Can I loop off existing external light

[cress]

Hi all,

I have an external light on side of house that is controlled from a 3 gang switch inside the kitchen, the other 2 switches control the kitchen lights.
I would like to add a 2nd floodlight (probably a 120w halogen lamp)on back of house. Can I take a loop from the terminals on the existing external light with a length of cable around to the new lamp so they both illuminate from the switch in the kitchen??

Yes, use black rubber flex outside.

If you don't want black, look here for suitable cable.

You can extend from the existing light fitting, it's unlikely that you can extend directly from the switch as it more than possible that a neutral will not be available there, but you can loop the neutral and live from the existing light which will mean using the same switch to turn both lights on/off.
It is possible that you could have the second light independently but that configuration would depend on the existing set up.

(probably a 120w halogen lamp)

2 "Nos":

1) A halogen light > 100W

2) A halogen light of any size not on a PIR or photocell.

Working off the same switch is fine as we want both lights to come on with the switch rather than PIR

I presume 1mm 3core cable will do the job for the loop??

Does the wattage of the new lamp need consideration?

It is not fine from a Building Regulations POV.

I thought the cut off point was 150W for outside lights and special controls/efficiency.
