Post the countries where you know certain types of bulbs are made and what type. Thus far I've encountered: Sylvania T8s made in Germany (early gen T-8 before Ecologic) Sylvania T8s made in Mexico Sylvania T8s made in USA Sylvania T8s now made in China??? Sylvania T12 Made in USA GE T8s Made somewhere in Europe, can't remember where.. will look again GE T8s Made in Canada Phillips made in??? I know Sylvania still makes many of their incandescent bulbs in America, and I believe so does GE? Thanks Ryan

Phillips made in Poland and Indonesia are what I buy. Reflectors are Polish and flourescent are Indonesian.
A few NOS are French made.

Hmm. I don't know if I've never seen a Sylvania T8 made in China. Sylvania is interesting because there have been two different companies operating under the brand since 1993. If you're in the U.S., any Sylvania lamps should be Osram Sylvania. I actually have a Havells-Sylvania circline that probably wasn't supposed to imported into the U.S. under the Sylvania name, but got through because it was included with a fixture.
Any idea which company produces the most bulbs in the U.S.? Not long ago, I would have guessed GE, but with their recent plant closures, I wonder if Sylvania now makes more bulbs here.

Yep Osram Sylvania makes most of their lamps in the USA. I can't think of any Sylvania fluorescent lamps made in China, save for the PLs and CFLs. Philips still makes fluorescent and HID here, and there are two small manufacturers of long life incandescents remaining here as well.

Thanks all. I am sure you just like me, prefer to support the companies in our home nation, when possible. Sounds like I have been doing well with the large Sylvania purchases. Just got a bunch of boxes of Sylvania T-8 3000k tubes to start using now that I've exhausted my surplus of mixed/matched Phillips 700 series fluorescent tubes. The color of the 3000k is so much nicer in most of the environments I install in and already I'm getting comments from folks who notice a difference. One of the office buildings I pass when I go into the office every now and then is a 6 story building, all with "daylight" tubes in it. It gives me a headache just looking into the building from the outside at night, not sure how the workers could stand that.

I've got two Sylvania Pentron 54W HO T5 lamps, one made in Germany and the other made in Italy. And, of course there's the Hamilton factory in the UK for Philips SOX lamps.

Bring SOX lamps back!!!
FYI, LED's are NOT the most efficient lighting technology available! Don't know how people keep coming to that conclusion!

Philips T8 fluorescent tubes from what I see are made in USA. The circle fluorescents are made in Thailand or Indonesia.
Most of the Sylvania incandescents are made in USA. Philips incandescent mostly made in Mexico. GE incamdescent appears to be Mexico or China. The GE rough service bulb is made in Hungary.

That is a pretty common issue with many fluorescent fixtures, the ballast causes interference on the AM dial I've changed different ballast brands in the past and that has helped the issues somewhat.

When I changed the bulb ( F8T5 ) the noise went away. The ballast is INLINE to the power cord.....

Different lamp properties (vary with manufacturer, batch, lamp life...) cause the ballast to run at different frequency

I tried this bulb in 3 different fixtures and the same result. I will try it in the solid state one.

No. It is the fault of the lamp, but I want to see if the solid state ballast that runs 2 lamps will be HF enough to not cause that noise.
