tungsten is deposited on the quartz and short of heating the quarts to
white hot (above poster's remarks) the tungsten is going to STAY on the
quartz, not recoating on the filament.

** That is merely one person's opinion, not backed up with evidence.

Wiki says differently :

https://en.wikipedia.org/wiki/Halogen_lamp#Effect_of_voltage_on_performance

Stage lighting uses dimming all the time with halogen lamps and there is
no blackening or short life experienced - the lamps run much longer as
expected.

The claim that the "halogen cycle" puts metal back on the filament is
true but it does not deposit it back where it came from so has little
effect on lamp life.

Most halogen lamps are low voltage or high powered - so in both cases the
filaments are thicker than typical non halogen examples.

Having a thick filament makes a halogen lamp last longer.

Well, I must confess I've never studied halogen bulbs on dimmers but
reading Lutron's site does not give any concerns from them about halogens
on dimmers in household use:

It seems fairly obvious that a dimmed filament doesn't gas off much
tungsten.

Ordinary bulbs above a certain rating are banned and have been replaced by
halogen capsules enclosed in a regular globe envelope.

So far; I've not seen any dimmable CFLs on the shelves and LED bulbs are
probably more tricky. The packaged halogen capsules are the easy way out if
you want a dimmer.

They exist, our local Home Depot stocks them. Personally, I do not use them. If I need dimming, I use an LED.

Don't feel bad. When approached by an aggressive panhandler, I take this approach, 100% of the time:

You empty your pockets (I get to search), and I will empty mine (you get to search). Whatever we find, we split it right down the middle.

In well over 100 offers of this sort, I have never once had a taker.

** Dimmable CFLs require a special dimmer, not the standard triac kind.

LED lamps have the same issue, most of them are "non-dimmable" and the rest need a similar, special dimmer.

OTOH, if you have a spare Variac lying around, it will dim most CFLs rather well and LEDs not so well.

Those photos only prove you don't know what you're looking at. Those filaments have not nearly enough support to render those halogen lamps as sturdy as standard incandescents. Filaments that run that hot need more support per given length.

General Electric says this:

"Unlike incandescent rough service or vibration service lamps, Halogen and HIR lamps are not equipped with filament supports because they would result in the de-rating of the life and lumens, and thusly defeat the purpose of providing extremely long life, energy savings and high lumen output. These features differentiate Halogen and HIR lamps from similar incandescent counterparts."

Are you that delusional where you think anybody reading this NG would possibly agree with you Phil?

I would suggest you take that toaster you're rebuilding and modifying and take it in the bathtub with you (plugged in), but since your trailer is so roach infested I doubt you even know what a bathtub is.

Halogen tube lamps have sufficient internal supports to allow them to be used in portable work lights and similar jobs.

The problem with Phil is not that he rants and raves like a lunatic. The
problem is that people not only read his posts, they take them seriously as
if they *weren't* written by a deranged sociopath and respond! The
resulting conversations are *NEVER* productive resulting in a tirade of
insults and imbecilic retorts that demonstrate only the extent of his mental
illness. The conversations rage on with no useful content until everyone
finally tires of the insanity of it all and gives up the attempts at
rational discourse. Some people take longer than others.

Anyone who ever tried to use halogen lamps in portable clamp lights know they will be lucky to survive one minor bump, whereas even conventional incandescent lamps will survive several, and rough service incandescent lamps are extraordinarily tough.

them. If I need dimming, I use an LED.

Some LED bulbs are switch mode, usually flyback AFAICT. They are pretty much
the same as CFLs on a triac dimmer.

Most cheaper LED bulbs are wattless-dropper - I haven't bothered trying any
on a dimmer.

I've seen data sheets for PFC front end CFL and LED driver chips - but no
products on the shelves so far.

http://creebulb.com/bulbfinder

We use Cree lamps where we need dimming, and in general if replacements. We still have some few legacy LED lamps in place (stuff that came-with other stuff), but we do not intend to dim those.

NOTE: some cheap LED lamps are very noisy in the RF range. VERY noisy, approaching that of an unshielded ignition transformer (oil burner).

Okay, that's two that think they're right and General Electric is wrong. Not sure if that constitutes a consensus or not...

When dealing with closely held beliefs, revealed religion and pronouncements from burning bushes, only war will determine what is 'truth' - and only insofar as the winner writes the history books.

Keep in mind the 'simple truth' of Evolution:

In the United States:

19% believe in Evolution.
34% believe in pure creationism.
25% believe in 'directed evolution'.
The rest have no opinion.

And the US is by no means any different than the rest of the world in its beliefs.

So, something as esoteric as lamp filaments... you get the picture.

CR supplies used in some LEDs burn up on dimmers or MSW inverters. The voltage steps cause current pulses that increase resistor P_diss massively. They dim perfectly on variacs - but probably no-one uses variac dimmers now.

I suppose in principle a mosfet dimmer could switch off & on at the same voltage each side of the peak, and thus work ok with CR PSU LEDs, but I've not heard of such dimmers - not been looking for any dimmers for years though.
