Security Lights on house - what wire?

    I'm replacing a 600watt security light on the outside of the house with a 400watt light and adding another around the corner of the house, meaning I'll have to run a cable around 6/7m round the corner.

    I plan to replace the existing one and just branch off that for the next one, but don't know what cable to use and how best to attach it to the wall (brick and mortar.

    Any suggestions?

    T&E cable is the way its been done for years (to god effect) however for outdoor use the UV degrades the insulation and water can get in and start being a pain. i would recommend using a flex type cable with rubber being best.


    I would also se LED lights to save a packet in power usage!

    flexible cable shouldnt be used for fixed wiring over a distance apart from a short tail from a waterproof box to the light fitting. by rights it could be wired in grey twin and earth in a conduit or armoured cable . both look a mess on a private house :(wiring it in flat grey clipped looks the neatest but isnt uv stable but would last donkeys years anyway .

    Argh!!! These terms are confusing me!

    So 1mm twin and earth should be up to the task, just that the UV de-grades the wire over time...

    Whats the best solution for glipping it to the brick/mortar wall? I've used little rawl plugs internally with normal 'beam clips' in my workshop, is that the best option?

    if u use decent clips they should go in the mortar if its not like concrete. if its soft and clips fall out or either just shape some wooden plugs and hammer them in and snap em off ;)

    As I said that's how it has been done for years but the regs draw attention to the uv issue

    its a very tough cable,performs and costs somewhere between pvc/pvc and armoured.
    easy to clip in neat runs,harder for rats to chew through.very common here for external walls,and surface garage installs
