Design Lights Consortium reportedly delisted 1,220 products due to misrepresentation, according to their Industry Update newsletter. The QPL also shows a directory of delisted products, since consumers will want to avoid them. The DLC Workplan Timeline displays our progress toward the current initiatives in our pipeline.

Quality of light encompasses the characteristics of lighting that impact productivity, performance, comfort, mood, safety, health, wellbeing, and more. V5.1 includes new requirements for spectral quality and light distribution that will improve the quality of light of DLC listed products. The V5.1 lighting controllability requirements support additional energy savings while promoting better quality of light for people living and working in the built environment. V5’s phased approach to incorporating quality of light metrics on the QPL will ensure that high-quality products are listed, superior performing products can be differentiated, and additional energy savings are realized.

Find out what networked lighting controls can do for your facility while saving up to 50% more energy than LED lighting alone. Search over 80 categories of indoor and outdoor commercial LED products, including options that minimize light pollution. DLC applications require that product testing be conducted at an accredited laboratory appropriate for the performance being evaluated. These tests may include in situ measurement tests (ISTMT), LM-79, LM-80, LM-84, or compatibility tests for four pin-base replacement lamps for CFLs. V2.1 also allows QPL listing for DC-powered fixtures and describes how to test and report on them in place of the typical equivalent alternating current (AC) testing and reporting. In response to stakeholder comments, the DLC changed this section of the policy from Draft 2, with revisions to the testing and reporting range of loading points required for the test power source report.

The DLC carefully evaluates each of our initiatives to maximize positive impact on the environment and on the industry. We work with market experts, manufacturers, energy efficiency programs, and other industry stakeholders to establish requirements that keep the lighting industry at the forefront of sustainability and carbon reduction efforts. Learn how you can contribute to policy development, join a DLC committee, qualify your products, or simply stay up to date with our latest efforts the DLC. With aggressive utility support, networked lighting controls have the potential to save up to half of the remaining lighting load after an LED lighting retrofit – and can enable lighting efficiency programs to be maintained twice as long as compared to support for LED fixtures and lamps alone.

Over the years, our work has evolved to include advances in critical areas of lighting quality, such as color, glare, and controllability for both light preferences and energy savings. Controlled environment agriculture is a rapidly growing sector that uses horticultural lighting to optimize crop production and reduce environmental impact. Horticulture LED lights are one of the most energy efficient and effective options for artificial lighting for plants, as they can deliver the right spectrum, intensity, and duration of light for different crops. The horticulture lighting market is expanding and growers need high-quality products with reliable performance claims.

The DLC requires additional testing and reporting to qualify dimmable and field-adjustable products. Dimmable and field-adjustable product applications must include testing to demonstrate the products meet DLC requirements at full output. The testing for white-tunable products must be provided to cover all areas of investigation as with non-color tuning family groups, plus additional testing across the color-tunable range for the least efficacious product.

Two states with cannabis-specific energy efficiency regulations offer a compliance pathway that requires use of the DLC’s Horticultural Lighting QPL. By adding QPL eligibility pathways for additional product categories, the DLC’s V2.1 Horticultural Lighting Technical Requirements offer licensed cannabis cultivators in these states more options for regulatory compliance. One research example is our August 2023 “Economic Potential of Networked Lighting Controls in Commercial Buildings,” and an example of a tool is our light pollution ordinances map, which tracks local outdoor ordinances and bylaws across North America.
