  • Odd problem with the dimmer switch @Airhead recommended recently:
    https://www.tlc-direct.co.uk/Products/VLMKP100.html

    We have a light with five 5w LED pendants. The dimmer switch is to replace one that died when one of the LED bulbs blew, tripping our consumer unit and frying the dimmer.

    I got a replacement bulb and all five LEDs were working fine with a standard on/off switch.

    Fitted the V-COM dimmer and now the dimming works but only four out of five LEDs are lighting up!

    I haven't tested this by putting the standard switch back or swapping bulbs round, but I'm fairly sure another bulb didn't just blow... What gives?!

  • Obviously try replacing the bulb that doesn't light or test it for continuity before you try anything else. I'm at a loss to think of any other scientific reason why the dimmer would stop one bulb out of 5 from working.
