DC lighting is recognized as the optimum direct load for renewable power output.  Because lighting accounts for approximately 50% of building power usage, “Direct-Coupling” DC lighting to renewables (solar, battery storage) unlocks grid resilient strategies to optimize lighting security, cost control, carbon reduction, and load management among multiple distributed energy sources.Resultingly, DC lighting ...

The DC Lighting Advantage: DC lighting is a practical & impactful "Direct Load" for the output of renewable power sources that can optimally catalyze energy, efficiency, economic & environmental benefits for microgrids and building power infrastructures, adding sustainable value toward empowering grid resiliency & maximizing the value of renewables. Optimizing the Value of ...

“DC Lighting is the Key to Optimized Microgrid Solutions” (Pacific Northwest National Laboratory) DC lighting can add sustainable value to building power infrastructures and microgrids to empower grid resiliency & optimize the value of renewables. Fundamentally, a DC lighting grid “Direct-Coupled” (DC-to-DC) with renewable power (solar/battery storage) unlocks optimized grid ...

Seven smart building manufacturers announced that they are joining forces to bring more attention to the value of Power-over-Ethernet (PoE) lighting and technology. The companies are collaborating to create an industry organization known as the PoE Consortium.The partner firms stated collective mission is "to educate stakeholders on the sustainable benefits of ...

What is PoE (Power over Ethernet)? Power over Ethernet (PoE) is technology that passes electric power over twisted-pair ethernet cable to powered devices (PD), such as wireless access points, light fixtures, IP cameras, and VoIP phones in addition to the data that cable usually carries. It enables one RJ45 cable ...
