Sylvania 4' 40W Soft White

Sylvania 4' 40W Soft White

Click to view full size image

These American-style tubes are never normally seen in the UK. Soft White is closest to our Deluxe Natural. They use the old-fashioned phosphor with the amazing red persistence (afterglow) after switch-off that you don't get with the later halophosphates. I managed to get 12 of these in pristine condition back in the 80s or 90s (I forget which). I have no idea how old they are.

Those are strange lamps! Are they actually USA-made? The etch and endcaps are unlike any other USA Sylvania lamps I've seen.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

Really odd that there is no country of manufacture on these lamps! Absolutely top find one I have never seen before in my life. Better made than the current Sylvania T12s which are just a joke really

Voted to leave the EU and proud! 👉🏻🇪🇺🇬🇧

Probably not USA made but USA style (specs, packaging, description)? I can't imagine why.

Cathode shields promote boring fluorescents.

Looks like a thorn made one maybe for the American market as the American guys call switchstart "preheat" over there.

I'm also not sure why it doesn't say "preheat-rapid start". I know that in North America, there were separate lamps for preheat and rapid start at first, but this one looks to be newer than that because of the FxxTxx order code.

Your tube is Atlas-made in the UK, March 1972 I believe. The other option is March 1967 which seems rather early, and I have ruled out the third option of March 1977 as Endura was making the tubes then, not Atlas.

Sylvania made fluorescent lamps in France back then, but they imported certain types from the USA also.

May all the great lighting technologies have their place in history.
