Re: shop lights

Well, it's not a big deal as I can replace them cheaply, but I do thank you
Jim for all your technical expertise.  I learned a lot.  Interestingly, the
longest-working fluorescent fixtures are the shop lights in the garage.  The
one over the workbench has been burning the same fluorescent bulbs for at
least 15 years.  The ones I have trouble with are the ones in the house on
the lightstand.

I'll check on the availability of freecycle to see what I can find;
otherwise $8 at Wal-Mart.  Really not a lot of money.
