I talked to the guy who put them up. His name is John Preston and he is a very intelligent and interesting guy. He makes the lights himself and so far has 109 of them spread throughout the trees in his and his neighbors’ lawns. I told him you guys had written a book and might be interested in his garden of lights. He takes alot of pride in them.
They are in glass tubes about one and a half inches thick. They are truly remarkable and I hope you find interest in these. –Brad Sheridan
