I have a dimmable LED light on my sewing machine that works very well.
It has eight LEDs and you can turn on two, four, or all eight.  But
I've never seen this feature on mains-power lights.  Pity; if you had
enough LEDs that size to illuminate a room, you'd have reasonably-fine
control over the brightness.
