There's no problem using CFLs either base up or base down and
vibration shouldn't be an issue either (unlike most incandescents).

1. Is there an issue (heat or otherwise) mounting a CF upside down?
2. Are they suitable in a high vibration application, such as this?

I put a CF in mine, just checking before I shut it all up again
It's over the stairs and a PITA to get to).



Some CF bulbs have warnings against 'fully enclosed indoor use'. Not
really sure what this REALLY means, since I used some inside globes
and they have small vent holes in the base. I wonder if this means
like air-tight.

Follow the directions, I think even some CF bulbs are marketed for
ceiling fans too.

i believe the heat build up is reason they do not want them inclosed.
i believe the cfs can't stand the heat as reg bulbs do.
