How to wire outdoor led flood light?

September 27,2022

Installing exterior LED flood lights is a great way to add security, safety and nighttime curb appeal to your home. Whether you need extra light in dark corners of your yard, or around walkways or entrances, chooseProfessional Outdoor LED flood lightssupplierare a great choice to illuminate and accent your property.

Choose Floodlight Locations

Decide where you need more light at night. Lights installed near home entrances or garage doors are ideal, both for car and foot traffic. If you have a utility shed in a dark corner of your property, install a light there to deter any potential intruders looking for an opportunity.


Use a ladder to reach the location where you will install the floodlight (the fixture should be installed high—for example, near the roof—to provide effective coverage) and mark it with a piece of tape or a marker or pen.

Find Nearby Power Source

Locate a nearby power source—for example, an inside outlet or switch from which you can run wiring to the outside for the new light. Be sure the circuit you will tap into can handle the additional load from the new light. Turn off the circuit at the breaker box to help see what fixtures and switches are already on the circuit. The circuit load you use shouldn’t exceed 80 percent of the total load capacity. Total wattage in this case would be 2,400, with a safe wattage use of 1,920 watts. Add up the total wattage being used on the circuit to see if it can handle the extra output of the floodlight.


Prep the Fixture

Use an electric drill and hole saw to cut a hole on the exterior of your house in the location you chose for your floodlight. Remember, the higher the floodlight is placed, the more effective it will be. Make the hole large enough to feed electrical cable through it to the junction box from which you will be feeding power to the fixture. Fish the electrical cable through the exterior hole to the junction box so that you can make the connection, using a fish tape.

Helpful Tips

If you’re unsure of your electrical skills or your ability to fish the electrical cable through your walls, call in a professional for help.

Connect Power to the Fixture

Turn off power to the circuit at the home’s main electrical box. Verify that power is off using a high-voltage neon circuit tester in an outlet that is on the same circuit. If you’re unsure, you can also shut off power to the entire house by turning off the main circuit breaker

Safety Alerts!

Never trust an inoperable light switch as a sign that the circuit has been deactivated.

Make sure the circuit is truly “dead” before touching any wires or terminals. Check for current again with a voltage tester before continuing to work.

Test the Light/Motion Detector

Reactivate power to the circuit and step outside to make sure the light is on. If your floodlight has a motion-activated sensor, test that it is working as well. Remember to direct the floodlights toward the ground for optimum illumination.
