What DesignLights Consortium does

The DesignLights Consortium (DLC) is an independent nonprofit organization, operating under the 501(c)(3) entity Efficiency Forward, Inc., that maintains the largest verified registry of high-performing commercial LED lighting, horticultural lighting, networked lighting controls (NLC), and LUNA (Light Use for Night Applications) outdoor products in North America. Founded in 2015 as a spinoff from Northeast Energy Efficiency Partnerships (NEEP) and headquartered in Medford, Massachusetts, DLC develops and stewards four Qualified Products Lists (QPLs) - SSL/LED, Horticultural, NLC, and LUNA - against which manufacturers submit products through the MyDLC portal for independent third-party review against published technical requirements covering efficacy, controllability, and quality. The organization also runs a surveillance testing program for ongoing quality assurance and develops requirements through a transparent stakeholder process involving public comment periods, technical committees, and working groups.

The DLC's core technology is the QPL database and qualification engine, supported by technical requirements versioning (SSL V6.0, LUNA V2.0, Hort V4.0, NLC V5.2), the MyDLC submission portal, and integration resources for NLC-HVAC interoperability. The organization is funded by two primary revenue streams: recurring membership dues from nearly 700 utility and energy efficiency programs across the U.S. and Canada, and transaction-based product application and listing fees paid by manufacturers (Level 1 single product, Level 2 family grouping, and private label). The QPL itself is freely accessible to the public with account registration, positioning DLC as a neutral, third-party verifier rather than a paid data vendor. A third-party estimate from NAILD places DLC's annual revenue at approximately $10 million, consistent with a small team of 11-50 employees whose collective lighting expertise exceeds 200 years.

DLC serves a dual-sided market: utilities and energy efficiency programs use the QPLs to validate product eligibility for rebates and ensure ratepayer dollars fund verified efficient products, while lighting manufacturers pursue DLC qualification to access utility rebate channels and signal product quality to specifiers, designers, and building owners. Government customers, including the U.S. General Services Administration which mandates DLC-qualified products under P100 Facilities Standards, add a regulatory anchor. Strategic governance is provided by a board with representation from Microsoft, Lawrence Berkeley National Laboratory, Ernst & Young, Centrica Business Solutions, and Upciti, alongside active participation in IES, ASABE, NEMA, and NCQLP standards bodies, reinforcing DLC's authority as the de facto North American lighting qualification standard.

Revenue model

1. Membership Dues: The DLC is supported and funded by efficiency program member organizations throughout the US and Canada. Members include utilities, energy efficiency programs, and regional/state organizations that pay dues to participate and influence DLC policy development.
2. Product Listing Fees: Manufacturers pay application and listing fees to have products reviewed and listed on the QPLs. These fees support program operations, technical research, policy development, and stakeholder engagement.

Core offering

DesignLights Consortium operates four Qualified Products Lists (QPLs) that verify high-performing commercial lighting and control products for energy efficiency, controllability, quality, and light pollution mitigation. Manufacturers submit LED lighting, horticultural lighting, networked lighting control systems, and LUNA outdoor lighting products with accredited test reports for independent qualification review. The verified data is published as publicly searchable QPLs used by nearly 700 utility and energy efficiency programs to validate rebate eligibility.

Product overview

The DesignLights Consortium (DLC) operates a multi-list Qualified Products List (QPL) ecosystem comprising four distinct product categories: the SSL/LED QPL (the world's largest verified list of high-performing commercial LED lighting products), the Horticultural QPL (for CEA/growing facilities), the NLC QPL (for networked lighting controls enabling connected buildings), and the LUNA QPL (for dark-sky-friendly outdoor lighting). Manufacturers access the MyDLC portal to submit products for qualification review against DLC's technical requirements. The DLC also provides surveillance testing, application support, and NLC-HVAC integration resources. The organization is an initiative of Efficiency Forward, Inc., a nonprofit 501(c)(3).

Products and services

• SSL/LED Qualified Products List (QPL) The world's largest verified list of high-performing commercial LED lighting products. Manufacturers submit LED luminaires with accredited test reports for independent third-party qualification against DLC technical requirements covering energy efficiency, controllability, and quality. Used by nearly 700 utility and energy efficiency programs to validate rebate eligibility and adopted by U.S. federal facilities standards.
• Horticultural Lighting Qualified Products List (Hort QPL) Verified list of energy-efficient LED lighting products designed for horticultural and controlled environment agriculture applications. The QPL supports growers and utilities seeking to validate energy-efficient lighting for indoor farming, greenhouse, and vertical farm operations, with listed fixtures up more than 54% since 2020.
• Networked Lighting Controls Qualified Products List (NLC QPL) Verified list of networked lighting control systems for commercial buildings that enable energy savings, building optimization, and connectivity to support carbon reduction goals. Launched in 2018 to support energy savings across North America.
• LUNA Qualified Products List (LUNA QPL) Verified list of outdoor LED lighting products meeting additional performance criteria that minimize light pollution while maintaining energy efficiency, protecting dark skies and nocturnal environments. Required by the U.S. GSA P100 Facilities Standards for federal building outdoor lighting.
• MyDLC Portal Online portal for manufacturers to create accounts, submit product applications for qualification, manage product listings, and access QPL data. Required for submitting SSL, Hort, NLC, and LUNA products for DLC qualification review.
