You'll have to be more specific. What lamps were in use? Which
studio?

TC6 & 7 were equipped for NTSC 525/60 as well as PAL 625/50 when
they were first equipped for colour, or perhaps I should say color.
This facility was only used once and, as you not, standards
converters were used there after. What lanterns? The same as in use
in all the other colour studios at the time. The dual purpose
(fresnel/flood) - a BBC spec, but I can't remebember who made them.

Right. And you're saying the studios couldn't be run at 525/60 because
of strobing from the lights?


Strobing ? a 10Hz flicker yes.

So why don't they flicker when the studio is running at 625/50 - since
it's not locked to the mains frequency? The eye would see a flicker at
much lower speeds than 10 a second.
