I have always used Stainless Steel Hanger Bolts to mount my downlights into trees. A few manufacturers offer different versions of EPDM rubber tree straps for mounting. I have always wondered about the convenience and reliability of these strap mounts. Have any of you used rubber tree strap mounts? If so what is your opinion of them? How does the rubber strap stand up to time, weather and UV Rays? Do you find these easy to install onto large, old trees? Have a great day.
