have one in a light here and I cannot tell its on after half an hour to the

CFLs are not all that efficient and a 23W one is really pushing it for
efficiency and dissipation needed to stay cool enough to survive. In
anything other than free air with plenty of convection it will fail.
I wonder why its heating up unless its a cheap under rated chinese copy
that will fall to bits when the heat glue melts liike one I had from B/Q!

It is heating up because of losses in the power supply. Unlike filament
bulbs a CFL or LED has a rather low maximum operating temperature.
