We power the contactors off more often now if lights are generally 24/7, if contactor fails, fails closed and no loss of lights or em supply

Since the emergencies are fed from separate contactors doesnt that undermine their function? If the lighting contractor fails but the emergency contactor doesn’t wouldnt that leave the area without light? Unless its a maintained system that is
