Each lights has a 1w fixed soft-tone LED in a stainless steel 30mm diameter surround. In order to install the lights a hole of 22mm wide will need to be drilled for each light. The cable is 10m in length, with a 5.5m lead from the socket, the individual sockets for the spotlights are at 0.5m intervals along the remainder of the cable.
