Thanks for this thread: I found it while looking for info about the Flare. That's unfortunate about it not storing flat: I wondered about that from looking at the picture. I wonder if it's feasible to replace the headstrap with a plain bit of elastic.

I don't understand why there are so few ultracompact headlamps: they are basically just keychain lights on a strap, right? The hassle is that the head has to point forward and most keychain lights aren't made that way.

The e+LITE seems nice but is way expensive, the Flare somewhat more affordable, but now that we all have tons of Covid facemasks around, maybe I can repurpose the elastic from one to turn a Photon-style microlight into a headlamp, using a bit of plastic packaging material as a backing plate. I'll post a pic if I manage to do this.

Added: any idea how well these things work, as an alternative to an actual headlamp? It's just a headband with a holder for a small AAA light on the side of your head:

Maybe I can make something like it that's even lighter, intended to hold just a 1aaa light. The Niteize one is fairly beefy so it can hold e.g. a 2aa Minimag.
