An apparatus, including a light emitting device, including a plurality of sets of light emitting diodes, and further including a control device for controlling a light intensity of each light emitting diode of the plurality of sets of light emitting diodes is presented. Each set of the plurality of sets may be controlled by a driver. Each driver of each set of the plurality of sets may be configured to control an intensity of light emitted by each set of the plurality of sets. The control device may be programmed by a computer program to control light intensity of each set light emitting diodes of the plurality of sets of light emitting diodes based on light intensity requirements of vegetation that may be stored in the adjustment potentiometers or in the on-board computer memory via network connection or direct plugin modules.
