How to Install LED Disk Lights: Two Easy Methods

LED Disk Downlight Blog

In the realm of modern lighting solutions, innovation continues to shape the way we illuminate our spaces. Disk lights, a unique and versatile option, have emerged as a popular choice for both residential and commercial applications. In this guide, we dive into the world of disk lights, exploring their distinctive features, applications, installation process, and how they differ from traditional recessed LED lights.

What are Disk Lights?

Disk lights, also known as surface mount disk downlights, are lighting fixtures characterized by their sleek, low-profile design and surface-mounted installation. Unlike traditional recessed LED lights, which are installed within the ceiling, disk lights are affixed directly onto the ceiling surface, protruding slightly to provide illumination. This surface-mounting capability offers greater flexibility in installation, making disk lights ideal for spaces where recessed lighting may not be feasible or preferred.

Differences Between Recessed LED Kits and Disk Lights

One of the key distinctions between recessed LED kits and disk lights lies in their installation method and placement. While recessed LED kits are concealed within the ceiling, creating a seamless and flush appearance, disk lights are mounted directly onto the ceiling surface. This difference in installation style impacts factors such as space requirements, installation complexity, and aesthetic appeal.

Surface Mount vs. Flush Mount

Surface mounting refers to the installation of lighting fixtures directly onto the surface of a ceiling or wall, without the need for recessing. In contrast, flush mounting involves installing fixtures so that they are level or flush with the surrounding surface, creating a seamless integration with the ceiling or wall. Disk lights, being surface-mounted fixtures, offer a distinct visual aesthetic and can be easily installed in a variety of settings without the need for extensive modification to the ceiling structure.

How to Install LED Disk Lights Downlights

Tools and Materials Needed

Before installing your LED flush mount ceiling light, ensure you have the following tools and materials:


  • LED disk lights compatible with your installation type (E26 retrofit or junction box mount)
  • Screwdriver
  • Wire stripper
  • Electrical tape
  • Safety glasses
  • Ladder
  • Voltage tester

Safety Precautions

  • Turn off the power at the circuit breaker to avoid electrical shock.
  • Verify power is off using a voltage tester.
  • Wear safety glasses to protect your eyes.

Installation Method 1: E26 Retrofit Design

Step 1: Remove Existing Bulb and Trim

  • Remove the existing light bulb from the socket.
  • If there's a trim or ring, gently remove it by pulling it down and detaching it from the ceiling.

Step 2: Screw in the Adapter

  • Your LED disk light should come with an E26 screw-in adapter. Screw this adapter into the existing light bulb socket just as you would a regular bulb.

Step 3: Connect the LED Disk Light

  • Connect the LED disk light to the adapter. This usually involves plugging a small connector from the disk light into the adapter.
  • Once connected, gently push the LED disk light into place. Depending on the design, it may snap into place or require slight rotation to lock in.

Step 4: Test the Light

  • Restore power at the circuit breaker.
  • Turn on the light switch to ensure the LED disk light works properly.

Installation Method 2: Junction Box (3-inch or 4-inch)

Step 1: Prepare the Junction Box

  • If you’re replacing an old fixture, remove it and disconnect the wiring.
  • Ensure the junction box is securely fastened and suitable for the weight of the LED disk light.

Step 2: Connect the Wires

  • Your LED disk light will have two wires for power (typically black and white) and a ground wire (green or bare copper).
  • Using wire strippers, prepare the ends of the wires from both the LED light and the junction box (if not already done).
  • Connect the black wire (hot) from the LED light to the black wire from the junction box. Use a wire nut to secure them.
  • Repeat the process with the white wires (neutral) and then with the ground wires.
  • Wrap each connection with electrical tape for extra security.

Step 3: Attach the LED Disk Light

  • Place the LED disk light against the ceiling, ensuring the wires are neatly tucked into the junction box.
  • Secure the LED disk light to the junction box using the provided screws or mounting bracket. The method of attachment may vary slightly depending on the product.

Step 4: Test the Light

  • Turn the power back on at the circuit breaker.
  • Test the light to ensure it is working correctly.

Uses and Applications of LED Disk Lights

The versatility of LED disk lights makes them suitable for a wide range of applications, both indoors and outdoors. From residential kitchens and living rooms to commercial offices, retail spaces, and outdoor landscapes, disk lights can provide efficient and effective illumination wherever they are installed. Their low-profile design and adjustable color temperature options make them particularly well-suited for accent lighting, task lighting, and ambient lighting in diverse environments.

Tips for Purchasing LED Disk Lights

When selecting LED disk lights for your space, there are several key features to consider:

  • Color Temperature: Look for disk lights with selectable color temperature options, allowing you to customize the lighting to suit your preferences.
  • IP Rating: Ensure that the disk lights have a suitable IP rating for their intended environment, such as IP54 for damp locations.
  • Housing Material: Opt for disk lights constructed from durable materials like die-cast aluminum for long-lasting performance.
  • Certifications: Choose disk lights that are ETL and Energy Star certified, ensuring compliance with industry standards for quality and safety.
  • Dimmability: Select dimmable disk lights with a wide dimming range (5%-100%) for enhanced flexibility in lighting control.


Disk lights offer a versatile and stylish lighting solution for a wide range of indoor and outdoor applications. With their surface-mounting capability, adjustable color temperature options, and high-quality construction, LED disk lights provide efficient, effective, and aesthetically pleasing illumination wherever they are installed. Whether you're upgrading your home lighting or enhancing the ambiance of your commercial space, disk lights are a versatile and practical choice for illuminating any environment.
