Well these leds usually are towards the blue (around 4500-5000K)
For this aprticular see:
there other issues though...variations in performance bring another issue
Color categorization or binning.
There can be all colors EXCEPT yellow and variations of white like cool WC or warm WG white. To complicate matters further "cool white" etc characterize a whole region that touches the purplish white.Now this graph shows the range:
Then there is the "bin" the manufacturer buys and variation within that "bin". Us flashlight-alcaholics have already established the term "bin lottery"
THen there is the Color Rendering Index issue.....That only know are LEDs stealing teh incandescents' ground.(on this this new flash led seems remarkable at above 90 of a CRI)
THese may seem to theoritical for most of you, but the final message is that when the new generation of flashes come into the stores there will be all kinds of variance even within manufacturer, and a whole new craze of this flash is test better tah this etc.
Stay on hold, kostas

I wonder what the frequency or color of the light would be from such a device.
