I've done a quick search and can't find the answer to my question, so If I may, I will pick your collective brains. Now before we start I am not thinking of doing this myself I just want an idea so I know if the professional I get in is 'ripping me off' or not. I have just had some decking built at the end of the garden and it is quite dark down there so we want some lighting. As we won't be sitting out there all the time is it possible to link 2 lights(thinking modern post type lights) to each other then to a waterproof connector which in turn just goes to a plug inside the house so we can dismantle it whenever we want, and know that there is no power going there. Second part if it is do-able would I need an electrician or could I just plug it into an RCB socket ? Cheers in advance
