    I have a new block wall and new driveway going in.

    I expect to put some form of LED down lighters fixed near the top of the wall. The wall is around 2m high.

    I've got individual runs of 1.5mm 3core SWA running to the light positions on the wall.

    The block wall will be rendered and I expect to chase out channels beforehand for the cables to go up to the top.

    What would you recommend at the top? Something like this? with appropriate gland for the SWA, and the lamp connecting into the box?


    Or just have the SWA sticking out of the wall and connected directly into the lamp. Assuming the lamp can gland SWA directly.

    Or run a conduit or trunking up the wall and put the SWA through that? Best flexibility.

    Or mount the box at the bottom of the wall, terminate the SWA, and run flex in conduit up to the lamp?

    The driveway will be block paving, so I can always get back under it if necessary. I won't want to be messing with the wall though, so think conduit might be a good idea just in case I need to change the cable.

    Any other recommendations?

    I've had 2 electricians come to quote, but not committed to one yet. Both have said they're happy to work with me to terminate and/or test with me doing the cable runs.

    If you can terminate the SWA directly into the light then that would be my prefered option, the few terminations (especially outside) the less likely it will fail in the future.
