The ones I bought to investigate using as SLA battery chargers actually put out bursts of 17V square waves with a burst duty cycle (at mains frequency) around 70%, giving the same heating effect as 12 V which is all the lamp cares about. Completely useless as battery chargers, might casue problems as V/T heater supplies too.Mark Kelly
