Anyone know anything about doing this? My dad has recently installed an extra light in his lounge to run off the same dimmer switch as the original light, so now he has 2 lights in the lounge running off the same dimmer switch. Only problem is that the lights switch on and off but won't dim. Has he made an obvious school boy error or does the system just not work like that?
I'm not sure how he has wired it but any ideas would be appreciated.
