That would only allow PoE+, which limits devices to 25.5W. Speed would be limited to 100Mbps. Still enough for lights, though.
Comment on USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!

Didn’t realize that was part of the spec. But wouldn’t that be 4 devices? 2 wires per device for tx/rx and power +/-.

No. It’s a single twisted pair wire to connect at least 8 devices over a minimum distance of 25m. However the speed is only 10MBit.
