I bought this head torch locally to see how the non-focussed output would look in a dark room. It's an interesting effect. Instead of a focussed beam of light in front of you, it's a gentle wash of light over the whole room.
The little six pin chip that controls the LED modes has a slightly vague number that could be A25B or A256.
The button has a 470 ohm pull-up resistor, and the LEDs are driven via two 6.8 ohm resistors in parallel. (3.4 ohms)
