The lights are to be run off a 12 volt 110 amp leisure battery during the night,the battery will then be charged up during the day. each light will carry a 10 watt bulb.

10 x 10 watt = 100 watts 100/12 =8.5 amps. So you will need two core cable with at least 8.5 amps capacity. Depending on the length of the run you will also have to compensate for votage drop, in ten steps! Additionally a 12 volt fully charged battery will put out about 13.5 volts which will over-run the lamps and give them a VERY short life. The low load will not cause enough voltage drop at the battery. You would also be better to use two or three runs of cable to minimise load and voltage drop effect. Overall I dont think your idea will be a success. sorry!!
Ignore the reference above to earthing, this is not a requirement with low voltage.

would desire to do with greater info, e.g is it outdoors? what's the max load? no rely if that's outdoors, you will desire to guard it say in duct and that i'd used armoured cable. without understanding greater, i'd recommend 2.5mm T&E with an RCD on the source and yet another on the termination earlier splitting it into lights and power sockets. Your load is constrained by utilising the source 'fuse' that would desire to be rated decrease than the 'weakest' cable score. Voltage drop would be you considerable problem, doubling i.e. 2 x 2.5 T&E would help (and prob Ceaper!) while you're uk based, watch the recent electric policies and regs, you will desire to locate youself in worry in the adventure that your no longer qualified!

you should use regular wiring that is used for inside houses..
just make sure you have a good path to ground ,
on the third wire.
