I've tried so many grave lights ... Quite quickly penetrates somehow somewhere the water and the light is gone. I have tried taping, higher posts in the lantern, put on cork etc. Nothing really helped. This light has a complete sheathing - the light is enclosed in a plastic sleeve for screwing - dry! I like that very well and I am assuming that nothing will change with time. Still, I would have a suggestion for improvement - the light is red and the envelope also characterized this light in a lantern rather dark. Perhaps the lamp could be yellow per se or sheath colorless. So that the light would still Schönner. I'm going to order one - showing that I am zufriedn! The settlement went smoothly! In my view, highly recommended!
