I was sitting on a bench near a Wendy's waiting for darkness to aim lights, and staring at a typical incredible live oak tree. I had it figured out in my head, anyone with experience with these things please let me know. There are layers or tiers of canopies, with open and long horizontal meandering branches, and I figure if I had climbing gear, rather than uplighting from the ground, I could downlight lower branches using positions directly above them, on the upper branches. Typical old oaks have at least three main tiers. The other choice is to up light from the lower branches, and then the final choice is to combine. The best thing is that for downlighting, there are tons of opportunities for positioning of zero degree angles. Anyone doing this please let me know, plus info on fixture and wattage of bulbs would be great, too. I hate the effect the EC's use, up lighting from lower branches, near the main trunk, using unshielded mega floods. Another thing I see is people downlighting, but aiming the fixtures toward things other than the tree (which is fine, if that's the objective, but they are not illuminating the tree itself). I found technical tree climbing starter kits by googling the subject. Prices range from 350 to 650, complete with training manuals. Now, in addition to the oak info, if anyone climbs trees this way, please chime in. There are options for double rope or single rope techniques using ascenders, etc. I could use the feedback.
