I’m not going to be able to do a run time test but regarding 3 AAA batteries…yes, I agree, it is what it is. For hiking, I’m less interested in how bright it can be and for how long and more interested in how low I can adjust it and for how long. The ability to just tap the side and have it go to full brightness and then back to the memory setting with another tap is very useful for me.
I have Zebralights as well but I have them in AA, again just because it’s convenient and lighter weight.
If I was into running at night or caving where I need a light that’s bright for a long time then I would be using 18650’s and waist mounted battery packs.
For a $35 general purpose hiking/camping headlamp, the user interface on this one is pretty convenient. When I have a project around the house that requires light to see detail, I put on my reading glasses and go with a Zebralight.
I’ll use the BD Spot if I pull out my telescope, go hiking or camping.
I’ve been away from the site for a few years so I’m catching up on what’s new now. 
I haven’t noticed any PWM or flickering. The beam is pretty free of any artifacts as well. I put a piece of adhesive diffusion material in front of my last BD Storm. I don’t need to do that with the Spot.
