I would not recommend using a fluorescent lamp onboard as I have found them
to be unreliable in high humidity environments.  Someone once attempted to
explain to me that a fluorescent tube required a good ground reference
(fixture) to light properly.  OTOH, I do use a portable fluorescent while
camping and the only objections I have are the squeal of the oscillator in
the AC inverter and the flicker as the battery gets low.  I suspect that the
inverter efficiency is probably only about 60%, making fluorescents less
desirable from a power consumption standpoint.  Does anyone have figures on
it?
