At our campground (we use in the summer), we have LED outdoor pathway
lighting that is run from rechargeable batteries that are charged via
small solar panels on each outdoor light.
I can tell you this, the LED's do a very good job of lighting the
pathway, they are so efficient that the little "AA" batteries power them
all night (up to 12 hours), and what's' really remarkable is that they
do not draw any insects. It's kind's funny because my orange outdoor
bug light has all manner of bugs around it, but each of the white LED
lights have none. ;-)
Have a great weekend!

I'm not the slightest bit surprised that there are some in use right
now.
There was a time when only a small group of a certain type of people had
computers in their homes. Here's to hoping that the timeframe is closer
than my friend and her peers think. :-)
