So I went and bought 100 frosted LED's. My opinion on them is they look great strategically placed. I filled the back box in Dracula with them accept for a few locations behind a sunset scene, a torch and the moon. General lighting above the playfield is where I'm experimenting. I put them under inserts so far and they really look nice, but above the playfiled it's really hard to beat that tungsten glow. I've seen a mod with a lot of blue LED's, and although it seems to look good I'm worried about the "strobe effect." There's a little bit of ghosting going on but I never notice it during gameplay, so I don't have a problem with it.
