Can you explain to the likes of me how a fluorescent tube with
separate control gear is a CFL?


The C stands for compact. The tube is compact - in comparison with a 4ft
batten fitting.

There were smaller than 4ft tubes around before the 2D. Surely what most
understand as a CFL is a complete unit which can replace a tungsten bulb?
Of course it would have made far more sense to stay with the 2D principle
- as it would with LEDs. A separate PS.
