Flicker factor is used to characterise the potential for temporal modulation artefacts of a light installation. The flicker factor considers the instantaneous maximum and minimum values of illuminance at a point and is only relevant for television broadcast. Using LED systems would eradicate the need to consider this aspect. With LED systems, there may be other limitations to the television broadcast performance, and these will be related to the dimming technology used and on the LED refresh and camera sensor readout. This is a specialist broadcast-related element that will need further study if required.
