I do not know much about fluorescent tube ballasts, but I can give some
general guesses.
1) Wattage is going to relate to total amount of heat dissipation that
the ballast can handle.
2) Tube length (each in parallel or both in series) relates to the
voltage needed to first strike

I guess so, it's just, well... I'd like to _know_. :)

Another solution might be looking at the circuits that excite the tubes
with high frequency. With a simple oscillator, you can use the tubes
without the filament, and if they still have gas, they

I can find plenty of general information on how fluorescent tubes work,
but no specific advice on ballast selection.

Hi all,
Sorry for the OT post, I've googled this to death without finding an
answer and was hoping someone here might know.
I recently purchased an old, second-hand UV exposure box to try making
PCBs at home. One of the tubes has started to fail and in replacing
them I have noticed something odd
