I made a chimney out of an Anchor Hocking microwaveable food storage bowl. It
looks simliar to what your description of the lighting fixture sounds like.
However, it passed the test John mentioned. Putting it in a microwave (along
with another container of water) gave no heating at all. It's been working fine
for two years. These food storage things are hard plastic, and come with ears
that make them easy to mount. They are in two sizes, one is about the size you
describe, the other is smaller - pefect for a 4CX800.
