This 6,000W Plus Compact HMI Fresnel Light System with 6/12KW ALF & DMX Ballast from Arri includes the 6,000W HMI Compact Fresnel head, barndoors, a filter frame, a 50' head/ballast cable, and an ALF & DMX electronic ballast.
The 6,000W HMI head provides a daylight-balanced spotlight in a compact yet high-efficiency light. It has a beam angle of 15° to 50°. For further control of the light, this system includes barndoors and a filter frame.
The included 6/12KW multi-voltage electronic ballast features Automatic Line Filtering (ALF), which 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.
