DC and PoE Lighting

DC and PoE Lighting

DC (direct current) and PoE (power over Ethernet) lighting systems are two new classes of lighting systems with significant potential benefits. By using DC rather than AC power, these systems have potential to reduce electrical losses from AC to DC conversions, to integrate directly with DC generation sources such as solar and batteries, to reduce installation costs, and to connect more readily to IT infrastructure for advanced lighting control. A challenge in assessing the performance of DC and PoE systems is understanding and quantifying the overall system efficiency due to a system architecture that may include remote power sources and different size wiring. 

The DLC is currently developing a policy that would enable luminaires and lamps that are powered by DC or PoE to be qualified and listed on the DLC SSL Qualified Products List (QPL).

Desired Outcomes and Benefits

SSL QPL

New policy enables high quality DC and PoE lighting products to be qualified and listed on the DLC SSL QPL.

microscope

The policy includes clear definition(s), performance criteria, and testing requirements to ensure listed products are high quality and energy efficient.

specify
The policy, in combination with supporting guidance, provides a clear methodology for efficiency program administrators and others to understand and quantify the system efficiency and electric load impacts of installing a DC or POE lighting system. 
 
tools
Energy efficiency program administrators and others support the installation of high quality, energy efficient DC and PoE lighting products in their lighting rebate or procurement programs.
gains
DLC listing of DC and PoE products in combination with utility rebates leads to greater market adoption advanced lighting controls that integrate and systems that integrate with clean energy generation sources.







 

 

 

Next Steps
