What percentage of domestic households have phase cut (light) dimmers in them?

Hello,
The above question, in any country of your choice?
The following says UK does not have many, and USA has many, but doesn't say how many.

I replaced all the incandescent light bulbs in my home with compact fluorescent ones that cannot be dimmed so I removed all the dimmers. Maybe many people did that.

there is a new type of dimmer that can be used for cfl dimming...it involves signalling to the bulb that dimming is required by simply chopping out a whole mains half cycle at the zero crossings....

Thanks, BTW, we are bringing to market a new type of LED lightbulb dimmer which will sweep the world!
It is literally just a pushbutton switch by the side of your light switch.......when you press it, a mosfet in-line with the mains live will switch off at the mains zero crossing, and then back on at the next mains zero crossing............a simple circuit inside the led lightbulb will detect this missing half cycle, and dim the led light down....or back up again if it was already dimmed right down.
As you can tell....you just keep pushing the button till you like the dimness.
...This type of dimmer, since it switches the fet at the zero crossings, will not damage any type of lightbulb.......obviously it needs the simple "detector" cct in the led ligthbulb, but that'll be easy to do.....it could also be doe with flu's.

Forget those old triac dimmers which just don't work with all types of dimmable led bulb...and indeed, leading edge dimmers can reduce led bulb lifetime if accidentally left on with a non dimmable led bulb due to resonances in the emi filter of the bulb.

Not one single dimmable led lightbulb on earth can work well with absolutely all leading edge or trailing edge dimmers on the market......its time for us to say goodbye to trailing edge or leading edge dimmers

schem of dimmer and schem of a led bulb that would use it attached.
-a CFLwould be dimmed by its driver receiving the signal then increasing the switching frequency

I don't have any VERY expensive LED lightbulbs and none of my family and friends have them.
Then how can a dimmer for them "sweep the world"? Maybe 20 years from now?
