This is a 90-250 VAC ARRI Electronic 2.5-4K Ballast with ALF. A dual voltage electronic ballast with 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.
Multi-voltage, quiet operation.
Dimmable, operates with 2 or 4K setting.
