The 2009A MicroPuck is a versatile, compact solution for powering (1) High-Power LED from low DC voltages. The 2009A was designed to power (1) High-Power LED, or strings of 5mm (T 1-3/4) LEDs, efficiently and with stability. This driver provides maximum illumination to the LED while still mimicking the light drop-off of an incandescent bulb, which dims as the batteries are used up.
