Ballast Factor

The percentage of a lamp's rated lumen output that can be expected when operated on a specific commercially available ballast. For example, a ballast with a ballast factor of 0.93 will result in the lamps emitting 93% of their rated lumen output. A ballast with a lower ballast factor results in less light output and also generally consumes less power.

      This ballast has a 2-year warranty from the date of manufacture. Typically, they last longer than two years depending on application, on/off cycles or if the area experiences power surges.
