I think this is an interesting product but is ridiculous at the same time
It looks like you can't hold your head up when you walk on a trail. You have to hold your head slightly down otherwise you get a spot beam and can't see where you are walking. In the photos they magically have local light when the hiker holds his head up but it doesn't appear to come from the headlamp.
It seems to be optimized for a high level of brightness in general because "that's what you need at night"?
Why is it better to have to charge your battery with a computer (USB)? This will be as annoying as my cell phone trying to guess what word I'm starting to text so it can "help" me out.
It looks like every time you move your head up or down the light will be changing...flood..no spot...no flood. Annoying.
It's like the keyless door lock pads on some cars a few years ago. It's a solution in search of a problem. It's much better to have intuitive manual control of more variables...easy to switch from spot to flood or to have both with variable output adjustment.
It satisfies a certain gearhead desire I'll admit but programming and charging on a computer rather than having intuitive options on the unit itself would be a nonstarter for me.
The real purpose in all the gadgetry is to justify a higher price/profit margin and to push Petzl software across the entire product line.
The closest legitimate use for this technology is adventure running (or whatever it's called) however I think it would be annoying even for that.
Could not have said it better myself
