1. A Light emitting diode compensating circuit comprising:

  • A. a current input electrically coupled to a substantially constant power source;

    B. a plurality of light emitting diodes connected in series, said light emitting diodes being connected to said power source;

    C. a signal input electrically downstream from said light emitting diodes, said signal input being constructed and arranged to transmit a current drop occurring across said light emitting diodes upon exposure to said power source; and

    D. at least one controller comprising processing software and a look-up table having stored data representative of electrical specifications for combinations of light emitting diodes, said controller being constructed and arranged to access said look-up table for identification of at least one current analysis value, said controller in communication with said signal input, said controller being electrically coupled to said current input, said processing software being constructed and arranged to analyze and process said current drop compared to said at least one current analysis value and to adjust power provided to said light emitting diodes.
