A light emitting diode lamp that operates directly from an AC input. The lamp has an even number of light emitting diodes that are disposed on a cylindrical cluster plate. The diodes are separated into two halves that are conductable in opposite electrical directions. The two halves of diodes are connected at two terminals. The diodes are arranged in a circular configuration near the edge of the circular cluster plate. Leads are connected to the terminals. The leads extend toward the center of the circular configuration and extend through the cluster plate. A modifying resistor is connected between one lead and an end terminal of a lamp housing. The other lead is connected to a base terminal of the lamp housing.
