AB is estimated to be around 4500K

Atlas:
Warmwhite is 3000k
4200K self explanatory
Natural looks like 3500K

Does anyone know what those series of dots near the atlas logo mean? Some form of date code?

They are indeed part of the date code.
Im afraid I do not know the coding. but at a guess these would be mid 1970's tubes.

Yes they're the date code, but I don't recall offhand what they mean. I think James has some info on Lamptech.

It'll be great to find out what age they are. It seems these Atlas tubes are a long way from home in GT Britain!

An elderly lady was selling them. I guess someone close to them was a light bulb salesman as these came in a brown lether style case.

I went ahead and put my daylight Durotest F20 lamp in with these. The long life lamps appear to be made by Durotest. Etch material, end caps and filament structure is the same between them

That's pretty awesome because from what I know of Durotest lamps, they seem to last a very, very long time
