This video demonstrates Installing a new ceiling light in a bedroom where there was no junction box or wiring installed. I used the switch on the wall and rewired the outlets which originally were switched (top outlet controlled by a wall switch) to always powered outlets and the wall switch then controlling the ceiling light. Sections or "chapters" of this video are listed below with the corresponding time stamp so you can jump around to fit your project needs.

Note: This is just for entertainment purposes only and you will need to check the electrical code in your area and also ensure all circuits are off during any of the work. Your safety is in your own hands.
