I have a light like that but I don't get to hunt hogs enough to use a solar panel just 2 sets of batteries last me .When I bought the same light I paid almost a hundred for the light alone. That's a great set up all self efficient, we hang ours from tripods made from rebar 10 feet high but you are right about the vitals not showing good . We have also used solar driveway lights, cheap and easy , although the light is white they seem to be just as scared of the green as the white lights the first time they come in .
