What is your opinion about probably additional voltage drop due to load rising? According to figure below, in right hand of vertical red line which illustrate optimum source impedance ( resistance of interconnection cables equal to load impedance) the increasing of lamp number ( electrical loads) cause electrical output reduction or lamps illuminations.
