CFLs 10 pence each at Dunelm
 

Hello,

I've just seen Dunelm are selling CFLs ten bulbs for one pound!

They are made by Osram. That's a good make isn't it? They are in 8W
(40W equivalent), 60W (11w equivalent), and I think, 14W (75W
equivalent).

Has anyone tried them? I was thinking for that price it sounds as if
you can't go wrong. Do they light instantly? I once bought some from
toolstation (CED brand) that take 30 seconds before they light!

Thanks,
Stephen.

Osram are a very good brand, thats a real result.

Your power equivalent figures are rather optimistic though, 4x is more
realistic.
So 30w, 40w, 60w really.

And only if you can see in infra-red.

Now the world has gone to bed,
Darkness won't engulf my head,
I can see by infrared,
How I hate the night.

Now I lay me down to sleep,
Try to count electric sheep,
Sweet dream wishes you can keep,
How I hate the night.

These figures are essentially lies. You may get 4x equivalence if you're
lucky, but it's closer to 3x in a lot of cases.

Yep, I concur, 20W CFL from tesco matches a 60W incandescent.
I put the crap 8W british gas free ones I've had for 2 years in the
cupboard under the stairs. Other half said "it's a bit dark in
there !".
I put in there so as not to burn my nose when changing the CU last
week.
They still get pretty hot.

Don't shoot the messenger! I'm just telling you what was on the box.

I have bought some 8w and 11w cfls to try. From my *very limited*
experience with a *few* bulbs it seems that the 11w bulbs light
instantly whereas the 8w do take a fraction of a second to light. I
can't understand why there is this difference between the two
"wattages" since they are the same make. However the delay with the 8w
bulbs is no worse than the other makes I have used in the past and
certainly a lot better than the CED offerings at Toolstation which
take 30 seconds to light!

I have used the 8w in small bedrooms and 11w in larger rooms: big
bedrooms, lounge, etc. I haven't noticed a difference in light output
but I know that cfls are emotive on this newsgroup so all I can say is
that this is IMHO and YMMV etc.

11w seems to be a standard rating for CFLs yet the next rating down
varies between manufacturers: some offer 8w bulbs and others offer 7w.
I wonder why there is this inconsistency. Still I guess 1w per year is
probably neither here nor there.

One last question: what is the storage life of CFLs? IE life when sat
on a shelf, not plugged in. If I bought a spare box to take advantage
of the offer, would they still work in five or ten or twenty years
time or does something happen to them with age?

These won't exist in five years time.
