Larry, did not watch the link. When I got my Nondestructive Testing ratings, kind of had to know a bit about that and more. Thankfully, I left that job in the mid 90s, got my fill of being in a black light controlled room, inspecting flight critical components.

No doubt what you linked is valid for folks purchasing LED headlight bulb assemblies. I learned long ago, heat dissipation is super critical to maintaining the rated output and longevity. The two headlights, and two oem fog lights, converted to driving lights all run forced air fan cooling. At the time I installed them, others here assured me the fans would fail. As of yet, that has not happened.
