I am looking to run a carbon arc lamp with a Nevelin mercury rectifier. I need a control box - the one which has STRIKE - BURN IN - RUN controls - usually found beneath the arc lamp. I need the one comtaining resistors for burning in, not just a remote control unit which simply switches in resitors back at the rectifier. The one in the picture gives an idea, although this one is just a remote unit with no resistors.

Sorry, way over my knowledge. Hope someone can help
