^^^ whs its called the Alpkit Gamma, it has 3 main led settings, and 3 additional ones. Let me explain. If you hold the button in, it goes to camping mode, and you have 3 less for this. A night vision one, in green, so you can read comfortably without the glare from the page, you have a red night vision one, for doing stuff, and a white one, for more clarity, but very small. Cost about £20, oh, and as said, it has a small independantly switched red led on the rear batterry pack. NOT for rechargable batteries tho, as being slightly larger, they break the case. I google everywhere for a head torch, and this came up favourite amongst fell runners and the like. So impressed, was I, bought a spare one, I did.
Alpkit do others as well.
