ABSOLUTE SERIES™ LED Linear Modules Flicker Rate


I was looking at the photometric reports on the ABSOLUTE SERIES™ LED Linear Modules and I had a few questions. 

The 6500k reports a flicker rate of 3Hz and the 5000k reports 115Hz. Is the 3Hz accurate? In looking at the flicker index I see it reported as 0.00. In my understanding the index is calculated as the area above the mean divided by the total area, I do not see how this could be 0, is the number accurate, or is my understanding of the calculation off? 

Though the flicker rate is indeed noted within the photometric reports, please note that the flicker-free feature is the result of the connected power supply rather than a result of the product’s bespoke performance. 

​In this instance, the module was connected to one of our TRIAC Dimmable Power Supply for LED Strip products. This flicker rate would change if the module was connected to a different power supply that was not flicker-free.

We can confirm that the flicker index is on a scale from 0-1.0, and is measured by the area above mean divided by total area. Further, the flicker index is a measure of the cyclic variation accounting for the waveform shape. As there is no altitude variation between the maximum value and the minimum value within the frame of one optical cycle, the flicker index of this product is 0.00.

By my reading, the Hz denotes that during 3 Hz (or 115 Hz) of refresh time, a minuscule change occurred that was negligible enough to not cause any adjustment to the overall flicker percentage or flicker index.
