Thanks @prisoner849 a lot for taking the time to answer!
Now about the main goal—it’s to achieve something similar to LED lighting under the bed or under a gaming table. The light shouldn’t just have an emissive glow; it should actually illuminate the space around and beneath it. For example, even in a completely dark room (like during the night cycle), the LED light should make the area under the furniture clearly visible.
I tried using a RectAreaLight, and while the result wasn’t bad—it does cast some nice soft light—I’m still looking for a solution that can feel a bit more intense and focused, like a real LED strip. I’m also interested in possibly adding RGB-style effects, like subtle color cycling or breathing animations.
If you have any ideas or tips on how to get even closer to that kind of effect.
