    Can it be 8,4-18 volts as shown here; http://www.dx.com/p/singfire-sf-826-7-x-cree-xm-l-u2-5600lm-5-mode-bike-front-light-black-red-8-x-18650-317565#.VNMfRYGJerU

    Mostly these lamps arent that high, could it be right, does anyone know?

    There are some wide voltage range drivers, such as sku.26110, so it's possible. Whether or not this one really is, is anyone's guess unless someone has measured it.
    NO! I don't know why DX screwed up the site so badly.
    Ask them.

    Someone will have to open it up and do a circuit analysis, but it's possible with the correct component choices.
    What's up with the scrubbed LED driver IC markings?
    What are they trying to hide?
