This is a crop of my render test with cycles.
My Workstation: Win10, GPU Compute with NVIDIA 1050Ti How can remove all the light pixels in the scene?
Render settings
You need to set you Samples (of the render option) up very high (minimum of 300) to get of "Fireflies" (the name given to these pixels). Note: This will increase render times quite a bit.
Increase the Clamp Indirect value. Try start with 1. You can find it under Sampling > Settings.
