Need Help On My Living Hall Lighting.

[cyliyu 1]

I have the lighting as per the photos.

When I switch on, it keeps flicking and cracking noise can be heard, sometime it only happen after 30 sec when switch on.

I have replaced all the 8 bulbs and the switch but still same.

anyone got any ideas what could be the possible causes or any electrician to recommend?

How can I remove the fixture (8 bulbs attached to) to check on the wiring?

The flickering and cracking sound is probably due to poor/loose connection which is causing arcing.

Did you notice which bulb or bulbs were flickering or it occurs randomly to all the bulbs?

What is the wattage rating of each of the bulb?

Does the switch control only this light or the switch controls more than one light.

Do you use any dimmers for this light?

Whatever you do, please be careful not to touch any metal part of the fixture.

Can be easy seen, i even remove 7 bulbs and switch on with only 1 bulb, flick (random location) flicking and noise still there.

What is the wattage rating of each of the bulb?

8W per bulb.

Does the switch control only this light or the switch controls more than one light.

Yes, this is a 3 gang 1 way switch, one switch control only one lighting. the other 2 to the false ceiling no issues.

Do you use any dimmers for this light?

No

I also suspecting it could be due to lose wiring or contact issues but not sure how to dismantle the fixture - the one holding the 8 bulbs

From the picture shown, my guess is that you have to unscrew the round cover just below the ceiling. That will probably show all the mounting screws to the ceiling and the wiring connections to the fixture.

If you are trying to remove the casing for the bulb holders, unless you can see screws, it could be glued or snap fit, making removal a hit or miss affair.

You could also try to turn the vertical bars or round plate to see if they move.

Whatever you do, do ensure to switch off the circuit breaker to this circuit or turn off all breakers.

Hi All,

Problem solved.

Just to share, it was due to the burnt wire from the lighting.

Thanks all for your help.
