I suggest you learn some basic physics so you can ignore them.

Thanks for pointing out my mistake. I was told that by an electrician
back in the 70's and never felt the need to question it. You could try
enlightening me yourself though, instead of being patronising - how DO you
work out how much energy a fluorescent fitting uses during start up? It
seems to me quite possible, based upon my obviously extremely limited
knowledge in these things, that an incandescent lamp turned on for a brief
look in a cupboard could conceivably use less energy than a fl lamp.

Is 45 minutes a brief look?

Yes it is better to use incandesent lamps if you only use them for a minute
or two.
Not because they save power but because you don't have to wait for them to
warm up.

You shouldn't really believe everything electricians tell you.
Generaly they are no cleverer than anyone else, they just know how to wire
some electrical circuits.
They seldom know how the things actually work.
