Well, I actually did miss the point, as you suggested, and
for several reasons. One is the way I handle messages.   I don't
always pay 100% attention, since there are so many
messages to read.  Another is that I generally read all
the messages in a thread before I write a reply.  In this
case I knew that somewhere, someone had done some
actual measurements but I didn't remember who. And
in my haste to trim the quoted part I didn't notice that
it was you.

On the other hand, what you reported was about the
way the filament cooled.  My question was about how
it heated.  They're related but they're not the same.
Also we both seem to think you get a half-cycle for
cooling.  I think for turn-on-at-zero you get a
quarter cycle the first time.
Further, if we look at what you said here,

>describes that I observed a *significant* change in the

and compare to the actual quote,

>With a diode in series one can actually see a distortion in

I know it could be splitting hairs, but one implies "Yeah,
you can see it" while the other implies "Wow! It's obvious!"
It just didn't sound like that big a difference to me.
Remember people are claiming a 60W bulb eats 1KW on the
first cycle...

I wasn't questioning your results and I don't question
that your bulbs are lasting longer.   But I was looking
for some evidence about the turn-on.  If you were
able to measure the current you should be able to
see the large inrush current when it's turned on,
and tell us some interesting things about that.

Still wondering,

Barry
