Hmm, I can't say I've noticed that particularly. I do have one of
those 'natural light' spiral type CFL's and that is VERY white!

I've a worklight with three CFLs.

Oooh, I was looking at those with the though of being able to rig a
couple on a stand as a field work lamp to go with my little genny (or
inverter if it came to it and assuming it worked). Summat like this
maybe:

Originally they were all daylight. one
failed and was replaced by a standard (too)warm white. It now look as if
it
has two blue bulbs and a red bulb when viewed with them all lit.

Oooerr. Without a doubt if you only exposure to CFL's was this natural
light jobby I've got here you wouldn't like them. You wouldn't think
you could have a light that was too 'white' but you can [1].

The choice of colour temperature of CFLs is very poor, 3000k or 3500k
would
be good, 6500k (daylight) is too blue and 2700k (the usual)is too red, but
that's generally all that's available.

Ok.

Many years ago, when my parent's eyes were aging and they had a 200w
incandescent lamp behind their chairs to read by,

(feck!)

I replaced the central 200W
lamp by a 6foot /white/, not /warm/ white, fluorescent, and they never
needed
the reading lamps again.

;-)

They'd probably have burned the house down.

And didn't need any heating on either I suspect.

What we need is higher colour temperature CFLs.

No, the last thing any of us need is a choice (too confusing /
frustrating / expensive).

[1] It's part of my gripe about HID headlights. Whilst they may be
great for the rider / driver IMHO they are just_too_bright to be
comfortable when you get a face full of them on a roundabout or
country lane (as will happen no matter how well adjusted they are). As
humans we have a range of comfort. How hot or cold we can be, how much
weight we can lift, how much 'G' force we can take, how much noise we
can stand and how bright a light we can look at without making us
wince. For me, HID headlamps are outside that range.



They're not actually *that* much better from behind the wheel. Good halogen
lamps are perfectly adequate on the roads in this country. There used to be
very robust legislation about how the lighting on cars was designed. As I
recall, there were laid down specifications on how high lamps could be, and
how far apart, and visibility angles and all sorts of things. Now, it seems
that car designers are perfectly ok to decide on the overall shape of the
car to make it look pretty, and then just fit the lights in where they can
so as to not spoil that prettiness any more than they have to. Some of the
rear lighting on cars now is, IMHO, totally inadequate in all but the most
ideal of conditions, whilst others' rear lighting is so ludicrously bright,
that it dazzles you even in daylight. I often wonder how many of those
inexplicable traffic stops that occur on motorways nowadays, are caused by
drivers over-reacting on their brake pedals, to the red searchlights coming
on in front of them, when that driver just touches his brake pedal for
whatever reason ...
