Best portal 2 testchamber lighting?
Hey forum.
For a few days now I've been making a nice Map. When I tried to get the Gels to work, they were invisible. After reading somewhere that there had to be map-lighting, I made a light-entity and it worked. But now the light doesnt seem to want to do what I want it to do.
When I make the light, it is clearely in the room and there are alot of dark spots and shadows, even though i made a bright one, unlike in the basic testchambers.
I could try spamming light-entities in the testchamber but i'm quite sure there is another way. 
Could someone tell me how to make a nice and normal lighting without shadows and such, as seen in the valve testchambers?
It would be a great help! 
Using only light entities isn't enough.
I use the glass lights in my test chambers.
Here's a link to the VDC page which explains what that lightning is, and how to make it.

And here's a YT tutorial on general lighting in Portal 2.
