I'm curious. "Low energy" bulbs are very much in the news - but how
much extra energy is expended in their manufacture compared to a
standard incandescent? I assume it's more - so is there a real net
/overall/ saving over the bulb life? If so, how much?

Sounds as though you're snatching at a straw as a reason for not using
them

Not in the least - I've started replacing them as they go, including the
6x60W R60 spots in the kitchen: the 15W non-spot replacements seem to
light the place just as well. Shame about the dimmers in other rooms
though: are there dimmable low-power lights around?

I really did want to know about the energy economics, as these are being
pushed as "CO2-friendly". It's obviously not a direct relation to
running power. Someone, somewhere, surely has done the sums. Or not??


They have done them, but they aren't telling you the results.

Because they are laughable.
