...però non ho capito come la torcia valuti il cambiamento di output - automatico ? -

Questo l'ho estrapolato da Candlepowerforum:
I was browsing around the SureFire website and noticed they had added the new P2X Fury with Intellibeam.
I saw a couple of these at SHOT Show and they are pretty slick. Basically there are able to measure the amount of light being reflected back and can drop output accordingly to reduce glare to the user. In the samples I saw, this was accomplished via a small tube that stuck through the reflector and reached out to the lens.
During a media demo the SureFire rep turned the light on and walked toward a wall about 15 feet away. Even though he approached within a few inches of the wall, the beam reflected off the wall remained constant. This feature is not unique but it's the smoothest version I have observed so far. Constant output is also available for times the dimming feature is not needed or desired.
Quindi ha un sensore che calcola la luce riflessa.
E' scritto che la lampada frontale Petzl Nao utilizza una tecnologia simile.
Qui una piccola dimostrazione:

possibile che pur facendo batterie di buona qualità (parere emerso qui sul forum) scrivano certe cose? Mi riferisco al tiro portentoso! 
.....penso abbiano fatto un semplice errore di calcolo..
