scope:

This standard specifies the minimum requirements for installation of Power over Ethernet (PoE) lighting systems to ensure minimal energy losses. A typical PoE lighting system uses standardized ethernet twisted pair cable (e.g. category 5e cable) to connect powered devices (PDs), such as luminaires, to DC power source equipment (PSE) (e.g., network switch) without the need for AC line voltage power to the luminaires. The ethernet cable also carries data for control and monitoring of the luminaire.

The energy efficiency of a PoE lighting system depends on three elements: PSE efficiency, PD efficiency, and cable energy losses. This standard specifies cable and installation practices to limit the electrical energy losses of the cable between the PSE and the PD.

Applications include, but are not limited to, commercial, residential, and industrial lighting applications.
