No objections to any of that, other than that if the tree grows very fast and the homeowner forgets about it, it may cause more trouble than my way. When it reaches the first nut, the bark has already engulfed the hex part of the bolt. So the bolt cannot be backed out, and the light would need to be rehung on new bolts. Depending on the tree, this could happen many decades later, or just a few years later.

So... Oh, well! If it's completely engulfed by new growth, it won't be a problem for the tree.
It might become a problem for the poor sap who runs that lumber through a surface planer 100 years from now.
I looked pretty closely at the stuff in Williamsburg. Almost without exception, it's not hanger bolts, it's lag bolts. I suspect they just check them periodically for "engulfment", and adjust them. All in all, that wouldn't be too often per tree. They'd just have to have a PM schedule.

Yes, but the new bolts will require new penetrations, each with a small but non-zero risk of injury to the tree.
Yes. I think that's the decision point for the OP. If scheduled PM is the norm, go for lag bolts. If set-it-and-forget-it is more the norm, go for hanger bolts. Given these lights will be 20 feet up, I'd favor hanger bolts (long ones).

Really? Then my yard light must be staying at the same height and the yard is sinking!
Coool!!!

Heh, perhaps a repair that fixed what wadn't broke......
rcm is far from an irrelevant newsgroup. ahr would be well served crossposting a variety of content over there, as that group has a most inneresting blend of a wide variety of pro's, diy-ers, and just generally smart problem solvers. Many on rcm will know more about certain specifics of a problem than yer fav contractor, altho they might not have the same overall skill level over the completed job.
AND, if for some reason the thread IS hijacked, most often it will be a very intelligent hijack. :)
Not knockin yer intent, just sayin said intent may have been a little misplaced here.
AND, not sayin rcm is "better" than ahr -- each has slightly different and most often very useful perspectives converging on a problem.
Its those California Trees ... too much LDS in the sixties.

So did the mormons.... Look at Christopher.... you think alladats just from poor diet/fitness, bad air and a li'l escaping freon/??
Or you're shrinking like I am. I'm about an inch shorter now than I was in my 20's. Art
Which part of your body? 8-)

Left myself wide open for that one! An inch shorter in height. I suspect the discs in my spine are compressing as I get older. Art
Or you stopped wearing high heels. ;-)
Some trees appreciate metal. This one fell in love, and won't give it up.
Ya but, your ears are bigger and your nose is longer. 8-) Oh yea, I forgot, your farts are louder.

Not me, James Tiberias Kirk.
After 2 back surgeries Im about an inch shorter myself.
But that yard light is now about 14" higher then where I put it.
Damn..subsidence is insidious isnt it?

OK, screws it will be. Altho lag bolts sort of make me cringe. I'll try SS deck screws.
A mildly inneresting corollary to the tree growth issue is that if screwing, the screws should be in a straight axial line along the trunk, with no radial variation.
Appreciate all the great input -- from both rcm-ers and ahr-ers -- ping Una.... :)
On using lag screws- you could use long lag bolts with machine threaded ends, and leave a few inches sticking out of the tree. Attach the box etc to the screw ends with nuts under/over and make sure the box is also several inches from the tree.
It will take years for the tree to fill the gap between the screws and the mount. You could even move the mounts out with female threaded standoffs after those years go by.
