Try low voltage garden lights. I did the solar/ led thing and they were just not bright enough to be useful I am installing lights on out horse shed and coral. Not finished yet but I an very happy with the half I have installed 200 watt low voltage transformer. $19 outdoor remote control $9 spot lights with 20 watt halogen. If using long runs or lots of lights, remove halogen and use 6 watt LED spots. Much better than anything else. Almost as good as 120 volt. Instalation is much easier that 120 v and you can easily change it. The remote is also great if you light the pathway too. See what is out there before even going out. Push the "clicker" button and the lights come on. No great electrical knowlege needed if you have a convienent AC outlet on the outside of the house. I have done a lot of county approved AC work. But for a wood shed or horse area why bother with deep trenches, expensive wire. junction boxes and conduit.
