Hi, we have one of those energy saving bulbs installed in a room. The
bulb is installed on the ceiling light fixture, facing downwards.
Recently it burnt out and when we were replacing it, we found signs of
heat damage. Any idea why this would happen? Is it OK to deploy these
bulbs on the celing, facing down?

Here are 2 pictures of the bulb:

That's pretty much the normal appearance of a compact fluorescent bulb which
has reached end of life.
