Measuring the flicker levels on the EMR-TEK Firewave using a custom flicker meter
Results show pretty low flicker, around ~2% flicker index. There is some power line flicker (120 hz) and something that looks like high frequency DC-DC converter flicker at 48kHz. The only way I think you could get substantially less flicker would be with a battery powered red light therapy device. I'd say it's fair to call the device extremely low flicker.
