Electronic circuitry for realistic operation of Viessmann fluorescent lighted lamps in all scales. Useable with LED lights, too. After switching on, the fluorescent tubes flicker for a prototypical time until they all reach full output and burn uniformly. Each lamp operates slightly differently. At one of the outputs a defect fluorescent lamp can be simulated. This tube will flicker in irregular intervals, sometimes lighting up quickly and other times very slowly. 5 separate outputs with different starting patterns. Each output can drive 3 lamps. We recommend connection of only one lamp to each output, since no 2 lamps will ever operate exactly the same way in reality. Switching on / off is effected via a separate momentary action switch, e. g. push-button panel item 5547.
