You can buy halogen replacements, which are pretty much identical
albeit more expensive to buy and less expensive to run.

Or you can readily buy dimmable CFLs these days.

If you really like the stone age, it is more authentic to light a fire
in the corner of the room.

There is nothing wrong with liking something as it was, such as
tungsten bulbs. My wife reacts to fluorescents, they give her
headaches.
Funnily enough, I am about to by a wood-burning stove for the
house. Maybe we'll leave the door open, so we can read by its light. g

It would be interesting to find out what it is about the compacts that
causes this, as I too find them naff. However if you pay a bit more and get
the proper white ones, they seem to do this less. i suspect then that its
the el cheapo coatings used that are the issue. could be persistance of the
phospher or maybe the emission frequencies of the stuff, I don't know.

Probably due to their sharper rise and fall flicker...

Might also be related to their non continuous spectrum.

I must admit I am not sure why the quality of light from the compact
versions seems so poor compared to that from a traditional linear tube
ones.

Agree, I think it is that all CFLs available in non specialist outlets
have a low colour temp (mostly 2700K) probably in an attempt to match
incandescant. To my eyes, that just makes them an unpleasant colour and
seem dim. Linear lamps have always tried to emulate daylight and, at
least to me, preferable.

Also, converting our flourescent tubes to elecronic ballasts has made
them much more pleasant to work in as there is little or no 100Hz flicker.

Cost and size? Maximum perceived light output seems to be the selling war
- not the quality of it. And given the quoted light output is just not in
the same ballpark as most see from a GLS, it makes me wonder why they
bother.

It's rather like the official MPG figures for cars. Pie in the sky. So
only useful for comparing two similar products by anoraks.

No one's been able to find out, because in double-blind tests,
the claimed effects show no correleation with type of lighting.

There was certainly a measurable effect with poorly made
linear tubes running at mains frequency which end up
slightly rectifying and generating 50Hz or 60Hz flicker.
But that doesn't apply to CFLs.

Of course, you can buy cheap CFLs with poor coatings and
colour rendering, but they're actually quite hard to find
if you stear clear of no-names.

If you get high frequency fluorescents (electronic ballast) she should
not be affected.
CFLs are high frequency.

Quite. Although the implementation I see in most houses where they're
paranoid about changed to CFL is more akin to candle light, level wise.
But without the pleasant effect.

beware if running them at an angle. We have a load of these, and in the
dining room they fit in a lamp at something like 45 deg. Similarly, another
one fits horizontally. They fail really quickly - looking at them it seems
the filament isn't supported well enough and it drops and breaks. The ones
that are either in pendants or upright in table lamps are great and have
lasted well.

Or you can readily buy dimmable CFLs these days.

Ignoring the fact that many of these give horrible light, you have to be
careful using them with dimmers. Many dimmers (older ones anyway) have a
minimul wattage to work reliably - they won't all drive dimmerable CFLs
reliably.

Will halogens end up being phased out as well?

The GU10s in the spotlight plates I have a lot of in my house kick out
an almighty amount of heat. FWIW, I like this, because it saves
putting the heating on if it's only *a bit* on the cold side.

Oh yes - the fire IS the best option. Just started using ours this autumn -
make such a difference ! So I suppose by your view we are in the stone age,
but we don't think so - more the log age! Saves burning all that oil.

If you have all electric heating (assuming its not a heat pump system),
then there is no real energy saving advantage to getting rid of them in
the first place!

More to the point if using nuclear electricity a light bulb at 100%
efficiency is similar to oil at 40-50p a liter pricewise and creates no
CO2 at all.

Attractive idea except that heat rises so you will be adding heat to
where it eventually ends up that's why most heating systems are low down
close to the floor where all the cold air is.

Assuming you have other sources of heating, then it does not really
matter. If the air in the room is still, then the lamp will help heat
the stratified top layer, thus pushing the effects of your other heaters
down lower. If there are decent convection currents running in the room,
then the hot air will circulate.

You may already be too late, or you could be lucky and get some very
cheap in the 99p Shop or the clearance sections of other shops.

You can now get halogen bulbs inside ordinary light bulbs. These work
with ordinary dimmers, they come on instantly and, in my opinion, they
give a much nicer light than CFLs. They are slightly more efficient
that the traditional light bulbs e.g. 42W replacing 60W (but nowhere
near as efficient as CFLs).

I must check those out. Almost all my lighting uses small 40W screw-thread
reflector bulbs - if there isn't an alternative available I'm faced with
having to replace all the fittings.

It's only *some* tungsten lamps which are 'banned'. Mainly GLS (basic
lamps). 'Specials' - like it seems you have - are still available. Even
although they are generally less efficient than the old GLS types.

the larger bulbs use more power, which apparantly means more greenarse
gasses produced, which is killing the plannet they rekon, so get rid of them
and the greenarses can feel smug that they have done their bit to save the
planet,

don't worry, they'll get to the smaller bulbs in time, then they will start
moaning about the mercury in the cfl's and make us switch to led's, untill
someone points out something bad about the manafacture of them and they make
us all use fart gas for lighting... they produce enough of it, so may as
well burn it for light.

No you don't.

After the initial period where everybody mistakenly thought that it wasn't
allowed to sell 100W bulbs they are now easily available at a market stall
near you.

It will be ages before they run out of 60W bulbs

In that case it must either give out less light or less heat, and as

heating system for most of the year., so they are only more efficient in

Less of both.

As mentioned in another thread, I tried swapping 25W candles for
their replacements which are 18W halogens - noticabley dimmer.
Had to go up to the 28W version (which is supposed to replace 40W).
Actually, nowhere on the packaging for any of these lamps that I
have does it claim they have the same light output was the ones
they are supposed to replace. I can easily show with a light meter
that the 70W and 42W (100W and 60W replacements) are dimmer than
their original GLS lamps.

You've raised a point indirectly for me. I have 8 off 50 watt GU10 tungsten
bulbs on two dimmer switches, so thats a total load max of 200 watts per
dimmer. I recall that when fitting the dimmer switch, it needs a minimum
load to work properly which was 100 watts, SO I am OK if two out of our
bulbs go pop.

Now I have seen in my local Tescos that there are Philips LED GU10 lamps
that are 4 watts each and are compatible with dimmers.

So if I replace the 8 off 50 watt bulbs with these 4 watt dimmable LED
GU10's thats a load of 16 watts per dimmer knob.....

Have I got to change the dimmer switch as well?

Yes. You might get away with leaving the dimmer set to max all the
tiem, or switching it to max very quickly, but if you set it to dim
the CR power supply in the LED bulb will fry fairly quickly.
