    Can you wire 2 lights from one dimmer socket?

    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.

    Thanks.

    from experience, I think there are 2 fuses in a dimmer. 1 is for the dim bit, and the other for the actual light. I have had a dimmer blow before, and just the switch work.

    Check that the lights are mains and not transformed, and make sure they are both the same. There are different dimmers for each kind.

    You may be lucky, just buy a new dimmer.

    Yes, you can run two lights off the same dimmer switch.

    I think your dad has wired it incorrectly.

    Has he got "Normal" fittings and bulbs?

    You could be right, he has 4 bulbs running from the same dimmer and wants to make it 6 (3 bulbs on each light fitting). Could this be enough to blow it?

    What do you mean about the lights being mains and not transformed? And being the same?

    Not sure what you mean by normal? He currently has one bulb on it's own and 3 bulbs on the other fitting in a 3 way light thing. The dimmer is pretty normal I think.

    Nope, standard bad boy energy sucking bulbs. Dimmer worked fine before the second light added.

    then u have overloaded the dimmer

    Changer the dimmer switch for a 2gang dimmer switch as if it was origanally a 1 light room the switch will be a 1 gang. Depending on how flash you want ur switch should only cost £5-£10 unless you want brass plate effect ect

    Mine has a limit of 150 w . Two 100w?



    Think he was putting 240W through it, going up to 360W when he adds the other bulbs. Can you get one that powerful?

    Does that allow you to control them independantly? That would require extra cables being run down to the dimmer wouldn't it? He wants to avoid that if possible. Is there an easy way to get extra cables down there?

    Did your dad touch the dimmer switch, or did he just work on the lights?
    Does the dimmer now work if you take the added bulbs out?

    Didn't touch the dimmer switch, just the wires above it.

    Haven't tried taking the new bulb out, might give that a try, could a bulb being in there cause a problem?

    I'm assuming here that the dimmer switch is on the wall and the lights are on the ceiling.
    You say your dad didn't touch the dimmer switch,just the wires above it.

    Can you explain from start to finish in great detail exactly what was done.
    Have you taken the new bulb out yet and tried it?
    What happens?

    Never assume, it makes an ass out of u n me, but in this case you're right, dimmer on the wall, lights on the ceiling as standard.

    Don't have a clue what he's done, just wondering if anyone knew an obvious mistake that would make the dimmer not work or knew how to wire them up and could post a diagram.

    Not tried it with the bulb out but it's at my dad's house and he's at work.

    I think he's going to try a different dimmer, is there one that's rated to at least 360W?

    Yes would allow indipendent use if you got that type or could be single switch so does both at same time, im guessing by ur comment that ur dad has just added the light mid way down the existing cable that leads to the dimmer? if so prob overloading so i would think that a higher wattage would be sufficent or you could just lower the bulb wattage as well. hope this helps
