So get an inverter already.  Car battery + inverter + CFL in an
"automotive hood work light" worked fine for me.

The better brands have a silicone sheath in addition to the glass,
to capture both the shards an the vapour if possible. Check out Megaman
brand in particular, that's the one I know about.

Yes I've heard of Megaman, they seem to be well thought of. This wasn't my
light fitting though.

I've also tried different phospors and my, 5000K looks really odd. Plus you
can get 6400K too. 2700K is the norm AIUI IIRC and if you look around there
are some at 4000K.

The 5000K would probably be good for bench work. Plus it was about 30-35W !
That was bright but a halogen looks nicer.

Good, but not completely unbeatable.  Dollar store pencils, twenty to
a package, can be made into carbon arc rods, and the resulting
arc lamp:
(1) is brighter,
(2) generates more ozone
(3) does more damage to local RF reception
(4) is cheaper to re-lamp

than even the best CFL lamp.

Seriously, the CFL retrofit to AC lamp sockets intended for
incandescent lighting, even though it's the darling of the
green set, is a stopgap solution.  In the long run, disposable
lamp-plus-electronics isn't the best technology.
