Who makes lamps to be sold here in the USA?

Don't know about USA, but I use lamps made in the following countries:

Hungary - Osram
Poland - Osram as well as the Philips TL40W33RS lamps lighting my office
Germany - Osram again as well as NOS Siemens lamps circa 1936
USA - a few older GE lamps at one time
Czech Republic - Osram
Thailand - the pack of Philips lifemax TLD 36W/54 daylights next to me now
South Africa - very old Robertson lamps I have
Great Britain - GE 400W merc Iuse as room light
China - so many are made there now....

My favourite brands are Osram, Ge and Philips as you can see.

Update, just changed 3 F30T12 GE tubes, NOS that I forgot all about, mostly because I last changed them around 5 years ago. On 12 hours a day 7 days a week as shop display lights. When installed 14 years ago they used pink tubes, but after 1 year I got 24 of the GE tubes ( 4 boxes of 6) and am now down to last box. Nice tubes,  cool white made in USA and a lot better looking than other cool white brands. Also found little 6W made in Chicago, Ill in same box hidden at top of shelf.

Westinghouse made good lamps back when they were still in business, now I see cheap imitations of their lamps sold nowadays.
