A new benchmark for cheap tat ?

[Michael GilliganParticipant @michaelgilligan61133]

One of my ‘GLS’ LED light bulbs recently started to flicker at switch-on

… It’s done good service for three years so I don’t begrudge the £1 that it cost me.

What did infuriate me however was that the bayonet in the lamp-holder disintegrated as I was removing the bulb … The ‘female’ bayonet being made entirely from tatty grey plastic !

There is a certain expectation that low wattage lamps as in LED will not get as hot as an incandescent lamp. However even 5W downlights in an insulated ceiling will build up enough heat to destroy poorly designed LED lights. Did your “cheap tat” light have a C E mark as opposed to a CE mark?

As an aside, I replaced some GU10 50W incandescent flush mounted spotlights with 5W replacements last week. The base of one of the 50W lights I was removing separated from the glass part as I removed it, shoddy, it has only been in use for 24 years. I am keeping the 50W ones as standbys in case the LED ones do not last long.

Sorry Martin … we appear to be at cross-purposes

I was delighted by the performance of the LED bulb and would consider it excellent value for money.

… it was inappropriate quality of the lamp-holder that annoyed me.

The pendant fitting is, after all, typically regarded as a “fixture” in a house.

The old bakelite ones used to fail like that but they did sometimes have 150W lights hanging in them. It all comes down to heat even with LED lights.

Strange that there was barely any discolouration on the white plastic body of the bulb.

Was the socket previously home for a fluorescent? The UV might have killed it.

[Michael GilliganParticipant @michaelgilligan61133]

Not to my knowledge, Dave …

There was a rather fussy tungsten fitting [probably hard-wired]  there when we first viewed the house [3 years ago], but the seller took that with him.

I wasn’t interested at the time, but I suspect this lamp-holder was installed when he removed that.

As an aside, the threads on lamp holders do not seem to be standardised.

My wife fund raises for an animal refuge. She was given a couple of table lamps, which lacked shade rings.

One has been made, with an internal 28.5 x 1.25 thread. The other, now on the Round Tuit, has a rather skeletal  28 x 2 thread.
