I packed in:
Vector BFL 192 (2 - 100w)
Barn Burner (80W)
Homemade Mod (100w)
Battery Junction - L35
I was short a homemade 100W due to a ballast problem, but I packed enough light for the big rooms.

Dude...That is old school!
If you run out of light in a cave, you're usually toast until someone comes in to find you. There's no way you could make it out without a light.
I did run into someone caving once using a coleman lantern. They took out the glass and put in a tin foil reflector. They were pretty deep in the cave. I wouldn;t be too comfortable with that type of technology underground
