How much distance is needed to not display the light blow out seen in the Enscape viewer?

I think that it's due to you using an IES light - the IES profile has light coming back beyond 180º - if you change to an Enscape spotlight it will probably do what you want, but it won't be as diffused a light. The other option is to change the IES profile you are using.

Exactly what Gadget said. You can understand the specific IES profile by putting the light close to a wall.
Or you can use one of the many IES preview tools, such as this freeware IESViewer.

I don't have this issue in other render engines such as Vray with IES maps.
See image below to a sample of maps that I use. None of these ies maps extend over 180 degrees, -
34 and 36 do: are you using one of them?

This is odd, I tired to reproduce your problem by placing an IES light in the center of the room and on the wall for reference:
I don't see the issue with the (almost done) 2.6.
Is the light panel / fixture emissive? How does the scene look like in draft mode? Can you send me the IES file and a small reproduction file where the issue appears and I can have a look.
