If the claim of 3600 lumens is accurate, light output down-the-road should be more than adequate. Due to the vague cut-off, you may need to lower the beam to keep oncoming traffic from flashing their lights at you.
Yes you have it right. You re-use the rubber boot and the bulb adapter.

The stock retaining wire is removed and is replaced by that metal strip which provides the spring tension on the outside of the rubber boot. The stock wire/spring is under the rubber boot and wouldn't work in this application.

i just came back from a motorcycle rally in Laconia NH. The lighted road area is just fine and I didn't get anyone flashing their high beams at me.
