the brightness is the default, i only changed the radius but er, how do you change the brightness
i can only seem to change the colour :scratch
The color has 4 values. Red, Green, Blue, Alpha where alpha is the brightness. a yellow light for example should give somethign like: '220 210 130 800'.
Also note that default values arent allways the best and that too many lights might make them cancel each others effect out due to too many lights. Especialy with diffirent types of light the error can show up. And when it does if im right it goes fullbright. It however should mention that in the compile. (if you dont see it in the compile then it didnt happen)
and is there a clever way to sort of bind the model (in this case the flourescent tubes) into a light_ entity so i shines from it , i just placed the entity inside?
No, these effects change depending on the angle (particles) or objects blocking it (sprites). If you place a sprite inside a light bulb it never shows up. Just place it 4 units below the light and no one will even notice you did (unless its a mapper or someone with knowledge of mapping).
