I had some lights similar to these in use in my bedroom ceiling fan since 2010. I think they are made for Philips by TCP. I just recently took them out to give AmbientLEDs a shot.
These are probably the best cfls you can get out there now, haven't heard of any bad EOL with any Philips cfls at all! They have changed the design recently and Philips cfls look more like the sylvania micro series
TCP makes many manufacturer's spiral CFLs, including some Sylvania and GE lamps. I'd say somewhat more than 50% of the lamps are fine, but plenty die early.
Mike, if you have a fixture that looks like a ice cream cone then it would be decorative.
