Lights are extremely dark

[FlawlessHappiness]

You can connect a light to it if I remember correctly. Perhaps it's in the Entity tab of it. "ConnectedLight" that is.

This is true.

On any lamp entity, there is a box called something like ConnectedLight. All you have to do is type in the name of the pointlight that has to light up, and pick the color of it. The actual point light should just be black.
