... so, how do they work? Special bulbs? My daughter has them in her
kitchen. Pop the bezel off and you can choose from cool white, daylight or
warm white. Look like pretty standard GU10 downlighters.

Not GU10 ones, but the switchable thin panel ones I've been told simply
have multiple sets of LEDs.

Well I can make an educated guess that the white is made out of integrated
LEDs of different colours and by changing the amount of light from the
different colours one can change the apparent colour temperature.
Certainly this is not a new idea, several illuminated magnifiers for the
partially sighted had this feature almost as soon as white leds came along.
