The ballast went out on one of my recessed ceiling fluorescents. I'd like to replace all 3 of the fluorescents with remodel Halo cans then put in some LED retrofits.
The existing wiring isn't long enough to reach the junction box on the replacement Halo can, so I'd need to extend it with a few more feet of NM-B. (the existing NM-B terminates at the transformer box where it's wire-nutted to the transformers, but the new Halo housing has the junction box for the wiring on a bracket a foot or so from the can).
I'd like to put a metal handy box up in the ceiling to act as a junction box for the wiring extension. I can secure it to Halo can frame in place of the transformer box (which is itself a junction box, the house wiring comes in to that box with wire nuts joining it to each of the transformers). The transformer bracket acts as a cover for this box so I can't just use it as-is as a junction box.
I know that junction boxes are supposed to be "accessible", but does hiding it behind a Halo light count as "accessible"?
(Note that this question seems to be a duplicate of Is a junction box “accessible” if it is mounted behind/above a recessed light housing?, but the answer on that question said to use the built-in Halo fixture junction box, so it didn't really answer the question about whether or not it's ok to put the junction box there)
