Stop light bounce?

[aaouviz]

I have a colorful light 'projecting' light onto a white floor from a LightMaterial (applied to a simple plane) with a 'inclusion' turned on to project only onto the floor

It works well, expect the light is bouncing up off the floor and illuminating objects around it. Not desirable in this particular situation.

I've never come across this hurdle before, so not sure how I can eliminate the light 'bouncing'?

Is it perhaps some sort of combination of ray-switch and inclusion?

Any tips? Thanks!

you can use rayswitch material to override the GI.
