What are the disadvantages of PWM (pulse width modulation) dimming?


Following are the advantages of PWM dimming:

Relatively more expensive

Flicker perceived in peripheral vision if the driver is run below 100Hz frequency

Stroboscopic effect evident in fast moving environments when the driver frequency is low.

Electromagnetic Interference (EMI) issues due to rise and fall of the current in PWM dimming.

Performance issues arise when the driver is mounted remotely from the light source.
