dat2zip,
Could you state all of the specs for this new Shark Buck? I am very interested in the driver, but I wanted to know the min and max input and output voltages. Is there a maximum current that the Shark Buck can input, and can the output current be tweaked any above 3000mA? It would be neat to use two or three P7s in series operating (with a potentiometer or set resistor values) from an automobile (with proper protection circuitry, obviously). Thanks.

Seven! Whoah, that's 70+ Watts of power (at 3A). The Shark Buck max input voltage is limited to ~25V. You could drive maybe 4 with that voltage. Two drivers one with 4 P7s and one driving three might work.
I hope you have a large heatsink for all those LEDs.

DaFABRICATA,
Yes, that is correct as long as your fresh battery state (worst case) is 25V or less.
(But, That is the IC max voltage rating (25V) and the capacitors voltage rating (25V) and pushing everything to the limits could be trouble. Normally, it would be best to be conservative and operate below absolute max ratings).

I would like to know too!Any word when it will be back in stock?
Wayne, if I attach my old batch Shark Buck to a Shark Sink, will I be okay running 3A?
