If you want to upload the project I can take a look. The lights should not get brighter farther away (however if you don’t have inverse square chosen in fall off they will be the same brightness far away which might make them seem brighter because the world doesn’t work that way).
Also don’t be afraid to double up lights. You duplicate lights and leave them in the same spot but assign them to other objects or make them dimmer or turn off shadows so that you can tweak the effect you want to get. Its a great way to soften shadows when the blocking object just has too much of the dark side in it. Simply turn off the shadow for the lights twin and that light will pass right through the shadow blocker object. Then just adjust each of those light’s intensities so they add up to what you want.
