What happens in this clip
With the holes cut, it's time to run the electrical wiring. This often involves feeding NM-B (Romex) cable through the attic space above the ceiling or, if no attic access, using a fish tape to pull wires between the ceiling holes. Ensure there is enough slack at each hole to make the electrical connections later. All wiring should follow local electrical codes. The wires should be pulled through the holes without excessive tension or damage.
Goal: Feed new electrical cables through the ceiling joists and holes to provide power to each recessed light fixture.

About the full video
This video demonstrates the installation of sleek, modern LED recessed lighting in a garage ceiling, along with some general electrical wiring for wall outlets. The process covers planning light placement, cutting ceiling holes, running new electrical wiring, connecting fixtures, and testing the final setup.
Step 3 of 7: Run Electrical Wire
Determine the most efficient path to run the electrical cable (e.g., Romex) from the power source (typically a junction box or switch) to each of the cut openings. This may involve running wire through wall cavities, attics, or crawl spaces. Secure the cable using appropriate clips or staples to the framing members, ensuring it is not pinched or damaged. Leave enough slack at each opening to make the electrical connections.
