More Info

The ARRI 2.5/4KW High Speed Electronic Ballast with ALF 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 1000 Hz rather than the typical 50 to 200 Hz 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.

Flicker-free light up to 5000 fps
When combined with an adequate HMI lamp, at least 5 times more light output than a tungsten light of the same power
Light intensity increased by at least 5%
Constant lamp power
Constant color temperature

Control of electric power of the lamp between 50 and 100%
Variation in power supply voltage of 10% has no influence on the power of the lamp
The ballast is built into a casing with IP21 or IP22 protection
