lights

[fire]

have installed 4 down lights 11W each 230V, have connected them in paralle but 2 are bright and the other 2 not so bright. do you know why?

For parallel perhaps read series, for 11watt (CFL??) read 9 watt,

dont understand what you mean.

Did you wire them in series by mistake, are the 11 watt actually 9 watt or less

Different batch of lamps? Swap them between fittings, if they miraculously get brighter then it's a wiring problem, if they're the same then it's a lamp problem.

Hi Dunc,
I think what malcolm means is have you got the two that are bright in paralel,
and the two that are dim in series.That would give you the problem that you have got.

all are wired in paralle does the lenght of cable in between lights have anything to do with it?

Not unless youve run it down to the end of the street and back between fittings.

measure the volts at all the fittings,if you read low volts at the ones that are dim,
then measure live at the dim ones and neutral at the bright ones ect,this should help
find the problem.

or... get rid of the cfl crap and install LEDs
