I have 3 downlights recessed into the landing ceiling. I am on my second dimmer (60 - 400W). The bulbs fitted are dimmable (according to the box). Presumably dimmable means they'll continue to work off a lower voltage? Why would 'non dimmable' bulbs affect the dimmer switch? If my bulbs are dimmable, what might have happened to the dimmer switch?
