Here you got a link to the post already made about it, or maybe you are talking about other llight than Ultrafire T8, if so, please comment which one.

Double lens flashlight with XM-L and big head at kaidomain

I have just seen this one, it says it has two lenses, I haven't seen any other before. http://kaidomain.com/product/details.S020102 I do not see two rings as on a reflex camera zoom where you can adjust the zoom and the focus. I feel even being able to do it, it might have much light losses, but I like the idea at least.
