300 lumens? My current headlamp can do that with a single LED. It has both tight- and broad-beam settings. It can be dimmed to save the battery. And it has red LEDs available, too, to spare the night vision and not blind the people I’m camping with when I inevitably need to get up in the night.
So, meh. Happier with what I’ve got.
Now, if you were offering me a self-illuminated water bottle that I could hold up and say, “Aiya Eärendil elenion ancalima!” that would be something!
