Limiting the distance a light illuminates objects

Is there any way I can make a spotlight stop illuminating objects from a certain distance onwards i.e. give it a cut off point ? I don’t want to make it cast shadows, just not cast light past a certain distance. I’m using several objects at different distances and I want them all to have the same illumination - I’ve got it just right for one of them, unfortunately the lighting effect seems to accumulate and make the further objects much brighter (even though distance is set low and the objects are widely seperated).

Tried ‘Sphere’ mode? This will constrain the light to within the ‘Dist’ setting.

Thanks, that’s just what I needed !
