48V connected lighting distributes 48-volt DC power and control communication to LED fixtures over two-conductor cable such as 16/2 or 18/2, with LED drivers centralized into serviceable, redundant power supplies. It is a distinct architecture from Power over Ethernet lighting, which uses Cat5/Cat6 Ethernet cable and network switches.
Doubling voltage halves current and voltage drop, which is what makes 16/2 runs practical. Power and control share a 48V two-wire bus; there is no Ethernet negotiation and no per-fixture IP address.
This is the term where Bryte Light's ecosystem vocabulary leads the market — the disambiguation block against PoE must be the clearest on the site.
