how to do so light only affects one object and not others

[d7man2000]

I want to have a stronger light on one object without affecting the other objects but I don't know how to do it, there is exclude in light properties but for shadows only.

when you click on a light's "exclude" button inside the dialog box, there is a selection of excluding/including either illumination, shadow casting, or both.... you would just switch it to illumination. And of course if you just want one object, then switch it to "include" instead of "exclude" and select your object.
