They may very well do a much better job with color consistency but I would rather read an independent review than see the manufacturer's claims. I know you're not very enthusiastic about the Alienbees inconsistent color used at less than 1/8 power (I've read the other threads) but a quick search on the consistency of the Photogenic light did not turn up any real review.
I did find this comment from someone who uses them:
"A couple of caveats: The flash time is long - as much as 1/125 second, so you have to be careful of the sync speed. Secondly, they have a rather long recycle time - about 6 seconds with a Turbo battery. Finally, there is little or no power regulation and the color temperature changes as you reduce the power level (this is typical except in very high-end flash units)." That came from here: http://photo.net …a-fetch-msg?msg_id=00H0sp
Again, I'm not saying the Photogenic StudioMax III are not color-consistent throughout their power range nor am I saying they're not good lights, I'm just saying I haven't seen anything that verified they're consistency.
As was mentioned in another thread, color consistency when reducing the power output of a strobe has never been a strong point of any of the lower-priced studio strobes. Everything I've read indicates you have to buy a high end strobe for that kind of consistency. In addition, the color temperature a strobe will change as it ages.
