Lighting is easy. Just connect the black wire to black, the white wire to white, and the bare ground wire to the metal housing of the fixture. Of course this is standard 110 v. I use a 12/2 wire with ground. For a fixture, nail a round blue box onto the joist in the place you’d like the light and run the cable to it. For a can spot, just nail the can between the joists where you would like it. The metal arms extend to reach each side. Then just bring the wire into the top and connect with red wire nuts. Good luck. It ain’t hard!
