Square ceiling lights provide even illumination and suit living rooms, bedrooms, and offices. Many modern LED bulkhead lights also use a square or near-square design. Following the correct steps keeps the installation safe and protects both the fixture and the ceiling.
Installation steps
- Mark the position
Use a measuring tape and pencil to mark the center and the four fixing points on the ceiling. Avoid pipes, beams, and decorations. Check that the ceiling material (concrete or plasterboard) can support the weight.
2. Drill the holes
Drill holes that match the expansion screws in both diameter and depth. For hollow plasterboard, use suitable anchors or locate solid support points.
3. Fix the mounting plate
Align the base plate with the holes and secure it firmly with expansion or self-tapping screws. The plate must sit flush and stable against the ceiling.
4. Connect the wires
Switch off the main power and verify with a voltage tester. Connect live (L), neutral (N), and earth (PE) wires correctly. Secure the joints with terminals and wrap them with insulating tape.
5. Attach the light body and cover
Clip or screw the light body onto the mounting plate. Then align and gently secure the cover. Match the LED power rating to avoid overload.
Removal steps
1. Cut the power
Always switch off the main power and confirm the fixture is dead with a voltage tester.
2. Remove the cover
Release the clips or unscrew the cover carefully to avoid cracking plastic or glass.
3. Detach the light body
Unscrew or unclip the body and keep small parts safe.
4. Take down the mounting plate
Remove the expansion screws. If they are rusted, apply a penetrating spray first. Pull the plate gently to protect the ceiling surface.
5. Handle the wires
Wrap exposed ends with insulating tape or label the live and neutral wires for easy reinstallation later.
Key points to remember
- Work only with the power off and never with wet hands.
- Do not overtighten screws, as this can crack the ceiling.
- Support the fixture during removal to prevent it from falling.
- For heavier lights (over 5 kg), add extra reinforcement.
- In humid areas, an IP65 bulkhead light offers better protection while following the same installation logic.
These steps allow most square ceiling lights and LED bulkhead lights to be installed or removed safely and cleanly.
