What cabling should I run for LED panels with a 0v-10v dimmer?
I would use 1 run to the fixture then daisy chain them just like any other install.  The low voltage can run in the same cable because all the conductors are insulated for 600v so that would be code compliant. Make sure when you connect your 0-10 you connect them all the same. reversing 1 can damage that one and prevent the lights from going full power (a short takes mine down to ~10% light output) took a while to figure this out as the apprentice only mis wired the last 2 of 20.
All the lights came on at a low level 1 fixture damaged 1 ok. The damaged one no longer was dimmable but works at full power so we put in an area we did not vary the lighting.
