If you want light and electrics into your cabin then purchasing this lovely Ready Board allows you to simply contact a local electrician and ask for a quote to fit this one item as it has light and electrics built in. It means you don't have to have acres of wires everywhere so it won't take an electrician as long to install, so it's far more cost effective for you!
