Product Highlights
  • Photography At Up to 5000 FPS
  • For 2.5/4KW HMI Fixtures

The ARRI 2.5/4KW High Speed Electronic Ballast With ALF (1000Hz) is designed for use with ARRI 2500W or 4000W HMI luminaries for high-speed photography at 500 to 5000 frames per second The ballast operates 1000Hz rather than the typical 50 to 200Hz and incorporates ALF (Active Line Filter). 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 infrastructure.
