Cheap Halogens Occasionally Flickering

[lumenmachine]

Hello,

Had a call-out today for a lady who was concerned about 'flashing' lights throughout her house. The 'flashing' happens about once every 10 minutes, and the lamp essentially goes off for a split second. The issue happens across both of the lighting circuits. I've checked at the board and within the lighting JBs in the attic for loose connections but everything is nice and tight. The only thing I can think of is that the cheap halogen GLS lamps in use are causing this to happen, although I'm having trouble thinking of a reason why they would do this (if they even are).

Any thoughts appreciated!

Replace a lamp with a decent brand .................. did you check the incoming tails at the CU and the meter and the head?

Is there sizzling or crackling from the DNO head?

Checked the lot, I reckon it's the lamps and I'm over-thinking it. The 'flashing' happens independently; i.e. when the lounge light 'flashes' the kitchen doesn't etc.

Tell her all her neighbours have the "expensive" ones.

Are they leds

No, just the Halogen GLS lamps you get instead of Filament lamps nowadays.

Did you check ALL the CU connections? including checking the buzz bars are the correct side of the clamps

Have you seen it happen?

Yes, I was really hoping it was 'all in her head'

So its all rooms, both circuits, and you say ALL the connections are tight ...............

Outwith the property then? If that were the case wouldn't the lights 'flash' in sync?

If they have table lamps do they dip as well?

 

[Octopus]

Or your client has somebody using a welder in the garage ..........

I thought it might be to do with a load somewhere else too, but the 'flashing' occurred with just the lighting circuits energised. RE the table lamps, no - only the ceiling lights which had the Halogen GLS lamps in them.

In parts of Southampton the supply sometimes 'dips' when it's fed from different networks or something; apparently when the H&S manager is sitting at home and the lights dip he knows he's going to get a call from the factory because certain machines have stopped.
