Hi Lee, Thanks for the suggestion but no, there is not - I can push the glass up a little but it is definitely not able to be pushed in and then down... I can't believe how hard this is.
We both looked at it and played with it to no avail.

Any other ideas?

Don't know then. The housing is "painted on"? It shouldn't be. If you think you need to remove the entire housing, try taking a box-cutting knife blade carefully around the edge of the fixture, holding the knife almost sideways, to break the fixture free from the ceiling paint so it can be removed without taking chunks of ceiling paint or drywall with it.

I have some MR16 'wall washers' that look something like those. You simply have to pull the housing down and out to access the bulb.

Agree with the post above about using a knife to carefully cut the paint around the rim. Razor blade or xacto-like knife would also work.

Did you ever find an answer for this?

With that kind, you will need to do as suggested above, and cut close to trim ring, to lose housing enough to pull down. You access light from behind. There will be two thin metal brackets that are spring loaded that will prevent it from falling off ceiling, so unless you squeeze those, it will only come out about 2 inches.
