Just as well they come with 3 - 5 year warranties then...

whatever use is that? I expect light fittings to last decades, and mine do.

Most decorate more than once every couple of decades and usually lighting styles and their fixtures change.

funny how that works. People buy junk, get fed up with it after 10 years and replace it with more junk. Rinse & repeat.

Yes they do that is how most people live.

While those that know what they're doing buy something satisfactory & keep it for life.

No they don't well perhaps royalty, stately homes might do.
do you really think people take their light switches with them when they move.

doubt it, but what has that to do with luminaire life expectancy?

Do you also buy a car for life the best car you can possibley afford and keep it for 50+ years ?

Very few do. Those that do end up with a valuable stylish car.


Do most only buy one house and live in it forever ?

and that has what to do with the life expectancy of luminaires?

And no surprise, in time it becomes the most desirable lighting around. Some of course short circuit that process & buy good very old fittings.

and most don't.

we know this. don't we?

Most also have to upgrade their electrics, not everyone has bought the best quality bulb and still has that running on DC for the last 50+ years.

and that has what to do with the life expectancy of luminaires?

Some of us have even replpaced our underwear in the last decade destite perhaps buying into armarni boxers.

what has the life of short lived goods got to do with the life expectancy of luminaires?

Not everyone is fooled into paying £1000 for a pair of shoe guarrenteed for life.

and that has what to do with the life expectancy of luminaires?

It'd be nice if they did last 100+ years.

they do. Assuming you don't buy idiot designs.

I bet they buy 100 year old cars too, and have a coal shed to suply their central heating.

who?
The house we put 1930s lighting in has either a century old car nor coal heating.


Even here at work where the lab is getting a serious makeover there's no plans to keep the 1990s light fitting (tubes) , just how many here use floruescant tubes in the kitchen now, most places I see now have downlighters which I don;t really like.

Lab lighting is very different to domestic

So how come LED's bulbs in the home are so popular, when gas lighting was fine 100 years ago.

can you not work that out yourself?
Gas lighting was never fine anyway.
