There is no question that LED is now leading the lighting industry. This is great news but we need to be careful how we proceed.  Unlike tungsten, fluorescent, or hmi lighting, there hasn't really been a standard set for LED lights.  That has to do with difference in manufacturing and the speed at which companies are flooding the market with their lights. 


We went to NAB to test for ourselves using the Sekonic SpectroMaster C-700-U.  For the purposes of our test, we measured the CRI value or Ra which is an index, a measure, that tells something about how colors are represented by light coming from a certain light bulb, compared to how the colors are rendered with the light coming from a reference illuminant.

The CRI reports a unit less value, that can differ between 0 and 100. The value 100 means that there is no difference in color rendition between the light of the observed light bulb and the light of the reference illuminant.

In other words, the closer to 100 the better. 

Many LED fixtures have a hard time with the R9 and R12 vales, saturated red and saturated blue respectively.


The CRI (Color Rendering Index) displays General CRI (R1-R8), Rendering Index Average (Ra, average of R1-R8) as well as Special CRI (R9 to R15) to show how accurately different colors will be reproduced.
