Check out your shaders' "INCANDESENCE" channel
Also, check F1 for specific usage, and pros and cons.
For example, one con is that it only "fakes" illumination, it doesn't actually "emit" light onto anything else.
TIP: If you remap your incandesence map to your shaders' glow effect, you can get a teeny bit more controll over your fake illumination
