Lighting Junction Box Kits

For ceiling lights wiring, prefer a RACO 175 box, 2 1/8” deep, offering ability to securely capture wires that enter the box, from within the box. Find no reason to electrically ground this box. Where this ubiquitous box is designed for capture of jackets of heavy Romex cables, let there be jackets that surround and restrain cables much smaller than 14/2 Romex. Wish further that, as in Japan, lighting wire cables should not include ground wires. Absent ground wires, metal lighting device safety is preserved if a circuit has ground-fault circuit breaker protection.

There is no economy in using boxes 1 1/2" deep.

Want this box to be sealed airtight in the ceiling for purpose including blockage of bugs that would be drawn to any lighting leakage above a luminaire. 

Opportunities for box-mounted LED lighting include the replacement of a can light or a clip-in edge light.
