First, a little history...
Last Spring I bought a box of 10 sun powered lights. They are also copper plated. I like them. The glass lenses that help protect the white LEDs are faceted, so the light radiates across the ground like a person might draw the rays of a sun. When spaced about 8 feet apart (I'm guessing), they provide enough light that I can find my way. I have 2 problems with these lights: 1) the earwigs love to do whatever they do inside the glass lenses and inside the tubes that stick in the ground (where they get in, I think), 2) it has been a dry 6 months, but the copper plating is already weathering away. They're not getting a patina. It just looks like it was cleaned abrasively with a scouring pad.
Fast forward...
A month ago, I bought 6 of these sun powered lanterns. I really like these. I didn't realize it when I purchased them, but light radiating from these is completely different than the others. The orange(?) LED flickers and lights up a piece of plastic that looks like a candle. As simple electronics go, I'd say it is very realistic. They stand about 3 feet tall on the hook. They do not put out as much light as the others, and they do seem to lose their strength as the battery loses energy. Even with the lost energy, they manage to flicker all summer night and into the morning. Last night they went on sometime between 7 and 8pm, and were still going at 6am this morning.
I have 2 problems with the lanterns as well: 1) the hooks come in 3 pieces, which seem to be made independently of each other. The hook and stake portions look and feel like solid copper, but the piece connecting them looks and feels like copper plated aluminum, and I worry that the 3 portions will weather differently, 2) 1 of the 6 lanterns stopped working; probably the connection to the battery has come loose.
It will be interesting to see which bugs take up residence in these lanterns, and how long the copper plating will last, but I would, and probably will, buy them again.
