I am hoping that the light part of the setup has been updated during the last decade. If not, older LEDs were not as efficient as the newer versions. If needed, I would swap the emitter and the driver. We shall see… another winter project, they keep adding up.

I am not exactly sure what you are saying, but I think you are saying you might try to build a light or re-build a light. Many of the light models change frequently, so I think you would find they are up to date for tech.
I think the current lights out there are plenty adequate, but most of the dynohub powered lights are designed for on-road German standards, a low flat beam for adequate lighting and not wasting light up higher or putting light into oncoming car drivers eyes.
And then there are the lights that have a flashlight beam with a round pattern, which off-road riders may prefer. I am quite happy with the B&M lights that have 70 or more Lux for on-road use or for rail trails. I have B&M dyno powered headlamps on four bikes.
I bought most of my lights from European internet sellers, was quite happy with their pricing. Some of the European sellers have a very high shipping fee for the first item, but additional items do not add to that cost.
