Light falloff doesn't work

Hi,

Im trying to dim the lights further away from the camera, by adding the Light Falloff node to the strength input of the emitter, but it doesn’t seem to do anything? Is there some other way to do this?

Custom falloff with that node can only be done through stringing the linear output through a serious of math nodes.

If done correctly, you can shorten the range of the lamp as much as needed.

But whats the point of adding Math nodes, you are just altering the strength value, right? So just set the value directly in the Light Falloff node. By default lamps seems to be Quadratic in nature so I can see adding the falloff node and connecting the Linear to the strength.
