Im interested in Low Flicker Index. I think that is a calculation that combines Pulse speed with Modulation depth.
note for example that the D2 and the Skilhunt have flicker index of 0.0017 and 0.0014
while the FWAA has a Flicker index of 0.0310
and the TS10 is 0.5005
as a rule of thumb, Flicker Index of 0.0500 or less is desireable to prevent migraines from long exposure to Flickering light sources. Even when we do not consciously notice the flicker.
Im not just judging by whether I can see the flicker with my eyes
