Came across a 23W dimmable CFL. Got one to try it out.
It worked ~2 hours and pop, it went to full brightness and
no more dimmable??!! Are they this unreliable? Or I got bad one.

Please tell us the details!

The usual "dimmable CFL" to most looking for those means one that is
safely usable with a "usual light dimmer". I find it hard to believe a
lamp refusing completely to be dimmed by a usual-for-incandescent-type
dimmer. Non-dimmable lamps tend to have short life expectancy when used
with a dimmer against their instructions, and may blow the dimmer.
Usually the lamp is what dies.
