Installation Instructions
Follow these steps to install your Kichler Horizon LED Downlight. For visual guidance, refer to the installation video below. While the video may show a general semi-flush/flush mount, the core electrical and mounting principles apply.
Step 1: Disconnect Power
Before starting any electrical work, locate your main electrical panel and turn off the power to the circuit where you will be installing the downlight. Use a voltage tester to confirm that the power is off at the junction box.

Step 2: Prepare the Junction Box
If replacing an existing fixture, carefully remove it. Ensure the wires coming from the ceiling are black (hot), white (neutral), and bare copper or green (ground). If the wiring colors differ, consult a certified electrician.
Step 3: Attach the Mounting Bracket
Secure the provided mounting bracket to the junction box using the screws included in the hardware kit. Ensure the bracket is firmly attached and stable.
Step 4: Make Electrical Connections
Connect the fixture's wires to the supply wires from the junction box:
- Connect the bare copper or green ground wire from the fixture to the bare copper or green ground wire from the junction box using a wire nut.
- Connect the white (neutral) wire from the fixture to the white (neutral) wire from the junction box using a wire nut.
- Connect the black (hot) wire from the fixture to the black (hot) wire from the junction box using a wire nut.
Carefully tuck all connected wires into the junction box, ensuring no wires are pinched.
