I've just replaced a light switch with a dimmer switch - the switch serves a ceiling light in which I've been using three 25w candle bulbs. The dimmer switch is wired EXACTLY the way that the instructions gave and also matches any pictures I've found on this site - ie. red to common and black to L1.
Both the light and switch work fine, but when the light is swtiched off the filaments in all three bulbs continue to glow. Have I done something wrong or is the switch faulty?
Any ideas anyone?
