Of course Harry - an "intellectual interlude" on my part!

We use for 60W R80s in the kitchen and as I say, they used to last just a
few months. I bought a pack of ten Scr*wfix long-life ones, which they
claim to have an average life of 3,500 Hrs. (Price, œ7.79 for ten - 78p
each, less than five years ago). Haven't had one fail yet in about 2 yrs.
Their latest catalogue does list a low energy type R80 11W but they're not
cheap - œ7.57 each, average life 3,000 hrs, which would be about 2 - 3
yrs.
Depending on the type, SF's low energy bulbs have a stated average life of
8,000 - 10,000 hrs, some up to 15,000 hrs. Prices aren't the cheapest -
from about œ2.00 upwards.
All of these bulbs are very much more expensive than tungsten filament
bulbs, which either bayonet cap or ES from 60W to 100W, with an average
life of 1,000 hrs only cost œ1.67 for ten - less that the price of a cup
of coffee.
One of the drawbacks of low-energy bulbs is that they can't be used with
dimmer switches, which many people use in living rooms, myself included.

Yes, some of the multi-LED high brightness torches on sale now are very
bright indeed.
One of the off-putting things about Scr*wfix is that if your order is less
than œ45.00, you have P&P costs of œ4.50, but their stuf is always well
packed and delivered next day. However, we have a local depot so I can
just pop in for any bits and bobs so P&P isn't an issue for me.
Incidentally, when we all use difrent currencies, cost comparisions can be
diffcult and become meanigless, so here are the exchange rates as at
today. I'm not saying that's what we'd get at the local bank for our
holiday currency:
