ARRI 12K Fresnel:
The ARRI 12K Fresnel HMI System features a powerful HMI lamp head with a 24.5″ Fresnel lens, a 12/18kW electronic ballast with Active Line Filter and DMX support, four-leaf barndoors, filter frame, and a 50′ head to ballast cable. The daylight-balanced lamp is capable of outputting up to 18,000 watts and work from 190-250 VAC with the use of the ballast. The Active Line Filter 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. The ALF also minimizes the current carried back on the neutral leg of the power systems. Included with the light are a four leaf barndoor set and a filter frame for modifying light as well as a 50′ head to ballast cable. The Daylight range of studio Fresnels using Double-Ended HMI daylight lamps has been the mainstay of the film industry for many years. Arri HMI Spotlights have the largest lenses in their class and extremely even light distribution. When fitted with an 18K HMI bulb, this HMI Fresnel will turn night into day with 1446 footcandles 13 feet in diameter, from a distance of 66 feet @ full spot. It will throw 167 footcandles 101 feet in diameter from the same distance, @ full flood.
