@Robosprog - Do you mean the "EffectColorMul" property?

For "ceiling_large", you can change the billboard color attached to it, with that property. I don't know if every lamp model is set up correctly like this, but it is possible to change it.

Doesn't work on every one, I've tried. On top of that, billboards show up when the lamp is unlit, which is even more frustrating.

I opened up that lamp in model editor. Turns out it's not because of the billboard being hard to change, it's because that lamp does not even have a billboard, the glow is coming from the material itself, and more specifically, it's illumination map.
EDIT:

Under appearance, changing the illum color will give you desired effect:
