"Firefly" effect, Physical light creates white pixels

[Mohamed Salah Bchir]

Hello, when I render in a relatively dark environment i get the effect of "fireflies", small whites pixels coming from the physical lights, how do i get rid of that?

to reproduce the problem you would need a darker scene and area lights
