Some tools do their jobs so well they're a little boring to write about. The E75 provides everything most of us could want in a midsize flashlight, and very little we wouldn't.
@solrize Current measurements are in the runtime table. Like I said, I think the output (and therefore efficiency) measurements may be a little optimistic. It does have a boost converter.
I agree a powerbank function would be a great addition here. It would be the perfect larger travel light if it had that. The tailcap magnet is easy to remove.
Additional testing has proven that I cannot accurately measure current with my ammeter in series at 6A, and the actual current with the tailcap installed is probably considerably higher. I have removed that number from the table.
