Have you ever had to balance LED lights? If you have, you know it is a nightmare. For once not all 6500K are created equal and even if all the LEDs on your setup are set to 6500K, they light output is slightly different. The other thing is that regardless of the color temperature, LED lights (and other pulsing lights, such as fluorescents) do not show a consistent light pattern.
This inconsistent light pattern means that a graph showing the color signature of an LED light may have spikes on certain colors. (have you ever heard on the horrible green spike?). Here is the thing though, (in general) the color meters that we currently have are not built to measure those color spikes, they assume that the signature is linear and sample the light color at wide intervals. Those wide intervals may cause the light meter to miss a spike (or a valley).
This is where the Sekonic C700 comes into play. We had a chat with Sekonic International sales director, Lorenzo Gasperini and he explained to us how the C700 is coping with those issues. There are some good news. Apparently, Sekonic rushed production and only had 2 of the C700 units produced, and even those were not guaranteed to be the final models. And there is nothing more exciting than putting your hands on a one of a kind unit :). And yes, the screen was stellar
