Just for fun for anyone following this thread. I agree the Ethernet in the ceiling is likely DMX over Cat5 cable.
That being said there are some really cool new technologies coming out to run LED fixtures over Network cable.
Basically Low Voltage power and signal over a single Cat6 cable from a driver box to power LED downlights in an architectural setting and you can even daisy chain 4 fixtures with network cable and still get individual control of each.
ETC just came out with this the other month: https://www.etcconnect.com/Navis-F-Drive-System.aspx?utm_source=Hero&utm_campaign=Navis-F-Drive
You literally plug network cable into the power supply in an equipment room and then the other end of the network cable into the light and it can be dmx controlled from the power supply.
Found the picture I couldn't find before:
