"is it dimmable" refers to the use of a phase-cut TRIAC dimmer in combination
with a retrofit LED bulb designed to run on mains power.


No, some bulbs are not dimmable, period. Some are. None work reliably
with triac dimmer controls.

According to independant reviews by people NOT selling light bulbs, some
manufacturers bulbs do.

The ones you are selling do not.

It's going to be years (if ever) before such standards are created for
the residential market. There are too many reasons to stick with 117V
wiring.

The standards are being actively developed and have nothing to do with
altering the wiring voltage and everything to do with dimmer and bulb
technology.
