Does anyone know where I might get a ballast to drive a 9W CFL tube (germicidal lamp) from a 6V source? There are a number of good circuits around, but all require a custom-wound transformer, which would be difficult for me.
A bare circuit board is fine. Don't want it enclosed in a metal case.
I need 10 of these things.
Thanks in advance.

The easy way to find one, is to get a fluorescent battery lantern; the common camping types run on 6V from four D or AA cells
The 6 V input might be hard to find. Maybe use something with a 12 V DC input, like
Matt Roberds
The ballast ICs use switching-supply frequencies on their transformers, which means you're limited to a few hundred turns at most, not too many to do by hand. For 10 pieces, make a little fixture so your hand drill can turn the bobbin. Usually an accurate turns count isn't that important.

Gets a bit pricy for 10 of them.
