[quote Mike Johnson]Just because some cf bulbs are rated for use in an enclosed fixture doesn't mean the fixture is rated for that. The glass bowl on an enclosed fixture can shatter from the heat. It could kill somebody.
Not sure what you mean by that. CF bulbs are cooler than incandescent. So if a fixture can handle an incandescent, it can surely handle a CF.
The ones in my kitchen have been there for a couple years at least. They are certainly still brighter than the incandescent equivalent.

CF bulbs quickly lose about 10% of their brightness, and then slowly lose more.
You can't really use the 13w cf = 60 watt incandescent equivalencies, because A) 60 watt bulbs from different manufacturers could put out widely different lumens, and B) CF bulbs dim as they age.
