Well in all fairness...


Seen any CFL's that'll work outdoors in the winter? I need a few for my yard
lights.


Yes, plenty of enclosed CFLs work outside in the winter. If you live in
an area of extreme cold, there's always HID. A 39W metal halide lamp
produces much more light than a 150W incandescent, and lasts 6-10 times
as long. I use exclusively CFLs in all my outdoor fixtures, it only gets
down to about 15F at the lowest here, so the plain exposed spiral type
work fine. Since these are on from dusk till dawn, the savings are
substantial and I get 2+ years out of a bulb. Even the vilified mercury
vapor lamp so common in yard lights and street lighting of the past is
more than twice as efficient as incandescent.


Got any that'll work on 3V DC? Need some for my flashlights.

Yes, I do, but what's wrong with LEDs? They're perfect for flashlights.
You can pick up a 3W white LED Maglight for $22 at Home Depot, they've
really come down in price, work better, and the batteries last longer. I
do have a fluorescent flashlight, it uses a small cold cathode tube, as
well as I have a camping lantern with a conventional 9W CFL tube in it
powered by 4 D batteries.


Will
CFL's work in cars? Lots of incandescents there.

Not very many anymore. LEDs and HID are making rapid headway into
automotive applications as prices drop and technology improves. I'd bet
that within a decade there will be virtually no incandescent lamps
anywhere in new cars. No more taking out a zillion screws and clips to
dig into the dash and replace lamps, no more burned out taillights, or
melted lenses from someone installing the wrong bulbs. There's no delay
as the lamp filaments heat either, so response of the brake lights is
quicker, not by much, but at 70 mph every millisecond is valuable.
