There is an option on the Irr Map tab called “Check Samples Visibility”. This is used to use only those samples from the irradiance map, which are directly visible from the interpolated point. This is going to avoid the light leaking specially when you have a thin wall and different illumination on both sides of the wall. This option will also increase your render time.

Best

Hi
The setting are kind of medium low quality. Another option that deal with the light leaking is “Retrace threshold” on the LC, but right now it’s missing. We have plan to include the option on the next beta For now try to increase the HSph subdivs to 80. reduce the Color threshold to .25. If you still having the issue you could use Details Enhancement "Radius 60-40 and Subdiv Multiplier .3.
