There are some reasons. Like where the 'bulb' is visible and looks better
than the LED equivalent. And the actual light quality from a LED still
doesn't match that of halogen. Although it may get there eventually.

Philips have removed the last real use for filaments, in chandeliers, with their, I forget the name, but a plastic crown that creates a filament-like appearance.

The only use left for filaments is in ovens & heaters. And I guess historic fittings that no LED or CFL fits.

Yes, lava lamps. Didn't realise there were still sausage electrocuters in use.

And dial lamps in old gear. They can't always be replaced with LEDs.
They also work as short current limiters.

Both CFL and LED have attempted to look the same. Perhaps that's why they
haven't succeeded for everyone.

If all you want is light to see your way by, they're likely OK. Some may
have extra requirements.

I'd now put an LED.

The trouble is that G9 LEDs have a much lower lumen output than halogens
as they simply overheat in unventilated G9 fittings. In fact, it can be
difficult to fit some of the higher-powered G9 bulbs in a fitting
designed for a halogen bulb as they are often too wide at the base.

Four years ago I replaced 8 x 42w G9 halogens with what were advertised
as 7w LEDs (450 lumen IIRC). I doubt they were much over 200 lumens,
and the first one started flickering a couple of months ago. It finally
failed last week.

But as LEDs are used more and more, will the factories to produce
tungsten filament bulbs remain?

I can see things like new ovens beginning to use LEDs and light-pipes or
similar so that they can be installed in a cool spot. Where the heat of
the bulb is required, LEDs and separate heating resistors may become the
norm.

Direct replacements for lamps in existing equipment may become difficult
to obtain.

I wonder how long fluorescent tubes will be available - many outlets
have stopped selling the fittings already, switching to LED versions and
many, but not all, existing fittings can be converted.

I've actually got very few 'bog standard' 'bulbs' here. And that's often
where there isn't a single LED available that produces the same output.

My Liebherr fridge does the same.

The light is energised via a resistor in the electromachanical

That must be several years old. My Liebherr LED fridge light takes a
few seconds to achieve full brightness after the door opens (why? is it
for night raiders who can't stand a sudden blinding light?!). I also
doubt it has an electromechanical thermostat, as there isn't much need
for one when it can have an internet connection. Not that I'd use it.

No flicker, instant light, and very bright etc.

I can't find a Smart Golf ball LED or even dimmable bulb equivalent to 40W.

Possibly. The fittings in my garage are at least 20 years old, probably
older. There were in place when we bought the house and the conventional
tube life is terrible- so much so that I started to wonder if they were
T12 fittings and I was using T8 tubes.

I've only replaced one with an LED tube so far but the others will be
replaced as they fail- I don't see the point in dumping working tubes.

I'll do the same in my electronics workshop. There the fittings were new
about 18 years back. Those tubes have lasted well.

There are a few reasons:

You can't get adequate light output from a single lamp

They need to operate in a high temperature environment where the
electronics of a LED lamp would fail.

Where full spectrum colour is absolutely required (all the current
"white" LEDs are AFAIAA basically generating light using fluorescent
phosphors being excited by blue LEDs - and so produce white light with a
discontinuous spectra in much the same way as a CFL and other discharge
lighting)

In very low usage scenarios, where its not worth the cost of a more
expensive lamp. (I have a conventional bulb in my shed - it probably
gets turned on for less than an hour a year).

Where you have a long wire run with some inductive coupling that causes
LED lamps to flash when turned off.

Where you need some additional minimum load on a dimmer.

Where you need a full and very wide range of dimming, and want to retain
the natural shift in colour temperature that you get with filament lamps.

In applications that flash lamps - some LEDs don't decay in output as
quickly due to their capacitive droppers/PSUs.

You need a form factor not available in LED

You don't like the light quality / colour

Would think the difference in purchase price is WAY outweighed by
running and replacement savings.

In the majority of cases.

There are a few reasons:

You can't get adequate light output from a single lamp

That is the only one that I think is still a problem.
No good priced LED equivalents for 150W, 200W and 250W bulbs.

Some corn on cob sorts are available but still expensive as yet.

electronics of a LED lamp would fail.

That is certainly an issue in ovens and some closed glass shades.

They are very much better than fluorescents but even so you couldn't do
satisfactory daylight colour matching under one.

In very low usage scenarios, where its not worth the cost of a more
expensive lamp. (I have a conventional bulb in my shed - it probably
gets turned on for less than an hour a year).

My remaining filament bulbs are in the seldom used light fittings. It
naturally happens that way if you replace on failure.

Where you have a long wire run with some inductive coupling that causes
LED lamps to flash when turned off.

Where you need some additional minimum load on a dimmer.

That is another practical one where having one filament bulb to match
the dimmers operating load is necessary. Incidentally I am not all that
impressed with supposedly dimmable lights and controllers - a friend
with some high end ones is on his umpteenth free replacement of the
dimmer which seems to expire with monotonous regularity.

Where you need a full and very wide range of dimming, and want to retain
the natural shift in colour temperature that you get with filament lamps.

Some of the variable colour LEDs could be programmed to do that.

In applications that flash lamps - some LEDs don't decay in output as
quickly due to their capacitive droppers/PSUs.

They have come on a long way. Warm white is now a pretty good match for
filament bulbs.

And by some margin. Trouble is people tend to notice the shelf price and
then ignore the longer term lifetime running costs.

Though I have to admit that while I'd rarely leave an incandescent lamp
on, I will do so more often with an Ellie D.

i have some 70W panels like bigclive tested and they are extremely bright.


much brighter than a 250w bulb.

odd shape though and only 12V.
