Hello

[bright spark 50]

I have been lurking for a while and decided will start off small with eaves and gutter and a couple of garden displays and hopefully build from that, a couple of questions 5V or 12V instinct tells me to go with 12V but reading that is less efficient, also plugs and sockets there are that many out there even on the sites recommended in the 101 manual any advice would be greatly appreciated.
