Get light values

In interior render, I'm trying to get the values of nearby universal lights. I'm using this for cg bumpmapping. I've run through the Synapse macro and I don't see anything I could use. Stock TGE contains 3 versions of getBestLight(), none of which are ever used, thus providing no examples. I'm also unable to determine if they would work with Synapse lights.
The values I would need are light direction and ambient color.
I realize this isn't a Synapse centric question, but I figure if anyone knows a simple answer, it would be the master of lighting :)
