hi, Im fairly good with electrical work but would like some advise on adding another outside light. We currently have a 500w halogen flood light with built in PIR , supplied by 1.5mm2 twin and earth cable, from a fused light switch, havent traced the cable yet to see where it is fed from, only traced to the switch. What i want to know is, Can another 500w halogen flood light with build in PIR be fed from the same cable, e.g: cable comes from light switch into junction box, 2 cable come from junction box, 1 to one light and 1 to another light? Any advise is welcome. thanks.
