I am finishing the basement of my 1950s duplex this weekend. There are currently four large commercial three tube florescent box lamps that were installed by the previous owner and completely work. However, I am looking to install two 5" LED recessed lamps where each box lamp is currently. In terms of wiring, each box lamp is wired to its own switch and that is how I would like to keep it.

What I am thinking about doing is taking the Romex wire from the switch, to a junction box where it will be split to feed power to each recessed lamp. Is this the way to do it? Is there a wiring diagram somewhere I can see that explains how to do this?

I hope that this makes sense.
