The more expensive Perma-Power brighteners were designed to be both isolation and boost, series or parallel. IIRC, it had four different configurations. It was twice as long as the cheaper units and had a five pin selector plug, to select boost or no boost, series or parallel. All the instructions were on the unit, to suit the application.
I might have one somewhere in my stash.
