I see all three versions of the lights list the Magnetic Control Distance as being 3 cm, but the videos appear to show someone actually touching the board with a magnet to make the light to switch.
I was wondering if the switch will actually work 3 cm away from the light and if so, would it still work if there was a 3 cm block of filament between the light and the magnet?
EDIT: It would be really cool if there were a version of this control switch light that just had two modes, on and off, rather than having to hit the switch several times to make it turn off.
