  1. From my own experiments, I tend to believe that brown outs (as opposed to black outs) have the potential to start house fires. Here’s how… You know those curly “twist cone” light bulbs? From my own electrical experiments, they present a potential fire hazard WHEN you steadily supply them WITH ONLY 50Vac (instead of the standardized 115Vac.) When only 50Vac is supplied, the mercury vapor fails to significantly conduct electricity. INSTEAD, right at one (of the two) points where glass tubing exits the plastic base of the bulb, the PHOSPHOR DUST COATING will conduct electricity. When this happens, the phosphor dust coating ACTS LIKE A RESISTOR, while continuously… • throwing A LOT of Heat; and • producing a small zone of Orange Light. If the application of 50Vac (i.e. a brown out) goes on long enough, the plastic base (of the curly “twist cone” light bulb) will melt, followed by dripping AND catching on fire. You don’t have to take my word for it. In a controlled environment, on a Test Bench, you can combine a suitable Variac with a typical curly “twist cone” light bulb, and thereby sustainedly supply only 50Vac to the light bulb (which duplicates the conditions of a typical brown out.)
