I'm going to have my ceiling opened up and I'm going to pay an electrician to add lights. While doing this I also want to run speaker wire and ethernet. 1. How far apart should the speaker wire and electrical be? 2. What gauge speaker wire should I look for when sending it over a long distance? 3. I need to buy lots of LED lights (maybe about 120-150) to replace 50w incandescent and MR16(I think that is the right one). Can someone recommend a good brand and a place to but them in bulk? Thanks!
