Actually each string is about 14 feet of lights. Not sure where you got 9 feet. That is a 20’ ramp, top hand rails are 16’ , I took 2 of the sets I got last week and put them along the 2x4 at the top of the lattice on either side and the light up the ramp nicely, 1st light is at the 4x4 at the top, last light is at the bottom facing out towards the driveway.
I don’t know about a tree, but I have them mounted facing down along the fascia of my porch, and they are bring enough to light up the porch. Ignore the forward facing LED strips. Those are Taotonic strips, but you can see the garden spots facing down . Not the best pic, but the easiest one to grab at the moment . I won’t be home until Wed. If you look for the thread on these actual lights, not this sale there are some better pics by others
