1000mA BuckPuck LED driver.
These are used in place of a resistor and are much more efficient.
Min input voltage is 5v.
Max input voltage is 32v.
This 1000mA version will provide the correct mA for most Luxeon III LED's or any LED requiring 1000mA.
The driver can easily power multiple LED's as long as you provide enough voltage.
IE.. you need around 5v for one white Lux III, 8V for two white Lux III, 12v for three etc..
The REF and CTL wire leads can be used to attach a linear taper potentiometer so that you can adjust the brightness.
