Just in defense of Sonntek re. excerpts below. We've used their lamps for
years, and had good interactions with them as far as returning a couple of
lamps ~2yrs ago when we thought it was a problem with the lamps. (The
problem later turned out to be in the 1090). The head of the company (can
never remember his name) usually answers the phone, too, which I think is
an advantage. I gather that these companies buy lamps in bulk from a
manufacturer and cement the various bases to them. Too bad there's no
return credit for the base, which for a 1090 anyway can't be that cheap!
