Shopping List:
LED light fixture
Electrical mounting box

Steps:
1. Before doing any electrical work, always shut off power to the house at the main breaker.
2. Trace the mounting box on the ceiling where the light fixture will be mounted.
3. Cut out the traced hole with an oscillating saw.
4. Determine a location for the light switch. It should be 48” from the floor.
5. Trace the electrical box for the switch and cut it out the same way as the mounting box.
6. Locate a source of power for the switch, either at a junction box or at the main electrical panel.
7. Connect the electrical wire to your source of power using the pliers and wire nuts and fish it through the joists until it reaches the light switch. Secure the wire to the joists with electric staples.
8. Drill through the floor in the correct stud bay and send the wires for the switch and the light up to the switch using the fish tape.
9. Mount the electrical box with Madison bars in the wall and wire the switch.
10. Screw the switch into the box and then cover it with the cover plate.
11. Cut a temporary access hole in the wall and fish wires from the fixture mount in the ceiling to the temporary hole, and then from the temporary hole through the joist back down to the basement where the switch was wired.
12. Mount the electrical box in the ceiling with more Madison bars and screws.
13. Wire the new fixture in the box and mount it to the ceiling.
14. Patch the wall where the temporary hole was cut.
15. Turn the power back on.

  1. It says 2018… but how old are really those videos? Everything seems so outdated and fugly… the switch, the ceiling light, the electrical boxes..

  2. question: I noticed he used the metal box with that madison bar. Why not use an existing work box that has the self tightening levers already included? I imagine their was a reason for the route he went when he chose that option.

  3. 'How To' question; Can I install a junction box near my single light fixture (over my island) to tap into it, to install 2 additional ceiling pendant fixtures?

  4. Why not make sure that you are truly saved by Jesus Christ and practice this way. Remorsefully confess with your heart your sins to Jesus Christ who is God and tell Him that you right now are repenting of your sins and you want to be born again of the Spirit from above. Tell Jesus that you are remorsefully sorry for breaking His commandments and that you are begging for forgiveness from Him. Allow His blood from the cross to wash away your sins. After this is done with your heart successfully the Holy Spirit will come to live within you and He will rebuild you from the inside out.

    Look for signs that you are saved. Things like spreading the good news from Jesus, getting other people saved, a craving for the word of God, reading the Bible, etc… These things are known as a calling and fruit bearing. If you're not bearing fruit then keep doing it. Sometimes it takes time to get saved. Read Matthew chapter 13 from the King James Bible. God bless!!!

  5. Save money and get a celling fan rated box to put in and a small chunk of chain to hand the original light by just hacking off the end of the cord turn those wires to life just as if it's like a chandelier.

  6. Nice install. Never heard of "madison bars" before. We have 3 external lights that are really LED panels–we like them (though they do have an industrial/commercial look, which wouldn't suit everyone).

  7. Hello I bought 2 led lights that have a short cord that can be plug in outlet with on and off switch, but it also comes with cable that can be wired. It's nice that this can be plug in outlet and haclve an on and off switch. The problem is that cord is only 2 ft long.
    I have a ceiling fan with light in garage. I control it with light switch from inside house. If I decide to wire the two new led lights can i tap it from ceiling fan? That way when I flip light switch on it will turn on ceiling fun and new led lights too? Do I have to get into attic to do this?

  8. I'm so glad he isn't on the show any more. In all my years of electrical work, If I was hiring, I believe that the only place his job application would be would be in the trash can.

  9. Pro Tips: NEVER use a power tool to cut blindly into sheetrock. You could easily cut through a concealed wire. Instead, use a hand held keyhole saw. Also, do not use those metal boxes with those flimsy metal mounting straps. It is much better to use "old work" plastic boxes that will mount securely to the sheetrock. .

  10. If you don’t know to shut off the power or measure to put the light in the center of the ceiling you shouldn’t be watching this video. It’s a good video for a guy with some tools and common sense. Also anyone who puts a ceiling fan up without checking the box installation first deserves what ever happens to them.

  11. Now for the first time she doesn't have to stumble through a dark room to turn the light on. A electrical feature the rest of us have enjoyed for about 70 years.

  12. This video is terrible. Can’t see the whole picture of what’s going or coming from where – with the way they did the video edits. Also how is the switch connected to the fixture if it’s two separate wires connected to two different locations

  13. Good video as always but don't like that he cuts through the main beam to pass wires. The beam already showing signs of wear and tear and lost strength over the years.
