Iris (EYE made) 160w SBMV blacklight lamp

Came in a rather plain cardboard box, from an Ebay seller who I'm sure you will all know by now! The filament in this lamp is interesting, the effect it gives off is very neat, a nearby piece of paper turned blue (as expected!) A giveaway it was made in Japan by EYE is the blue glass insulator in the base. (Do any of the collectors with B22 versions have this as well?)
