>Going up to Artic Circle to shoot doc filming in tents and/or igloos any suggestions re portable geni‘s?

>Small tungsten and HMI kit hiring from Canada.

>Shooting HD Sony 730s (50i)for European market any issues re flicker or frame rates? is Canada 60hz? Volts?

>Your equipment supplier can give you all those details.

>Typically, in Canada you'll get 120V/60Hz.

>IMHO, flicker-free HMI's are NOT a smart solution for this issue in Arctic conditions. Magnetic ballasts are much more reliable in the cold.

>Why not just bring what you need? It's not like the Arctic Circle is all that close to anywhere metropolitan (equipment suppliers) in Canada...

>When are you going?

>Unless you have a crystal controlled "inverter" generator, I would think magnetic ballasts will flicker. These generators also have the highest power to rate ratio of any type.

>From discussions on alt.energy.homepower, it appears that Honda inverter type generators have reliability problems, while Yamahas are praised.

>The Yamaha YG2800i weighs 66 lbs, and has continuous output of 2500 watts. Output is a crystal controlled electronically generated sinewave, so the stability of a mechanical governor is not an issue.

>That sounds like a sweet geni although the specs don't indicate a 220/240v load. More info may be needed for larger than 1200w applications. The illustration seems to show a 220v receptacle.

>I'd be curious if anyone has tried to strike either a magnetic or flicker free 2500 ballast on one. HMI's draw a bit more amperage than loads for incandescent lights especially on ignition. So this geni may require a two pole 15A breaker to accommodate a 2500 ballast.

>BTW - the Arri specs for the conventional ballast model 2500EBB located here :

>http://www.arri.de/prod/lighting/ballast/eb/eb575-25.htm

>seem to indicate the ballast operates reliably at -20C to +50C and requires 15A 230V AC input.

>I would certainly do a test/check out any geni/HMI combo for operation and compatibility before I travelled to a distant location. Carry extra adaptors, fuses...

>It is strictly 120 volts. The receptacle is a 30 amp twist-lock.

>There is another option.

>Two Honda EU2000i or EU3000is generators can be phase-locked to produce two 120 legs with a neutral.

These generators are similar to the Yamaha :

>However, the inverter section of the Honda genny’s is notoriously fragile, and repair approaches the cost of a new generator.
