Rebulbable lights last far longer, come in a huge range of

Lights with fixed LEDs last longer,

the life of one LED only. Duh.

with is ~10 years if they are only on for 12 hours a day.

Some don't even live in the same property for that long.

The reason they last longer is because they can be cooled
better than some random fitting retrofitted with a LED bulb.

No dennis. The reason they last less long is a) the
manufacturer couldn't care less as long as it makes a few
years

So don;t buy from a cheap manufacturer. The same goes for any
product.


b) since it's only on a small % of time they push the LEDs much
harder. BC/ES LEDs OTOH are rated at 15-25k hours

why would they need to push them harder ? Ah because they are
crap quality to start with ?



because it suits tabby's argument.

he ignores the often reported failures of LED bulbs due to over
heating of the PSU in the base.

Of course you could buy philips hue bulbs which will have a switch
mode supply in them but they are £20+. The cheap ones come with a
crappy capacitor dropper which wont last a year in an unventilated
lamp or even one that has the bulb hanging down. .

I see you're dodging reality again. A year is 8,760 hours. A 15k or
25k rating means the lamps last an average of 15 or 25k hours run
time. That there are infant failures on all LED lamps makes not one
whit of difference. Other than the relamping cost of £3 versus £70.

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.

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

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.

I use very long led strip lights now in the kitchen.
