What brand of halogens have you identified as unreliable?

**Crompton, but I've tried others.
Their incandescents are shit as well. Just burnt out a pair of candles

Guys like Tony Abbott, John Howard and George W Bush are hardly

Now THAT is proven beyond all doubt! :-

Your problem is that you are assuming that everyone follows those loons,

**"Fake AGW theory"? Provide your scientific evidence which contradicts AGW.
Naturally, I expect your alleged 'science' to be peer-reviewed. Like your
previous nonsensical posts, you will fail to back up your claims.

This sort of fraud and manipulation (the 21st century's "Tobacco

brings even well established scientific principles into disrepute and
question among people.

affordable, reliable 24h electricity on demand, and our ability to

Religious Nutters ??


When there is an opportunity of tax and power grab of a scale
unprecedented in modern times at stake (The carbon tax in the US
alone has been estimated to end up costing an extra 20% to consumers
on all current energy costs)
20%, is that all?
That's pretty cheap IMO for a sensible and ultimately needed move toward a
more sustainable energy future.
If you complain about the cost, how about trying to use 20% less?
People have enjoyed (wasted) cheap energy for far too long, time for that
mind-set to change I recon.
Just like people who complain about the price of petrol - even at it's most
expensive it's still cheap, ridiculously cheap.

So only scientists that *you* disagree with come into these three classes.

Lets take an example of *real* scientists.

Thalidomide was a drug wildly acclaimed in the late 50s/early 60s and given
to pregnant women as a treatment .
William McBride, an Australian medical scientist, showed that the drug was a
major source of birth defects and was rightly honoured for this work.
Some years later, this same *real* scientist was struck off the Australian
medical register in 1993 for falsifying data on a project.

http://www.newscientist.com/article/mg13718620.800-thalidomide-hero-found-guilty-of-scientific-fraud-.html
"William McBride ...... has been found guilty of scientific fraud. Last
week, a medical tribunal concluded that McBride had deliberately published
false and misleading scientific reports and altered the results of
experiments."

Who's correct? I don't know. The only thing
I'm sure of is that you don't know either, even though you may
believe one line.

**I believe the DATA. Nothing more. The data is compelling and
obvious to anyone who is not a religious nutter, a moron or a fossil
fuel apologist. Here's a short list of AGW deniers:

John Howard - Fossil fuel apologist, scientific illiterate, religious

Tony Abbott - Religious nutter, scientific illiterate.
George W Bush - Scientific illiterate, religious nutter, fossil fuel

Richard Lindzen - Fossil fuel apologist (on record as accepting money

Prof Ian Plimer - Fossil fuel apologist (ironically, he told lies in

You're in good company.
I'm neither a moron nor scientifically illiterate nor religious (as a nutter
or otherwise) and have zilch to do with the fossil fuel industry, other than
(by necessity) purchasing its products as no doubt you also do. Name
calling based on nothing demonstrates your attitude and does you no good.
Except in the lack of abusive profanity that he uses, you're no different
than Allison.

Having a discussion with you is like belting one's head against a concrete
wall. Your constant making up and posting wrong conclusions about your
"opponent" based on no evidence as you've done with me shows your make-up.
You talk of data, I doubt you even know the meaning of the word.

I am not sure what type of transfromer I have fitted.

I have been seriously lookiing at T8 fluorescent tubes as a good energy
efficiency replacement but I then have to do something with all the
downlights. It would be ideal to be able to fit leds in the downlight
fitting, however, the capital cost is too great.

I understand T8 fluorescents now exceed 70 Lm/w light output, and the best
leds are made by Cree and produce around 70 Lm/w, with the light output in a
led downlight situation more efficiently used due to the radiation angle of
the led. With the T8 loosing some portion of it's light output to the
fitting/reflector. Assuming a 32w T8 fluorescent produces around 2100 Lumen
with a directional efficiency of say 75% (guesstimation ) you will have
around 1575 lumens of light. To achieve the same light output from leds with
the same (70Lm/w and 80Lm/led) efficiency will require 20 Cree leds and
associated driver circutry. The number of leds can be reduced by increasing
the voltage and corrent, however, the efficacy then drops down.

I didn't realise fluorescents were as high efficicent as they are until I
did some research, however, they do lose out to leds through not being as
directional.

Err, you fill them of course.
It ain't hard.
I used slightly thinner gyprock sheet cut into a circle just slightly
smaller than the hole and glued that onto another square backing piece of
gyprock a bit bigger than the hole. Then you have a nice plug you just drop
into the hole from the top and glue into place. You only then need a minimum
of gap filler putty instead of the large gap stuff which is much harder to
use. Let set and sand to a smooth finish, then paint.
Much easier than it sounds actually, I plugged dozens in a matter of hours.
