"I must respectfully disagree with Bob, here. His answer is true for
some of the very poorly-designed and horribly-overpriced tubes sold
at your lfs. Most tubes sold for commercial and residential uses
retain most of their output until the gas will no longer sustain a
discharge. They are available in as good or better spectral
distributions, too. Total drop in brightness is maybe 10-20% until
they no longer fire. There are some lfs exceptions, like Triton
(overpriced, maybe, but at least well designed)."
Wright, could you give a list of specific household bulbs which are
both well-designed and of "as good or better spectral
distributions"? This would be very useful information.
