Power over Ethernet (PoE) technology offers the ability to provide low-voltage direct-current (DC) power and communication over a standard Ethernet cable. Several major LED luminaire manufacturers have introduced PoE connected lighting systems in recent years, making this a potentially disruptive technology. A new exploratory study conducted in the Department of Energy’s Connected Lighting Test Bed investigates energy losses in Ethernet cables used between PoE switches and luminaires in PoE connected lighting systems.
