I'm wondering when exactly other types of control gear started to appear for fluorescent tubes other than a series choke and starter switch?
Quickstart seems to have been around for a long time, more frequently referred to as 'instant start' in older catalogues, I'm not sure when it was introduced though?
The same goes for Semi-Resonant Start, I've heard this was Thorn's invention but I'm not sure when exactly it was invented? Seems to be late 60s or early 70s?
Topics relating to lighting control gear, including magnetic & high frequency ballast and ancilliary devices such as starters, ignitors and switchgear.

Atlas/Thorn invented 'Quickstart' way back in 1947 which soon
led on to dimmable fluorescents. The others soon cottoned on with names such as Rapid start (US)' instant start'(Osram/GEC) and 'snapstart' (Crompton). I reckon SRS, also pioneered by Thorn, was mid to late 60s.
I LOVE LAMP!
