CF in enclosed fixture

I have a "jelly jar" fixture above my backdoor.

Can I use a CF in this type of enclosure?

I know CF's used to have issues with totally enclosed fixtures, is that still the case?

I know it probably is a proprietary issue but generally?

They are technically not supposed to be used in totally enclosed fixtures because the heat buildup affects the ballast. Same reason you're not supposed to burn them base-up in a recessed can light or ceiling fan unless it is specifically rated for it..

But that said, people do it all the time. While I doubt it is an actual fire hazard, I have noticed that it definitely adversely affects its useful life.

I have a 23W (100W "equivalent") dimmable CF lamp installed base-up in the schoolhouse globe that's part of the fan over our dining table. The control is an SOP dimmer - not CFL rated. The lamps last 2 years or more.
