How to Install Ultra-Thin Exterior Lighting

Ask This Old House master electrician Scott Caron installs ultra-thin, LED lights on a garage to replace a broken floodlight.

Steps:

  1. Before doing any electrical work, ensure power is turned off at the breaker. Confirm the power is off using an electric tester.
  2. Remove the current light fixture and disconnect the wires.
  3. Measure and mark where each new light fixture will go, maintaining even spacing.
  4. Use a hole saw to drill openings for the new lights.
  5. Fish 14-2 electrical wire from the main power source to one fixture. Fish wire to any additional fixtures.
  6. Make the electrical connections to each junction box and tie the wires together using wire nuts.
  7. Clip each LED light into its hole.
  8. Replace the existing light switch with an astronomic timer switch that will automatically turn the lights on at dusk.
  9. Restore power at the breaker and test the lights and switch.
