Hello can i spur off a loft light? an electrician put a loft light in for me he did a good job but only put one in,can i spur off the back of the light fitting he put in and run it to the other end of the loft so as i flick the light switch in the loft they will both come on.I have got some 1.5 lighting wire plus the same light fitting i know how to spur just want to know if it will be safe.Thanks for any info
