Electronic Ballast Characteristics
| General Definitions | |
| Power Factor: | Measure of how effectively ballast converts power source into usable watts. Ideal power factor would measure 1.0. |
| Crest Factor: | Measure specifying the ratio of peak current to R.M.S. current in the waveform used to drive rapid start lamps. High crest factors shorten lamp life. |
| Total Harmonic Distortion: | Measure of magnitude of input current harmonics compared with amplitude of fundamental frequency current. |
| Ballast Factor: | Lamp manufacturers publish lumen data based upon a "reference ballast" built to meet ANSI standards. Ballast Factor is a measure of how well a ballast performs in comparison to the "reference ballast." |
