Wait a minute! Were that postulate true, I could take a bulb and connect it to a variac, and as I reduced voltage from 120, the brilliance would be constant, and as I neared zero, the bulb would fail, since you're claiming that at 10 volts supply, the bulb would draw 10 Amps?! Furthermore, if your point was accurate, then how would one explain the use of a simple rotary dimmer? They are rheostats, or variable resistors, and they reduce supply voltage to the fixture. :highly skeptical smiley:
