Remove Spotlight attenuation?

Hello,

I can’t figure out if yes or no I can keep the same light intensity all of it’s length.

I m setting up a night vision PP with a spotlight and I need to put the light intensity at 12000 to reach the length I want even the attenuation radius set a 16k.
The problem is that at 12k intensity when I m close to a mesh it’s way too bright.
I d like to set the intensity at 5k but keep it all of it length, is there a way?

I ve tried to work with the PP indirect lightning and gamma but I really want to keep dark this visual so I only want the spotlight light the scene.

And Thank You!

The answer was IES…

If anyone needs an outlast NV type, use those settings as a start its the closest a could do but much more than any tuto i found
