just purchase an outside light (50 watt led) I wish to fix to the wall approx 3 metres above an existing outside double socket, my question is..can I run the cable direct down the wall, into one of the top entry points into the socket, the light currently has a plug on the end, I wish to remove the current cable as its ony a short length & add a decent length of new outdoor stuff and run it straight into the box (which is the remote control type of socket), can I then simply wire it in via this way, is this a safe install?
