I 'suspect',  as we say around here, that some folks may soon be wishing
that their 3-year-old CFLs _would_ fail prematurely ;-)

Some inexpensive and widely available CFLs apparently improve on recent
predecessors in most areas of concern.

A $1.70 n:vision  2700K color temperature (incandescent-like) CFL from
Home Depot was cooled down to 0F (-18F) in the freezer and then turned on.
It went to within 1/3 stop of full brightness measured with a Zone
VII-modified Pentax spotmeter in about 50 seconds.

Starting at room temperature, they reach full brightness much more quickly
-- effectively right away as far as my perception is concerned. By the
time my pupils and other perceptual cues adjust, they are essentially up
to full brightness. The residual perceived increase in brightness is minor
(but the increase is still easily measurable with a light meter). If I
weren't attuned to the warm up, I probably would not have noticed. Faster
than my old four-foot T-12 shop fluorescents.

Did you mean to spell that with a "c" ?

If so, I'm afraid that you've mistaken me for someone else.

I  am *not* the "coot" ;-)
