Review on JJC Thin Recessed Ceiling Junction Box for Industrial Lighting Components by Tom Beland

I could install without any problems. They were easy to connect. It's that simple: just cut a 4" hole, wire it up (which was very easy and affordable for me, yours might be different), plug in the lights, pull back the springs and plug in . Those are the ones with very strong feathers. I allowed myself to be clicked and it was like a rat trap, glad it only caught my fingertip.
