What is the power factor of a LED driver?

The power factor is a measurement of how much energy is converted to useful power in the LED driver. It is a number between 0 and 1. If the power factor is 0, the driver is not using any of the incoming electricity. If the power factor is 1, the driver is using 100% of the electricity it is receiving. Most customers want a power factor greater than .9. Please check the individual specifications for the power factor of each driver.
