Working with Lights in Doom 3

[mrfiend]

Hello,
I have been using NetRadiant for a while now, but I just recently got into mapping for Doom3. I am having trouble with lights in Doom3; specifically, if I don't have a light entity in the map, then it will be pitch black. I can put in some brushes/curves/models with light shaders, but they only glow, no light emits from them. I tried to target the light to the brush/curve/model, but nothing happens. I've tried to find a function or something else that I could set a light to them, but I've not found anything.
Thanks in advance for your assistance.

i don`t know how doom 3 can be scary anymore if you make all things light....

My issue isn't with adding more light to the existing game, but instead, working with them for my own maps.
