- Wraparound Fixtures: These fixtures are typically mounted directly to the ceiling and feature a wraparound lens that diffuses light evenly. They are popular in residential settings such as basements, garages, and kitchens due to their straightforward design and ease of installation.
- Strip Fixtures: Often used in both residential and industrial applications, strip fixtures are long, narrow fixtures that can be mounted individually or in continuous rows. They are ideal for providing task lighting in workspaces, garages, and under cabinets.
- Under-Cabinet Fixtures: Specifically designed for installation beneath cabinets, these fixtures offer focused lighting for tasks such as cooking and reading. They are compact and efficient, providing excellent illumination without overpowering the space.
- Circular Fixtures: Also known as circline fluorescent fixtures, these use circular fluorescent bulbs and are typically found in ceiling or wall-mounted applications. They offer a unique aesthetic and are commonly used in residential bathrooms and utility rooms.
Understanding the various types of fluorescent light fixtures can help you choose the most suitable replacement and ensure that the new installation meets your specific lighting needs.
10 Methods How to Replace Fluorescent Light Fixture
1. Gather Necessary Tools and Materials
Before starting the replacement process, gather all the necessary tools and materials. You will typically need:
- New fluorescent light fixture (or LED retrofit kit)
- Screwdriver (Phillips and flat-head)
- Wire cutters/strippers
- Voltage tester
- Electrical tape
- Wire nuts
- Ladder or step stool (if needed)
- Safety glasses
- Work gloves
Ensure that the power to the existing fixture is turned off at the circuit breaker panel before beginning any work. Safety should always be a priority when working with electrical fixtures.
2. Remove the Existing Fluorescent Light Fixture
Start by removing the existing fluorescent light fixture. Most fixtures are secured by screws or clips. Use a screwdriver to loosen and remove the screws holding the fixture to the ceiling or wall. Carefully lower the fixture to expose the wiring and set it aside. Be cautious as fluorescent fixtures can be bulky and fragile.
3. Disconnect the Electrical Wiring
Once the fixture is detached from the ceiling or wall, locate the electrical wiring connections. There will typically be three wires: black (hot), white (neutral), and sometimes green or bare copper (ground). Use a voltage tester to ensure the power is off before proceeding. Then, disconnect the wires by removing the wire nuts or screws that secure them. Untwist the wires and separate the fixture from the electrical box.
4. Prepare the New Fixture or Retrofit Kit
Prepare your new fluorescent light fixture or LED retrofit kit according to the manufacturer’s instructions. This may involve assembling parts, connecting wires, or adjusting the fixture’s length or configuration to fit your space. LED retrofit kits often come pre-assembled and are designed to fit into existing fluorescent fixtures, making installation straightforward.
5. Install the New Fixture or Retrofit Kit
Position the new fixture or retrofit kit over the electrical box in the ceiling or wall. Align the mounting holes with the screws or clips previously used to secure the old fixture. Use a screwdriver to secure the fixture in place, ensuring it is flush against the mounting surface. Follow the manufacturer’s instructions for any specific mounting or installation requirements.
6. Connect the Electrical Wiring
Connect the electrical wiring of the new fixture or retrofit kit to the existing wires in the electrical box. Match the black wire (hot) from the fixture to the black wire from the electrical box, the white wire (neutral) to the white wire, and the green or bare copper wire (ground) to the corresponding ground wire. Use wire nuts to secure the connections, twisting them clockwise until they are tight. Wrap electrical tape around the wire nuts for added security.
7. Secure and Adjust the Fixture
Once the wiring is securely connected, tuck the wires neatly into the electrical box. Ensure that no wires are pinched or exposed outside of the box. Gently push the excess wiring into the ceiling or wall cavity if necessary. Secure any additional mounting screws or clips to ensure the fixture is stable and level.
8. Test the New Fixture
Before fully securing the fixture, turn the power back on at the circuit breaker panel. Test the functionality of the new fluorescent light fixture or LED retrofit kit by flipping the light switch or using a remote control if applicable. Ensure that the fixture turns on and off correctly and that all bulbs or LED modules are functioning properly. If there are any issues, turn the power off again and double-check your wiring connections.
9. Adjust and Clean Up
Once you have confirmed the fixture is working correctly, make any final adjustments. Ensure the fixture is centered and level if applicable. Clean up any debris or packaging materials from the installation process. Dispose of old fluorescent tubes or components according to local regulations for recycling or disposal of hazardous materials.
10. Secure the Fixture and Finalize Installation
After testing and adjustments, secure the fixture permanently. Tighten any remaining screws or clips to ensure the fixture is firmly attached to the ceiling or wall. Double-check all wiring connections to ensure they are secure and properly insulated. Turn the power back on at the circuit breaker panel and verify once more that the fixture operates as expected.
