8' weren't 70w last time I checked.

Oops, that should have been 100W.

This is a strange lamp in the UK. It was the first retrofit energy saving tube, introduced by Thorn Lighting around 1978, replacing the 125W 8' halophosphate tube on switchstart gear. It was not until the follow-on energy saving tubes that they thought of dropping from T12 (1.5" diam) to T8 (1" diam), so this tube was an anomoly at being a T12 energy saving retrofit.

Other countries introduced the retrofit energy saving tubes slightly after the UK, and made the 8' tube a T8 like all the other retrofit energy saving tubes, but it remained a T12 in the UK. Having said that, 8' tubes only really worked on switchstart gear in 240V countries, and were not as common as the 6' tubes anyway.

8' were hugely common, 5' too, 6' not as much.
