Lightbaking and 'Brighter' than diffuse textures

[shivanangel]

Alright, stupid me posting right after!
I noticed the x1, x2, and x 4 buttons and they seem to do something 'similar' to what I want and blow out the texture values.

However, I can't seem to blow out the values when left at 1x.

Any chance you could describe what this is doing behind the scenes?

I'm experimenting with the internal gamma and exposure settings to try snd get this right.
