I wonder if the guy even knows that the mercury, as small as the amount is, sticks to the phosphor and glass.

Correct, the machinery, tooling, and even the documentation and institutional knowledge associated with making this stuff probably all got tossed, scrapped, when the plants were closed and the employees left/retired. At best the equipment and tooling might have gotten transferred to other plants in the world that still make this stuff. I think Signify might have done that when they transferred fluorescent production to India. You might be able to restart simpler lamps such as incandescent, fluorescent but even then initial quality would suffer...think about how modern Polaroid film compares in quality compared to vintage Polaroid film, or even Fuji Instax for that matter.

More complicated lamps such as HID, especially ones with a PCA arctube and SOX would probably be too hard to restart production...worst case you might have to redo the decades of work done to optimize the process.

The same applies for the luminaires as well, the tooling for making housings, reflectors and especially the refractors is probably long gone as well. The manufacture of the refractors was complicated enough that most manufacturers contracted it out to companies specialized in glassware such as Holophane, Corning, and Kopp Glass. Fluorescent luminaires are a bit easier to restart production, you can make simple fixtures from a sheet metal cutting laser and a bending brake...even fixtures like louvers. 

 The listed colored lenses are interesting !

 They can "unban" whatever they like , doesn't mean manufacturers are gonna restart production . Most of the equipment for making that stuff has been long ago scrapped .  I like my old , non computerised cars without all of the "technology gadgets" . I'll pretty much guarantee non will ever be built again in mass quantities .

Some of their products seem to be fairly unique. I have a Satco 200w equivalent LED filament and I don't think I've seen a LED filament with such a output from the other brands.

Over here the smaller Home Hardware stores sell some Satco products but they're mostly common in electrical and lighting supply shops.

I think the F-Series was available for special order until 2019/2020 and into the Signify era. The last spec sheet for it has Signify branding and is still online and has a copyright date of 2019 on the last page. Interesting a 1500w MH model was made as well. Must have been bright.

Now, I think the smaller Wide-Lite Jr. Model which was based off the F-Series was probably discontinued in the 1970s before the HPS era, all examples I've seen online were 100-250w MV.

Yeah. I'm simply lucky the lamp was in its tight-fitting sleeve!

 The eBay ones are about 5 hours drive from me . If I really wanted to get one or more , I'd be tempted to go pick them up in person.

 I know the F-series was made into the 2000's .

There is a man near me who has 4 cases of Industrial Gold F40T12s.

Last time I negotiated a price of $100 for one case. Anyone interested?
I am willing to sell one tube at a time if there is enough interest.
