ATTENTION: I AM NOT A PROFESSIONAL AND NOT RESPONSIBLE FOR YOUR ACTIONS.
First off, I bought the lights, bulbs, wing twists, Romex 14/2 gauge, electrical tape, and screws.
I used the light bulb socket in the garage to tie all the lights into.
This job is made much easier if someone can help you.
1. To start, assemble the leads, etc on the lights and get them ready to mount. There will be a perforated circle in the middle of the light assembly that you need to pop out.
2. Once the lights are ready to mount, flip the breaker off, take out the light bulb, and unscrew the light bulb assembly.
3. Now figure out where you want to mount the lights and use a small screw driver to make a hole in the ceiling where you can locate it in the attic (the hole will be covered up by the light).
4. Use that reference hole to measure to your closest stud and also measure the distance between studs (approx. 16 in.). Now, go back down and use the measurement to locate your first mounting point on the stud. Mark that spot. Take your light assembly and put it on the ceiling and use one of the small holes in the assembly to put your first screw in the stud. Measure down the assembly (in my case 32 in.) to screw the second screw into the stud. Two screws were sufficient for my lights.
5. Now, using the hole in the middle of the assembly (the perforated circle you removed earlier) use a large screw driver to make a good sized hole. It needs to be large enough to fit the Romex through. Take the Romex into the attic and cut enough Romex to reach from the socket to reach the light, plus about 8 in. Go back down and attach the black wire to the black wire and the white wire to the white wire using the wing twists, and then attach the copper to the ground screw in the light assembly. Now you can put the light cover over the ballast and wires.
Repeat steps 1,3,4, and 5 for the remainder of your lights. When finished, move to step 6.
6. In the attic, attach all black wires together, all the white wires together, and all the copper ground wires together with the wing twists, including the wires from the bulb socket (the wires from the switch). Make sure to use electrical tape very generously over the wing twists when finished.
Now you are ready to install the bulbs, turn the breaker back on, and test the lights.
