Don't let the color temperature changes in Action Mode scare you. The same happens with speedlights and $10,000 Euro packs with IGBTs. Remember, natural light varies from around 5000K to 10,000°K and there is no display of what it is. So when you need to really stop action, use Action Mode and either set your camera for the displayed color temp or shot RAW and adjust it.
Also, if you look at the color on the arms and water in baclionur's shots you can see the constant color and lack of shift between power levels.
Thanks for the tests baclionur. Rob Galbraith will probably post spinning wheel tests which are much easier to do far more definitive. I have done spinning wheel tests myself but don't like to challenge forum rules by posting them. I'll get some on our website pretty soon - I have more projects each day and little time.
The only "euro" pack I know in that price range is the Broncolor Scoro, but unlike what you mention, it does control the color temp and flash duration at once. And it does much more too (including delivering 3200ws - but there is a lower ws much cheaper too unless $2k is nothing to you).
They use what they call ECTC technology (Enhanced Colour Temperature Control).
"Flash duration and energy automatically regulated for optimum colour temperature" - from the manufacturer on the product's PDF available on their site.
You can also overwrite the color temp control manually and adjust for your old boxes that shifted or mix with other brands that are not color accurate, etc.
Under around 1200ws, the pack start letting you manually overwrite the flash duration. The lower you go, the more control and you don't have to go all the way down to lowest power to get full max flash duration under your fingers. On the Einstein, as you go down or up, the flash duration changes. You can't overwrite it and you can't control the color temp. Finally, the light can't attempt to do it for you automatically because it's not build that way. Color and flash duration are two different fonctions that share the same power suppy but work in parallel. Kind of like two lights in one instead of a one does it all.
Say you dump a bag of feeds in a bucket for motion stopping. All you do with the expensive equipment is push buttons to get the duration you want with the aperture you have decided on to get the effect you need. With the Einstein you need to move the lights to get the duration and stop you want and it's the light that controls the photo not the photographer 100%. Yet, for grains, gravel, etc., you may want to keep a little motion, but how much is what you control with the flash duration and more control at finger reach makes it even simpler. That much control and the fact that the higher price product would still deliver color accuracy and allow overwrite, makes them technically hard to compare no matter the price.
Since this is a forum, I would have liked more details on the brands and models you are referring to. "10K Euro" for such a statement is pretty vague and make it sound intentional, plus the statement is not accurate.
As for the price 10K is for a 3200ws, but a 1600ws can be purchased for $8k with a free high end head. Using logic, I would think between 3200ws and 1600w the last would be the closest you could compare a 600ws head to. I only mention this to correct yet an other inacurate statement. Again, you need to check things first or you make your statements sound intentionally off. If $10k is a lot to you I would imagine $2K is as well...
I bfigure if you came up with a comparable 1600ws mono that offers all the options build in the packs you are comparing to that would probably be a $2500 - $4500 Einstein mono head. Do it and we'll see for sure...
I believe the t.1 time for 3200WS Scoro at full power is 1/85 second and cannot be made faster without reducing power. (Can be made marginally faster using multiple heads). Hey, Zeus can do 1/300 from a single standard head at 2500WS
Yes, you can dial in a flash duration OR a WS value, but I guarantee you you can't dial in 3200WS AND 1/8000 t.1. If you dial in 1/8000 t.1 you are going to get a vastly reduced WS. Try dialing in 3200WS and 1/8,000 t.1 and you'll be in for a big surprise - it's physically impossible.
"ETC" is just a name for essentially the same thing Einstein does. There is no free lunch and one is free to interpret marketing info anyway they want, but I think you are interpreting it incorrectly . . . IE Voodoo magic.
See Scoro specs here:
http://www.bhphotovideo.com/c/product/599750-REG/Broncolor_10_2995_Scoro_A4S_3200_W_S.html#specifications ($11,000+) ($8000 - $10,000 . . . whats the difference?)
"ECTC technology (Enhanced Colour Temperature Control), aimed at preventing color shift over the entire output range" . . . . essential the same thing as Einstein Constant Color Mode . . . same XXXX, different name.
