Circular Tubes in 535?

[Beta 5]

Did circular tubes ever exist in colour 35 halophosphor?
I've seen plenty of 22W 29-530 and a fair few 33-640 but never a 35-535. Similar for all the other wattages too, in addition to the usual range of triphosphor also including 835 despite having never seen a 535.

Bright Light Lamps made the 65/80W T12 circline in 535 but I can’t recall seeing such an offering from any other manufacturer.

Ah yes Bright Light Lamps always made some more uncommon sizes and colour combinations! I guess that Circline in general was too low a volume for them to offer the whole colour range though.
Although 535 was a bog standard colour seeing a circline in it would be quite special just because of the fact they never seem to be seen!

I would assume they existed, if only for the reason that circlines are a "home" / "fancy commercial" (for 50s...70s ?) lamp format in the 1st place

Over here warm color lamps were not common in any size, pretty much everything was 765 with many older lamps 640, so i would not have seen them around even if they existed in other places
