This is some amazing information! I'm so pleased that this has been clarified as all of the lights produce a bit of a muddy color...although not so much with the westcott flexes, but I have yet to examine the TIFF files.

Anyway, I'm not coming from a science perspective, I'm coming from a location video shooter - producer - director perspective...

Now, I guess my question for both Akos and Timur Would be this...is there a way to measure these photos with the Spectroradiometer to find out which of these LEDs is the least muddy?

I would prefer to use Tungsten lights, but I shoot so much on location and having a light with a battery is...well...da bomb.com

Tungstens may look better, but if you don't have a budget for a generator...and that whole story...well...I'm happy just to get a nice exposure on my subject as the sun sets behind them.
