Found! An Electronic Device That Actually Needs A
Burn-In Period.

The last batch of dimmable compact fluorescent bulbs
that I bought. Takes about an hour's use before they can
be dimmed way down. Before burn-in, they flicker at
lower settings.

I haven't seen those. I expected someone would come out
with one sooner or later.

Handy-dandy little gizmos. These net out to being about 6 times as efficient
as the bulbs that they replace.

IOW they put out about 3 times the lumens, but use only 40% of the power.
They do not appreciably change color temperature as they dim, and the basic
color temperature is very a very natural light.

What are they like ?

They look just like non-dimmable CF bulbs, with a slightly bulbous ceramic
base and a spiral bulb.

I'd be intrigued as to the 'burn in' mechanism.

Possibly related to re-distribution of the material that feeds the arc.
