1. A method for optimizing an LED lighting system cost, said method comprising steps of:

  • determining a first LED cost and a second LED cost, respectively associated with selecting a first LED quantity and a second LED quantity, said second LED quantity exceeding said first LED quantity;

    determining a first power source cost and second power source cost, respectively associated with supplying a first power to said first LED quantity and a second power to said second LED quantity;

    determining a first total cost and a second total cost including, respectively, said first LED cost and said first power source cost, and said second LED cost and said second power source cost; and

    identifying as an optimal quantity of LEDs said first LED quantity if said first total cost is lower than said second total cost, and said second LED quantity if said second total cost is lower than said first total cost;

    wherein a first luminous efficiency associated with operating said first LED quantity and a second luminous efficiency associated with operating said second LED quantity are considered in determining at least one of said first and second LED costs, said first and second power source costs, and said first and second total costs.
