Due to a high volume of SSL and Hort applications, initial and comprehensive review timeframes are currently extended by 10 days each. Beginning April 11, review priority will be given to applications updating V5.0 products to V5.1, which may also impact review timeframes for all other SSL application types. Click here for more details about SSL application review timeframes, and here for more details about Hort review timeframes. Thank you for your understanding!

Our Initiatives

The DLC is on a mission to optimize commercial lighting by saving energy, improving product quality, and enhancing the end-user experience in the built environment. Our initiatives revolve around the creation of trusted requirements to ensure that qualified lighting technologies are both high quality and energy efficient. Learn more about how we’re collaborating with industry experts, stakeholders, and efficiency program members to integrate lighting into smart cities of the future and meet carbon reduction goals.

Accelerating the Market Transition to Efficient LEDs

The DLC’s solid-state lighting program is home to the largest and most influential list of high-performing commercial lighting products in the world. Our SSL Qualified Products List improves both consumer confidence and sustainability of the lighting industry as a whole – with an end goal of accelerating the installation of energy efficient, better quality lighting for people living and working in the built environment.

Integrating Networked Lighting into the Built Environment

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. In addition to developing tools that reduce barriers to adoption, we’re promoting this energy saving technology as the gateway to enable connected buildings that support carbon reduction goals.

Transforming Horticultural Lighting from the Ground Up

According to the US DOE, the annual electricity consumption of all indoor US horticultural installations in 2017 was about 5.9 TWh – approximately equal to the annual usage of more than half a million US households. With energy consumption from horticultural facilities continuing to grow, we’re creating tools and resources to position controlled environment agriculture as a leader in energy efficiency.

Addressing Light Pollution

As a part of our Solid-State Lighting Program, the DLC’s new LUNA requirements provide a dark sky friendly option for specific categories of outdoor solid-state lighting so that lighting decision makers can identify products that save energy AND minimize sky glow.
