Getting a bit tired of CFL bulbs that take up to a minute to warm up
too 100% brightness, so can anyone recommend any 'instant on' 60 Watt
(13 Watt CFL?) equivalent bulbs please?


There aren't any, sorry.

Trouble is, the run-up time is necessary for the high efficiency.
For fittings I make myself, the 2D compact fluorescents are about
the best in this respect, but that's also because they are slightly
less efficient.

They are better than they were in the dear old days but the best of
the current (No pun intended) crop are still about 30% - 50% down at
1 minute, and another 30% down after 12 month's service.(All except
"Dynamo" Hansen's, they positively coruscate within seconds of being
energised).

IMV Feit lamps from Costco (& others) are the3 best of a bad bunch

Agreed. They are the only CFLs I've seen which actually have the
correct filament equivalency printed on them (with 23W = 100W).
They also seem to last very well, including in enclosed (hot)
fittings. The 23W CFL lamps are bigger than 100W lamps, but are
probably the shortest 23W CFL you'll find, and fit in more
existing fittings than any other make I've found.
