Tim, have you tried the standard 3000K 45 degree lamp for tree mounted downlighting? That is my go-to standard for properties that enjoy full darkness. I find that the the 2x lamps are simply too bright for this application. You will get a more subtle effect, less spill between locations and less reflection that provides ambient light. If I were mounting at 45 feet and higher I would probably go with the 2x, but at our standard 30' the 240 Lumen lamps are just the bomb. Regards.
