I’m pretty sure that re-lamp draws less than 400 watts AC And the transformer is built-in. so it’s 110 V going in. It will work just like a Quasar and you can use any AC dimmer for it. I’ve used a harbor freight router control to dim them

If it will always be completely locked down, then any head that will hold a large format still camera should work fine. We used to use the majestic geared heads for big heavy cameras, but you’ll have to adapt it since they worked on 2 inch diameter post. You can occasionally find them with a 3/8 thread in the bottom If you need a cheap solution for an ok fluid head in that range Try the Manfrotto 510, 516, 526.

Cool Lux made a small zip light like that, I had thought about using for an obie. Been looking for the perfect instrument for a long time. I like the mechanical dimming on the Arri.

so it sounds like there is literally no solution for GFCI use when we just want to use a small HMI in the backyard, plugged into a 20a residential outlet?

thanks for the detailed info Guy. I looked at the manufacturers you cited, the only product I could find that is appropriate to what I'm doing would be the one by Lifeguard, https://www.guardiangfci.com/products/lg20-line. I use the Voltec https://www.voltec-industries.com/copy-of-04-00103 for extremely small projects involving a couple lights. I haven't had a problem with them tripping (yet). Typically I'll plug in a parcan or a couple litemats/panels. I appreciate your thorough explanations, but can you give a non-electrician comparison of these 2 devices, and a dealer for the LG20 if you know of one?

Phil, I use some inline 20 amp GFCI's that are commercially available (120v) made by Voltec

a tiny jib? or hang the camera with bungees from speedrail and have 2 grips carry most of the weight?

The first thing I would do is explain to the producers that they've made the job impossible. If you still want to do it, then it will have to be some unusual look, like edge lighting with quasar tubes, or find a location that has a big white wall you can light up for a clean reflection on the car.

did you do this shoot already? If not, how much time do you have and what G&E gear budgeted?

C stands are definitely the wrong tool for any of that, so that only leaves your combos. Of course I can't actually recommend doing it that way, you really need to make that determination on site. Is it interior or exterior? Consider using or building truss for the goalpost.

I wouldn't ever do a goalpost on C stands. I might do the goalpost on the Combos for the 300Ds and hang the 8x8 from the goalpost also. That will get the stands farther out from the car than 8'. also you won't get an even reflection out of quarter grid. Satsuki has some good ideas there too. long ago we made frames up to 5' x12' out of furring strips and skinned them with white nylon or polyester from the fabric store.

You may find a viewfinder app will be easier overall. It is useful for other reasons as well, like storyboarding. The optical viewfinder you can calibrate by eye to your windowd sensor and focal lengths as well

Yes that should work fine, you may need to adjust The indicated focal length, depending on your sensor size. If you need specifically 1.66, are you windowing a digital sensor, or shooting film?

I have the model iiiB, which has 1.66 aspect. They are fairly available on the used market if you need an older model for that aspect ratio I don’t have my Alan Gordon with me at the moment, but I’m pretty sure that also has 1.66

Viewfinder apps are really very very useful and you should have one either way. however, I really like using my Birns and Sawyer viewfinder, for the same reason I operate with my eye on a viewfinder. The Alan Gordon one is very nice, but I find it’s image is a little smaller. Keep in mind the optical viewfinders will not have a setting for micro 4/3 or any other newer sensor sizes

great find, thanks for posting that

I forgot I sent this on the truck just in case so I got a picture. I forgot I sent these on the truck just in case so I got a picture. These are not a pole op fixture, but I think they come that way also because they are studio sized IYou can see the bright wheels that the barn door ring rotates in I should check the Box book either way, but I don’t see anywhere that a standard size scrim can fit -13 inches definitely wider than the slots behind the “wheels”

I’m away on film right now, but can get some pics next week.

The barn doors are actually bigger because they ride in rotating bearings, different from every other fresnel I have ever seen

Thanks, i have lots of strand and quartzcolor lights to take standard scrims, but these are huge studio lights, so maybe that’s why. Of course they always list as metric sizes too

Thank you. I should have mentioned, I’m hoping to find a source in the US

anybody know of an easy-ish way to get wire scrims for Strand/Quartzcolor instruments? I need 325mm...

last time I looked the replacement lamps for those were very expensive. I have a couple source4 HID instruments that I used Coollights daylight lamps in. They worked very well. I don't know if they are still available. At this point I would recommend an Aputure 300D or equivalent though over that Arri

I've run a couple hundred watts using an inverter on a car jump start battery. Not elegant but it works and it's cheap. There are some "power packs" that are big batteries with inverter built in.

Thanks I may have to try the Zircons. I do some gaffing where I'm unfortunately stuck with daylight only LED. Anything better than the current situation will help.
