4.Technical terms on electronic ballast
1.PF（Power Factor）
The ballast Power Factor is the measurement of how effectively it converts the voltage and current supplied by the power source into watts of usable power delivered to the ballast.
Power factor=True power/Apparent power
The higher the power factor is means the more electrical power you utilize. The PF of electronic ballast can achieve over 0.9, even 0.99.
2.THD（Total Harmonic Distortion）
Total Harmonic Distortion: Total harmonic distortion (THD) measures the degree to which the current wave shape is distorted from a sinusoidal wave, expressed as a percentage.
3. Ballast Frequency
The frequency at which the ballast operates the lamp, measured in Hertz (Hz) or kilohertz (KHz).
