Approximately 720 kilowatt hours for full time operation. Depending on the price you pay for electricity, that would be around $7 a month to operate full time.
To answer this question the voltage of the ballast must be stated and the type of lamp in the fixture.
Max amps would be 1000 divided by 120.
close to thirty times as much as she uses in a day to put a quantity to this we need to know if she wanders at night and uses an incandescent or led flashlight or perhaps a candle or kerosine lamp
20 Watts x 24 hours x (days in month) so 31 = 14880 wh 14880/1000 = 14.88kwh
When you buy the bulb. All of those specifications should be on the package. To figure the Kilowatts it's pulling and cost to run. kW = amps x volts / 1000. then just take your kW x price per kw. and that will give you how much it costs to run that bulb for one hour. The amperage is on the label of the ballast. When you connect the ballast to power you will see it along with the voltage and pf of the ballast. F40T12 twin 8 foot tubes, ballast usually draws about .75 amps.
Yes, if that is all that is on the circuit.
