Direct current (DC)-powered lighting technologies including Power-over-Ethernet (PoE) are rapidly gaining steam in smart building applications. More than 25 lighting manufacturers now offer a wide range of luminaires that accept DC or PoE input as a standard option. Vendors of these technologies claim benefits including improved energy efficiency, reliability, and reduced installation costs. But how efficient are these technologies really and under what conditions are these benefits realized? This presentation will share findings of new research by the US Department of Energy into the DC and PoE lighting markets and provide an objective assessment of the technology benefits.
Learning Objectives
1. Characterize the different types and current state of DC lighting technologies including PoE
2. Identify the benefits of DC and PoE lighting technologies and under what conditions these benefits are realized
3. Understand the current limitations and barriers to using DC and PoE lighting
4. Recommended next steps for manufacturers, lighting designers, building owners, and utilities for using these technologies in their projects and programs
