The GM Station light, on high. It is backed with a sheet of mica, which gives it a very pleasing amber glow. The deck prism actually has a greenish cast, and was a bit too bright as is.

At one point, we were considering putting 2 of these prisms on 6 ft posts, that would overlook the table top... however, that was a challenge as I couldn't find anymore deck prisms to buy... and technically, the posts would have blocked eye contact between the GM and player, which isn't good at all.
