Problem with luminosity-texture

hello community,
I've already searched in the forums and found a lot of interesting stuff there, but no solution for my problem. Let me explain it:
I have a room, let's say it is a Shop with shelves and so on. At the ceiling I want to have a lot of simple spots. I didn't want to model all these little spots, because I need the model for a game engine, so I have to keep the polycount very small. So instead of modeling hundreds of circles, I just opened PS and made a texture for luminosity where all dots represent a light. With LW-Render it works well, but Kray doesn't show, nor does it use these luminous texture.
I will attach some image for better understanding.

Can someone help? Is this a general problem of Kray or am I doing something wrong?

Thanks in advance!
Daniel

no, I used LZMA for compression. maybe it's incompatible with your zipper.
I updated the file above, please try again.

I setup for You this scene.
Was, I think bad setup UV map for lumi.
Inside files You have full setup for High Quality with new features and Tonemaping.
Please don`t use specular and 100% diffuse (this is not real)
Please don`t use small luminosity surfaces. In scene I was setup it only for visible.
Better is use Area lights or Invisible lumi poly.
Don`t use very high lumi surfaces (500%) is opimal.
