In the original post, esthetically pleasing, was part of the dialogue. This in my mind precludes international orange guy-lines...
The problem with the small LED lights is that they have to have sun and most of the camp sites we use have trees. I remember seeing some one at one of the Tearjerkers gatherings with a bunch of them sitting in the sun away from their camp site. I suppose that this is nit picking a bit but we like to star gaze and light pollution from camp fires or heaven forbid Coleman lanterns makes that more difficult.
