Surpassed only by the great Vegamite/Marmite
and LPG is cheaper/safer than petrol/diesel debates.
This phenomenon relies upon the first law of packet - the immutable law
of perpetual regurgitation of trivialities. A law which - like the force
of gravity, has never been known to fail.

I think that's the main drawback with them Andy.
So many lights tend to be in rooms in which we need instant illumination
for only for a few minutes - on landings, toilets, etc. Our kitchen has
four 60 Watt R80 reflectors - they're starting to become less obtainable.
I've got a few long-life ones left from Scr*wfix who don't stock them
anymore. A neighbour has gone over to CFLs - I think they're 11 Watts
each - quite neat, and when they're up to full brightness, excellent.
But when they're first switched on, they're really dim and take several
minutes to come up to full brightness. As a result, he leaves them on all
day and night, which rather defeats the object.
We have an 8W one on our landing for when our granddaughters come to say
as we leave it on through the night so they can find their way to the loo.
I can't be bothered to keep changing it back and forth to a filament bulb,
but if we switch it on to just go up and downstairs, it's hopeless.

I haven't been following this debate, so apolgies if I'm going over
well-trodden ground.
The actual designs are getting much better - more compact and shorter,
and in some instances very much like the globe shape of a filament lamp,
and as you say Andy, CFLs radiate a different light spectrum from that
of incandescent lamps.
The claimed average rated life of a CFL is between 8 and 15 times that of
incandescents. CFLs typically have a rated lifespan of between 6,000 and
15,000 hours, whereas incandescent lamps are usually manufactured to have
a lifespan of 750 hours or 1,000 hours
It's said that the life of a CFL is significantly shorter if it is only
turned on for a few minutes at a time: A 5-minute on/off cycle can shorten
the lifespan of a CFL can be up to 85%, reducing its lifespan to the level
of an incandescent lamp. The US Energy Star program says to leave them on
at least 15 minutes at a time to mitigate this problem.

They're much cheaper now than when they first came out.
Of the ones we have, we've not had a failure.

It doesn't need artificial light - it's the land of perpetual sunshine.
I can feel a song coming on:
On a summer's day
In the month of May
In Albania^H^hay-hay,
A burly (Cotting) Ham came hiking..
As he roamed along
He sang a song
Of the land of milk and honey
Where the frogs do play
Where a ham can stay
For many a day
And he won't need any money
Oh the buzzin' of the bees
In the bulletin trees
Near the soda water fountain
At the lemonade springs
Where the wind farm sings...
And the veekays are so happy.
In the new-mown hay
They can sleep all day
Or on packet play
And the bars all have free lunches
It's so hamidacious,
The locals are so gracious
And they're very perspicacious
They're always so polite -
Never argue or fight
And on summer nights
The CFL's shine bright
Except the ones from China
When a resident whiner
Says it all becos
They're not made in Oz
No other place is finer..
I've never been, but I'd love to go
Cos there ain't no snow
And the sleet don't fall
And the winds don't blow
In Albania^H^hay-hay
Where the sun shines ev-er-y day,
The trolls do play
But never read 6k...
That 'EBT just won't go away...
Ohhhhh, theeeeeee buzzin' of the bees..
And the lemonade trees...
With apologies to Burl Ives.
Ho hum
I've saved a fortune on utilities bills this last year.
Not electricity or gas, (my house is heated by hot air ducted from my
bulletin factory), but on water. A year ago I installed a new loo.
I kid you not - one that caught my eye complied with the Oz water
conservation regulations - low water capacity, dual flush and a super
efficient siphon.
As an honorary Aussie I couldn't resist it.
It's cut 25% off our water consumption and works a treat. I only had to
wish John Sorry-Me-Not Smuggingtions-Howard down the gurgler and he was
gone - one minute he was out on his morning stroll next minute - well,
I couldn't bear to watch - whooooosh - he was a goner.
So he wasn't "Howard the Unflushable ...." after all.
Quote of the day:
Absurdity.
"The fact that an opinion has been widely held is no evidence whatever
that it is not utterly absurd; indeed, in view of the silliness of the
majority of mankind, a wide-spread belief is more likely to be foolish
than sensible".
(Bertrand Russell, English Logician and Philosopher 1872-1970).
