What happends if LVQ-212 are powered without bulb connected?
The ballast cannot sense if there is a blub at the end of the wire or not before 23KV is applied. The nature of high voltage is to find the shortest way across and create an arc there. In a P32-d application, the arc will strike between the center and the outer terminals. The first strike will discolor the red plug inside. Many additional strikes will make deep grooves in the plug. Continous resets might shut down ballast permanently.
