I have several dozen cheapie dollar store and discount store ones... they work for a limited time only... until... until you replace the cheap-shit battery they come with, with a decent one! I have them stuck all over my yard in the summer, and come winter, I pull the batteries, store them indoors, and pack the lights in a box outside. when the ground thaws.... out they go.

I am going to try to make some hangers for them to hang from trees, to light up some trails, and I don't have to move them when I go through with the lawnmower/quad/sled.
