... if lighting up like ARRIMAX (18/12KW), I know the power is really large, I don't think there's any portable generator can support it. Is it normally to hire a generator truck for that or any other method to get the power ?
While the power draw of an 18kw ARRIMAX far exceeds the capacity of a portable generator, there is another option. Arri has just combined their MAX reflector technology with a new power class of HMI lamps to make a light that that can be run on portable generators and is as bright as some 18k Fresnels. This new light is the M90.
The light generated by the CAD designed Max Reflector of the new
M90/60 is incredibly bright and sharp.
Pairing a new 9 kW HMI lamp with the MAX reflector of the ARRIMAX, the new ARRI M90 creates diverging parallel rays to produce a crisp light with even distribution through a wide spot/flood range. The result is a lens-less open face fixture with a quality of light close to that of a Fresnel. The elimination of spread lenses like those used on HMI Pars makes the ARRI MAX reflector lamp heads comparable in output to par configurations of a higher wattage. In fact, the M90 is brighter than some 18K Fresnels on the market.
The Active Line Filtration (ALF) of the new ARRI EB 6000/9000 ballast
makes it an incredibly efficient and clean load.
To power the new M90 head, ARRI has engineered a dual wattage ballast (6 & 9kw) with Active Line Filtration (ARRI's system of Power Factor Correction.) The advanced electronics of the ballast makes it incredibly efficient and it generates virtually no harmonic noise.
The combined 100A output of paralleled Honda EU6500s is sufficient to operate
the new Arri M90 as well as additional set lighting.
Drawing only 84 Amps, the M90 can operate on the combined 100A output of paralleled Honda EU6500s. Not only is this approach a lot less expensive than using an 18kw ARRIMAX, it is also a lot easier and offers more versatility. It is a lot easier because you don’t have to tow a diesel generator or run heavy feeder. It is more versatile because when you don't need the punch of a 18kw, you can swap the 9kw globe for a 6kw globe making more power available to run additional lights on the paralleled EU6500s. For example, you save 27 Amps when you swap out a 9kw bulb for a 6kw bulb. The 27 Amps you save by burning the smaller 6kw globe will power quite a few more lights when you consider that both the ARRI L7 LED Fresnel and Kino Flo Parabeam 400 use approximately 2 Amps.
