Wafer lights

Do you have a link to that documentation? In one of our CEU discussions it was discussed that all boxes are required to be supported. Maybe it could be argued that these boxes do not fall under Article 314 so 314.23 does not apply.
I don’t have it in front of me.

If you look up installation specs for Sunco wafer lights it specifically says new construction requires securing driver while remodel applications do not.

IMO 314 doesn't apply to these. They are part of a luminaire and anything about this should be in art 410. If art 410 wanted to refer you back to 314 than that's probably fine.

I don't think code has really caught up to this particular product yet, though I haven't actually looked, last I knew all that is addressed that would be similar would be the termination boxes on the more conventional recessed can type lighting.

Like I said earlier I've installed 3 and 4 inch versions of these and is pretty much impractical to permanently attach the wiring box, especially if the only access to it is from the hole through the ceiling. 6 or 8 inch versions not much better but is a little more do-able.
 
Here is one from Halo. Frames available for mounting during new construction. It doesn't mention re models. I did notice you can purchase extension cables (up to 20 feet long) to extend the driver box distance from the light. That means I suppose you could mount the driver box elsewhere (like in a closet). The one from Sunco that @nizak mentioned is also attached.

Sunco does say box does not need mounting in a remodel.

I think the correct code citation would be NEC 410.30(A), as the junction box is part of the luminaire.
