The 120-220 VAC Arri 400/575W Electronic Ballast with ALF is a dual voltage electronic ballast for the Pocket Par 400 HMI light, and features an Active Line Filter for Power Factor Correction. ALF provides a higher Power Factor resulting in more efficient power use. This is accomplished by shifting the voltage and current waveforms in phase and minimizing harmonics and spikes. ALF also minimizes the current carried back on the neutral leg of the power systems.
- Quiet and dimmable, perfect for video or motion picture use.
