If you just need one, buy a fluorescent lantern that runs on 12V and pirate
it. For example, the Rayovac SP8DA Black Sportsman 8D Area Lantern runs on
8 D cells and has two 9W U shaped F9W-1 bulbs. Can run either one or both,
so it should be happy with your 8 watt bulb, and has lots of good reviews
for quality and longevity. Under $50 at amazon, I'm sure you can find it
cheaper. Or Makita makes a 12V trouble light, and I'm sure many others do
to, you might even find one that uses your f8t5 bulb.

Does anyone know where I could find a 12V ballast for a F8T5 fluorescent =
have a scanner where the main board has quit powering one of the lamps.
That's a strange choice of lamp for a scanner.
Scanners usually use cold cathode tubes (or LEDs nowadays).
Bare in mind that the lamp wearing out (electrode emission material
all sputtered off) could stress the ballast and cause it to fail if
not properly designed. So if you get a new ballast, might want to
change the lamp too.
The scanner is an old Hasselblad Imacon Precision II/III film scanner. The
is fixed, and the film moves around a drum as it is scanning. There is
out there that compares with the output of this scanner, and the new models
even better. There are a lot Precision IIs out there, and Hasselblad
supply motherboards for these anymore. The lamps are standard Osram lamps,
the ballast for these is integrated on the motherboard. New models of this
scanner sell for around $15K-$20K, so the older models are well worth
question is for another person, as my scanner works fine, but eventually it
need to have electronics replaced. There is also some talk about replacing
entire motherboard with a modern micro board (like the Arduino), and having
lamps powered directly from an offline ballast.
It looks line the CCD is connected to the motherboard via a serial link, but
haven't done enough investigation to know that.
