[Tig] bulbs for the home

A Happy New Year to One & All. 

To those who performed excessive BRRE over Christmas and will take some
time to recover Happy Easter

I too dislike the effect of the non-continuous spectrum emanating from
fluorescent lamps. 
I have yet to see any that have as comfortable a visual feel as
incandescent lamps.
This is strange, as I have no problem looking at a CRT or LCD that has a
substantial non continuous spectrum, fairly narrow R, G and B.  
The BBC used to use 1ft fluorescent tubes wrapped with ND filters that
provided a grey scale wand. 
This was used to set up colour monitor luminance, colour balance and
tracking. 
Held horizontally just above the monitor it was ideal as all that was
needed was an eyeball match between the wand and CRT.

I agree that Incandescent illumination is about 90% heat, however here in
the UK for up to six months a year it helps with keeping the 
house warm, so long as the ceilings are well insulated. As a downside to
ceiling recessed down-lighters, this heat can be lost in the void. 

Don't get me started on Global Warming , but; our government seems
determined to use the apparent effect to lump charge after charge on us. 
I would be happy with this if they also agreed to return these charges, if,
in say 20 years, 
we find it was all natural and everything we did had no effect whatsoever. 
There, I have stuck my colours to the mast!  

What is one of the worlds most inefficient machines ? 
A telecine of course. 
Anything up to 3KW into the beast, and, if it is analog PAL or NTSC. 
Then a maximum of 1V into 75ohms out, around 13mW. 
Now if you are a green then I suggest that the telecine efficiency can be
improved by a factor of around 400 
simply by turning the audio up so as to use 5W for sound, a continuous tone
will be required to maintain the efficiency.

While on efficiency subject, but off topic, can anyone tell me whether the
following is true.

A typical car creates less pollution during its used life than the
pollution generated to manufacture, 
destroy and/or recycle parts of it. If this is the case why is everyone
trying to get us to replace our cars 
with more efficient ones rather than suggesting we keep them till they
drop. 

I have heard that the Jeep Cherokee is, under the above reasoning, one of 
the least polluting cars in the world. No I do not own a Jeep!
