Something bothers me about color temperature vs. power setting testing. When you conduct these tests, one must be aware of the conditions that the test is performed. So for instance, as you decrease the power, you are openning up the f stop to keep up with the power reduction. If there are other light sources around, they may be interfering with the result at lower f stops.
One would expect that xenon gas should be consistant when a current runs through it. There are a few ways to reduce the power. Keeping the voltage on the capacitors constant and removing capacitors, is one way. Or, keeping all the capacitors available for discharge and variing the voltage would be another way. Another method would be to keep all voltage and capacitors in play and shut off the discharge when the appropriate power was discharged. The questions is, which meithod would yield the best consistancy. Also, does the flash tube temperature change the results. That is to say, if you start out high and dial down, do you get the same result as if you started cold at the lowest setting and worked your way up?
The best way to test them is under the real-world conditions that you typically use the lights. If you test them under rigid conditions in which you don't normally shoot, then any abnormalities are irrelevant. If I typically use a lens in studio within the f8-11 range and it gets the job done to my satisfaction, then any issues I might see at f2 matter not a bit. If you go looking for problems, you will most certainly find them.

. It really does match the case you can see in the background!
