1. An electrical lamp comprising:

  • a plurality of fluorescent bulbs arranged in a circle and mounted to an illumination socket, the fluorescent bulbs emitting illumination light when supplied with electrical power;

    a plurality of light emitting diode boards;

    a plurality of light emitting diodes, each of the plurality of light emitting diodes connected to a respective wire extending from a corresponding one of the plurality of light emitting diode boards, the plurality of light emitting diodes and wires being arranged in vertical groups on the light emitting diode boards, and the plurality of light emitting diodes emitting light of different colors when supplied with electrical power;

    a base on which the illumination socket and the light emitting diode boards are mounted such that the vertical groups of light emitting diodes are positioned between adjacent fluorescent bulbs;

    a first electrical circuit connected to supply electrical power to the fluorescent bulbs mounted in the illumination socket for causing the fluorescent bulbs to emit illuminating light;

    a second electrical circuit connected to supply electrical power to the light emitting diodes for causing the light emitting diodes to emit light of different colors;

    a switch for selectively switching the application of electrical power between the first electrical circuit and the second electrical circuit;

    a user interface provided adjacent to the bottom of the base; and

    a programmable circuit connected to the second electrical circuit and configured to adjust the intensities of the light of different colors according to a predetermined program indicated by the user interface,wherein the plurality of light emitting diode boards are mounted to the base and within the circle of fluorescent bulbs such that the vertical groups of light emitting diodes are positioned between adjacent fluorescent bulbs.
