I have a LED spot light that was being run by a 12V 5AH lead acid battery. There was a board that both charged the battery and powered the lights through a PT4115 LED driver. Near as I can figure from the sensing resistors, it was supplying 606ma to the light.
The light has 36 large LEDs. There are 12 rows in parallel of 3 LEDs in series. I don't know anything else about the LEDs.
The board has since fried. I though I would resurrect the parts and pieces and build my own solar lighting system.
What us the most efficient off the shelf driver I can use for this light? I would really rather have an off the shelf pre built driver like a buck puck. I don't really want to build up a regulator from the chip level if I can avoid it.
