An apparatus and method of operation of a low-current LED lighting circuit are disclosed. The invention utilizes high AC voltage input and unreduced voltage ripple component of the rectified DC power signal, which provides the ability to drive an LED load at high power factor at low current. The invention discloses both active and passive circuits to limit the peak current flowing to the LED and create a current source for the LED load. The proposed circuit increases reliability by optionally eliminating capacitor, inductor, and heatsink components while minimizing luminous flux fluctuations.
