I'm hoping someone can clarify something about the use of a buck for me.

http://ledmuseum.home.att.net/acronyms.htm defines a buck as A circuit that drops the voltage down so the LED doesn't get smoked

So, if I have a buck with the following specs:

Absolute Max Ratings
Input Voltage, DC 25V
Output Voltage 25V

Typical Characteristics
Input Voltage Min 5V

Specifications
Output Current 350mA

Theoretically, I can feed this buck 2 123's, in series, for an estimated 6.6V and the buck will work it's magic so a Lux I (Vmin 2.79, Vmax 3.99, @ 350mA) won't go poof?
