re: Fluoro tubes from Europe
Most (all?) of Europe uses a 220v line voltage. I used to be sure it was
all 50 Hz too, but I was working with a group of Germans several years ago
that told me they were switching over to 60 Hz. Switching line frequency
would be a *HUGE* undertaking for all kinds of reasons (motors and clocks
would run too fast for example), so I don't know if they understood what I
Anyway, if you need to get 220v to run some European electrical equipment
you can get 110 <-> 220v step up/down transformers from All Electronics
(http://www.allcorp.com) in sizes from about 100 VA to about 3000 VA.
Prices are pretty reasonable.
I would think you should be able to run a 50 Hz ballast on 60 Hz without
any trouble, but starting might be different (not sure on this). Most
transformers can operate on higher frequencies without a problem, but it
does NOT work in the other direction. I suspect that the secondary (bulb)
side of the ballast would behave the same as north american ballasts unless
the lamp design is different.
BTW, Japan uses a nominal line voltage of 100 volts, at I believe 60 Hz.
