As discussed in Color: Part 1, there are a number of useful measurements to consider when looking at a fixtures color. Below, we detail how to read two of the graphic measurements. 

Also included within the results are each light's Mired number and G/M index number. These numbers give context to the Correction Gels needed to adjust any CCT or G/M shifts from the desired measurements. Refer to the table below for different manufacturer's thresholds on each gel.

Each reading was done with in-house lights which see standard rental house usage. In each test, the newest available fixtures were tested to present as close to an ideal reading as possible. Readings were taken at full intensity with a Sekonic C-800-U at 1 foot from the source in a blacked-out studio. Despite these considerations, it is important to remember that every light will be slightly different and so it is important to run tests on your own when possible.

For additional context, please read Part 1 if you have not already done so.

Reading TM-30 Vector Graphs

Areas pulled toward the inside of the reference circle represent deficiencies in accurate color rendering that causes desaturation along the corresponding hues.

Areas pulled toward the inside of the reference circle represent deficiencies in accurate color rendering that causes desaturation along the corresponding hues.

The closer the red circle (the test source) lands along the black circle (reference source), the more accurately the source will render colors in the human vision system

Reading SPDs

Deficient areas may be offset by increases in other wavelengths

While large drops in wavelength densities could indicate poor rendering abilities with these wavelengths, if the spectral response of the camera does not see these areas well, it will not make much impact.
