“Transitions” adapts effects to the duration of persistence of various types of filaments or to LED lamps. See sample clip: fire effects
The timing difference between the moment of electrical deactivation and the time of a completely extinguished light depends on the power of the bulb.
Choose the transition mode depending on the connected type and size of lamp (bulb inertia).
Thus any lighting effect looks excellent – with a 10K, a redhead, a standard 60 W bulb, fluoros or LED.
