Director of Photography Timur Civan used the C-700 in the 2017 LED Light Shoot Out where 28 of the industry’s leading LED light fixtures were tested for color accuracy in daylight and tungston modes.  This was a very thorough test and quite useful.

28 LED light color accuracy shoot out

I have and use the C-700 spectromaster and have been testing the LED lights available for standard lamp sockets primarily and its a very useful tool.  What I find the most useful is to see the CRI histograms to know which color segments are missing from a spectrum.
