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.

How many amps does a two-bulb 32 watt 48-inch fluorescent light draw?
draw 0.104 amps
Dim fluorescent bulb?
No...
How many volts does a fluorescent light bulb need?
The correct voltage should be printed on the light bulb.
How do you work out how many amps a forty watt bulb uses?
figure out how many amps are in a watt and x by 40
Which type of ligh bulb uses phosphors?
A fluorescent bulb

How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
Amps used by 32 watt fluorescent light bulbs?
If it is a 120volt light, then it is watts / volts. 32 watts / 120 = .2667 amps. <<>> fluorescent lights usually have a power factor around 0.6 so a 32 watt bulb would take around 32/(120 x 0.6) amps or 0.44 amps.

Who invented fluorescent light bulb?
EEdmund Germer (90% sure) made the first fluorescent light bulb
Which type of ligh bulb uses phosphors?
A fluorescent bulb
How many amperes does a standard 60 watt light bulb use?
Watts = Volts X Amps. Amps=Watt / Volts. So, with a 240V mains, a 60W bulb draws 0.25amps. On a 12 system (car/auto) a 60W bulb draws 5 amps. On a 110V mains, a 60W bulb draws .55 Amps.
How many volts should I be reading at a fluorescent bulb?
The voltage present on the secondary side of the ballast (transformer) varies as to the type of fluorescent tube or bulb that is in the fixture. The voltage will always be higher that the applied line voltage that supplies the ballast.If the fluorescent bulb screws into a lamp type of fixture, then there is no way to measure the voltage at the bulb as the tube and ballast are a combined sealed unit.
How much is a fluorescent bulb?
fluorescent light bulbs are usually from 9$-15$.
Can you use a 65 watt fluorescent bulb in a metal halide light fixture?
No, the ballast's output is not matched to operate a fluorescent bulb.
