We should have non platinum members be nominated every week as the most helpful or something.  CHEERS ALL YOU GUYS.
 
Re: Rigging Ikegami TM9-1 Field Monitor

Something I found on the web:

---------------------------------

Portable watts:
Up in Canada the national home/auto/tool store (Canadian Tire) has started selling the "Motomaster Eliminator 1,200A PowerBox". Best as I can tell, it's just a heavy duty battery/charger/inverter combo strapped to a hand cart so you can actually move it. The specs are listed on the page but to sum up, 120V/12V power options (Canada uses 120V mains), 1200W capacity (no mention of surge capacity) and a 60Ah sealed battery.

Is it worth it? It lists for $CA250 (if memory serves, the Aussie buck and the Canadian tend to pace each other pretty closely). Certainly one can buy a battery, inverter, and charger for less, but can one save any significant money this way, and/or get significantly better kit for the same price?
Thanks

Answer:
The specs on the Canadian Tire site are incomplete, and I can't find this gadget better described anywhere else. No inverter has a wattage rating; presumably this is actually a 1200 volt-amp (VA) unit. If that's its continuous rating, then it could run 840 watts of power factor 0.7 loads (like PCs), or 1200 watts of power factor 1.0 loads (like incandescent lights), et cetera (I explain this in more detail here).

But the quoted number might be a surge rating; at that price, I wouldn't be surprised. A 1000VA (continuous) modified square wave inverter that costs only $CA300 (which, as you say, is about the same as $AU300) is a pretty big bargain. This is supposed to do 1200 something-or-others, and includes battery and charger and cart as well. So something don't add up, here; it's too much of a bargain.

Just in case you were looking to buy it... :-/

The bottom line is that with a single 1K light, you are going to be sucking juice out of the battery in a hurry. A deep-cycle battery is typically a marine battery that is made to have a buncha juice sucked out in a hurry. If you are planning on more than a single 1k (what about key and filler?) you might just want to look at generators.

I too looked at an inverter solution, but decided to go the generator route with big thick cables so I could put the genny a long way away.
 
Re: Rigging Ikegami TM9-1 Field Monitor

When power is an issue, that's when fluorescents become more attractive. Fluorescents deliver about 4x as much light, per watt of electricity used, as tungsten does. However, fluorescent is inherently soft and it's very difficult to get them to emulate a hard light. But if soft light is okay for what you're doing, you could power over three dozen 27-watt compact fluorescent lamps for the same power draw as that one 1K light.

That's true... I've been a big proponent of Kinoflos for video use. It's beautiful. But for film it's ugly and I forgot about that....

Also, getting long long thick cable and keeping the generator is a good idea to solve the generator souund issue.
 
Re: Rigging Ikegami TM9-1 Field Monitor

You'll need a very, very, very long cable, cause, even using the onboard mic, let alone a good aftermarket, it's going to pick up a generator running, unless of coarse you're shooting in the middle of town.
 
Re: Rigging Ikegami TM9-1 Field Monitor

see I knew it. damnit... what should i do....... maybe get one inverter per light.... i'd be so broke. maybe i can wrap the generator in a sound blanket and then put that in a sound proof case i can order from nasa or something. but i'm assuming the generator would need oxygen among other things.
 
Re: Rigging Ikegami TM9-1 Field Monitor

Where are you planning to shoot?

Type of location, inside, outside etc.
 
Re: Rigging Ikegami TM9-1 Field Monitor

Figures...couldn't be downtown at noon....

Let me think, whats the timeframe?
 
Re: Rigging Ikegami TM9-1 Field Monitor

Time frame? Well, the scene takes place in one night.
I have shooting scheduled there for one night with a saftey date of one night...
It's two pages of a script, so it's about a minute and half - two minute scene. The second portion of it will be composited with greenscreen effects so lighting has to be very very specific. I have a lightingg diagram with distance and wattage marked so i can recreate it in the green screen studio i've rented for 3 hours.
 
Re: Rigging Ikegami TM9-1 Field Monitor

For a generator solution, I bought a small Honda 1200W and made a simple lean-to rig to drape moving blankets over the exhaust side of the genny without getting near the exhaust pipe. The putt-putt sound is deadened and if I can put the genny near the mid-axis of the mike, I don't capture it at all.
