Lights are extremely dark

[Mudbill]

You can connect a light to it if I remember correctly. Perhaps it's in the Entity tab of it. "ConnectedLight" that is. If not, you can always use the CallbackFunc to trigger a FadeLightTo to enable it via script.

But if you want it to be light all the time, you might as well just add the lights to your level. PointLight and SpotLight are good. BoxLight if you want a general brightness throughout the entire area.

If you use a BoxLight, set all the values to 0.1 or lower.
