A method for optimizing an LED lighting system cost includes steps of determining LED costs, power source costs, and total costs associated with a plurality of LED quantities, and identifying a lowest total cost as an optimal cost. A LED lighting system includes an LED operated by a constant-current driver at less than its maximum current capacity. A programmable controller including a feedback routine is used to compensate for intensity drift as an LED ages. Other embodiments of LED lighting systems include multiple LEDs producing light having various spectrums to optimize the lighting system efficiency and the effectiveness. A charge controller including an MPPT routine is advantageously employed with a LED lighting system powered by a limited-capacity power source.
