    Hello,
    I am putting in my sprinklers (thanks to all the help on that).

    I want to put in at the same time as I have trenches open wire for spot lighting.

    I am not ready to put the lighting in yet, heck I haven't had a chance to design anything out in that respect yet.

    I know I am mostly looking for some scalability. I know I will want at least 8 spot lights, maybe a few more. I am guessing I will need a fairly high powered transformer, like 300W.

    I know the longest part of the run is going to be up to 275 feet and then there may be some lateral lines at 20-30 feet each.

    Would it make sense to go with a 12 gauge wire at this stage?
    Is one wire enough?


    Thanks

    So been studying this more.

    Seems like we will want 8 tree lights, 2 central lights and some driveway spot lights. So I will come up with a design and repost question.

    Use the sites search engine for lighting calculators. Some of the manufacturers have them available at no cost.

    Here is a plan I have put together

    I am now assuming I will need two transformers

    My main concerns are

    1) On the more extensive run, my wire is going to go something like 350FT+, I am not sure what gauge wire to use
    2) I don't know what size wattage each light will have, if I go LED I assume it will be much less.

    I will definitely do a search like you suggested

    One thing I have figured out is that my total wattage requirements Shouldn't exceed 100w per transformer so if I assume 150w transformer I think I will have plenty

    This is predicated on the assumption I go all LED which I plan to do.

    I am basing this on the Malibu stuff at Home Depot

    Try posting these question's in the landscape lighting forum. Those guy's know what they are doing.
