Driver question

http://intl-outdoor.com/ld2c-3a-12-cell-circuit-board-p-732.html

Anyone have experience with this driver ?
How does this detect if your using 1 or 2 cells or do you have to set it up for one or the other. Little solder ?
The description on the site doesn’t really tell me.
Is this considered a buck driver ?
Thanks

With 2 cells and a 3 volt led it would be considered a buck driver.
