Fluorescent Fitting. How Long Has This Been Going On?

I was relamping some old high level 5 foot fluorescent fittings today. The Thorn Popular Pack type of old. They were fitted with Atlas tubes. So, I was wondering, what is the oldest working fluorescent fitting that you have come across with a heavy wound magnetic ballast and fluorescent starter unit?

    I have seen immediate post war fluorescent light fittings still in use fairly recently.

    5 foot, 80 watt lamps, bayonet cap lamps, choke tapped for different mains voltages. Separate starting transformer. These transformer start circuits wont work a modern lamp.


    I have seen fittings with no choke, a special filament lamp being wired in series with the tube. These special ballast lamps are no longer manufactured AFAIK.


    I also recall special coloured fluorescent lamps that were a different colour each end. Obtained by different phosphor coatings not by a colour filter. They came in three different colours. Pink/blue, pink/green, and blue/green. Popular for street lighting in seaside resorts.
