Power factor is an important criteria to consider when evaluating LED lighting installations. Power factor is defined as the ratio of real power to apparent power; in other words, it is a way to determine how much of the current contributes to real power in the load. Power factors for electrical systems are a number between 0 and 1. A load with a 1.0 power factor requires the absolute minimum amount of current, which is a good measure of efficiency.
