*if* you had a neary thunderstorm and *if* youhd electronic
ballasts, they might have been fried by an electromagnetic pulse.

You don't need to take a direct hit from lightening to
sustain damage. We live way out the country and see a lot
of this, modems, fax machines, etc, can be zapped after
a storm easily and commonly. Can't say I've *ever* seen
a fluorescent light taken out, but it's pretty clear something
zapped yorus.

FYI there is a $100 surge protecter that is backed by the
manufacturoe that will replace anything that gets taken out
if it's used. A friend of mine gor 5 new computers when his
got zapped without any hassle.

You're right, it's going to be expensive. Common magnetic ballasts
are the cheapest, but you'll probably find light fixtures with
ballats for the same price. There are cheap elecronic ballasts
and good ones. The latter (Advance, etc) are worth it if you
want to spend a forture. I don't, I use cheap fixtures
and GE Super Daylight bulbs (the old SPX65) and have no

They're a bit low on red as most fluorescnts are and
I've found a $70 (CDN) high pressure sodium 70W
"security" light is more than adequate to make up the
missing red when/where I need it.
