NM,

Thanks for the offer. But I do need a G50.

A G40 is a 5" diameter globe with a standard screw base. I could use a
plain 150w bulb, but it would not be as attactive. This is an tiffany-shade
type ceiling swag over the kitchen table.

Most light bulbs hum loudly when dimmed via a dimmer switch.

That's not been my experience.

A few are ok,
because they contain extra filament supports at critical positions.

I only have three dimmers for lights, but I've never had a lightbulb
hum because of one. Until a couple weeks ago, I was using a 150 watt
bulb in a desk lamp with a built-in dimmer right next to me.
Unfortunately, I knocked the lamp off the table and broke the bulb so
I don't have it, but I think it was the standard GE 150 watt bulb they
sell in supermarkets.

In the dining room I also have a 150 with a dimmer, and I'll check the
brand if you want me too. I only have to take off the cover. It's
probably not G-40 since I've never heard of that, so let me know if
you want me to check.

Otherwise, I'd say just try a different brand.

My hanging (swag) kitchen tiffany-style light takes a G40-150w bulb. It
hums badly when dimmed.

(1) Is there a brand of G40-150 bulb that does not hum when dimmed?
(2) Alternatively, is there a small, in-line filter available, or a
filtered, table-top dimmer switch, that would create a smoother
short-duty-cycle output than the intermittent, alternating square-wave
created by a typical dimmer switch? Would that be safe for a household
lamp application? Would that eliminate the audible humming?
