The LFX Master DMX and LFXHub use high resolution flicker CURVES with sequential dimmed values.
All built-in effect engines of LED fixtures use random patterns of a variation of fixed values.
For that reason all "organic" effects like fire, candle, welding, lightning and TV take advantage of the pre-programmed flicker curves with 24 fps resolution which ensures a natural look.
Even the LFX Master dim uses the same quality of flicker curves as used in the LFXHub and LFX Master DMX.
