This projector can be operated using low and safe voltages. In addition, heat generation is extremely low in this projectorand noting that no relays or short junctions had been considered in design of the projector, the risk of electric shock, burning, fire have generally decreased dramatically and removedand many of safety points that must be met in the old projectors, do not exist here.
Used voltage in PMPLE is very low and it is interesting that PMPLE projectors will illuminate with a small amount of their rated voltage and it can be fed with the weakest and the smallest batteries. Therefore,it can be fed without any needs to connect to the overall network, and just by connection to direct batteries and cells and even clean energy which somehow has removed the peak and valley problems of the network load. Also the construction cost of electric power plants in impassable places and far-distances has been reduced.
