I have two strips of track lighting in an enclosed porch, each with two
Lightolier 9320 fixtures, one of which has broken. I've found exact
replacements on various websites, but I see things i like much better made
by other companies. Are the mounts all the same, or does each fixture
manufacturer also make some special flavor of track? I guess that part 2 of
my question is, will all Lightolier fixtures fit my existing tracks? I like
the looks of some of their other fixtures better than the ones I have. Some
of the other brands are Juno and Nutone, but there are more. I can't tell
from web pictures what the mounts look like.

Lastly, this broken fixture is broken in the mount area, which looks like it
comes off. Are repair parts available somewhere, or is that just crazy
thinking?

thanks in advance,
Keith
