cherry-picked hank-lume-x1 code from https://github.com/loneoceans/anduril/commit/d83ebb75dab8c462b7efa841bccc00a136ff15a2

The [PR](https://github.com/ToyKeeper/anduril/pull/37) has a lot of other
stuff in it, so I'm just picking out the parts needed for this particular
light, and leaving the rest for later.

Will need further edits before merging into trunk.
