Installation Instructions for LED Recessed downlights

Planning Installation

The downlight installation requires planning to ensure timely, successful installation with minimal complications and down time.

Planning Suggestions

Consult an Electrical Inspector to review all wiring plans.
Create a Layout Plan drawing, per a Lighting Designer's or Architect's recommendation.
Consult FOBSUN Electronics Application Engineering Services as needed.


Make sure to turn off power at your circuit box before starting any electrical project.
Be certain that your existing circuit will be able to handle the new load of your LED downlights.

Helpful Tips

Some municipalities may require that you obtain a permit before performing this work.
You should have a licensed electrician inspect your work before you reestablish power.

Installation Steps

1. You should space your lights about 6-7 feet apart to get a good overall coverage in your room. Determine where the joists are in your room so that you can place your lights accordingly. Keep in mind that if you place all your lights between the same two joists, you will have less trouble running wire than if you place them between different joists. To make an easy installation, minimize the number of joists that you have to run wire through.
2. Before you start the construction portion of the project, cover or remove all furniture and cover the floor with a drop cloth, as you will make quite a dusty mess installing your recessed lights. You may also want to cover interior doors to contain your dust and open outside windows.
3. Shut the power off at the main service panel before doing any work on your electrical system.
4. Your next step is to remove and disconnect your existing fixture. Unscrew the wire connectors to release the fixture from the incoming wire. Be sure to test that the power is off with your electric tester light before handling the bare wires directly. The incoming wire (from the electrical box) is the one that will supply power to your new recessed lights.
5. You will need at least 7" to 8" above your ceiling with most recessed lighting cans. Drill a hole where you wish to install your lighting, and be sure that you have that much space with a wire coat hanger. Also be sure that you know where your joists are with a hanger and a stud finder. The housing for the lights will go between these joists.
6. Using the manufacturer's template, mark the openings and cut the openings with a drywall saw where you intend to install the lights. Take into account where your joists are so that you will not need to recut and patch incorrect cuts. Install the mounting hardware that includes the electric box for each light fixture.
7. If you have access to the ceiling joists in your room, you should use cans that mount directly to the joists for greater stability. In rooms with an existing ceiling, you will need to use the cans that attach directly to your drywall. Although not as sturdy as cans that attach to the joist, there is less cutting and mess involved, as you will not have to tear down your ceiling.
8. After you have cut all the holes in your drywall as necessary, you will need to drill holes in the joists to accommodate the wires that will run from light to light that are separated by joists. Make as few holes as possible while still reaching all the lights. Reach through the holes in the drywall and drill holes large enough to accommodate your wire. You should not cut a hole that is greater than 1/4 of the width of the joist.
9. Now run electrical cable from your old fixture's box to the closest new fixture opening. Run wire from opening to opening until all fixtures will have power. You will need to run the wire through the joists as necessary. You will need to have about 1-1/2' of extra wire dangling from each opening.
10. Using wire connectors, connect each can to the incoming and outgoing wires by connecting matching wires - red to red, black to black, and green to green.
11. Lift the can onto the drywall using the retaining hardware that came with your particular can.
12. Now, last but not least, install the trim pieces that you have selected.
13. Screw in your LED downlight, and turn back on your power and test your work.
