Abstract
A driver and a light fixture including an LED array and the driver. The driver including a microprocessor, at least one capacitor, a charging circuit, and discharging circuit. The charging circuit is controlled by the microprocessor and charges the at least one capacitor to a voltage such as at least two times a forward voltage of the LED array. The discharging circuit is controlled by the microprocessor and delivers power from the at least one capacitor to the LED array in discrete pulses.
