Had same problin. Cured by adding a 5 amp diode in seris with the hot side
of line voltage. Installed a 300 watt bulb. Diode dropped wattageto about
75 watts. That was 24 years ago, WW
A 300 watt incandescent with a diode dims to brightness of about a 75 or
100 watt incandescent, but consumes about 175-180 watts. (Not 150 because
the cooler filament has lower resistance.)
Thank you. I will add that the same holds true for dimmer switches.
They waste a hell of a lot of electric due to running lights at less
than their rated wattage which makes them very inefficient.
Three way bulbs in table lamps save more $$ than any dimmer switch.
I wouldn't call a dimmer inefficient. If you mean it uses more than 1/2
the power to put out 1/2 the lumens, so what? You're still saving money
when you dim the lights. Almost every light in my house is on a dimmer,
including the closet. It's all about the mood.
