Only the very early versions of CFLs I purchased were slow to reach full

My experience has been that they're fine when new, but as they age, they
take longer and longer to reach, or even approach, full brightness.

I had been under the impression from previous discussion that this was
attributed to the deteriorating ESR in cheap capacitors, but that view
doesn't seem to be getting any support here.
