Junction box question
If you used a 4 inch junction box to transition from rigid conduit to flexible conduit before reaching the junction box built into the light fixture, you can string the wires with no splices or wire nuts in the square 4 inch junction box.
Meanwhile the 4 inch square junction box as shown at the left in the picture above, with connections in it, may be needed if you are running 12 gauge wiring and need to daisy chain given the small space in the junction box in the light fixture.
Another disadvantage of the extra 4 inch junction boxes is the need to have their covers exposed on the ceiling. The light fixture needs no hole other than the round hole for the light.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
