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.
What else can I help you with?
How many amps does a two-bulb 32 watt 48-inch fluorescent light draw?
Each 32-watt bulb in a 48-inch fluorescent light typically draws around 0.27 amps. Therefore, a two-bulb setup would draw approximately 0.54 amps in total.
What does f17 stand for on fluorescent bulb packageing?
F17 on a fluorescent bulb packaging typically indicates the type of bulb and its wattage. In this case, "F17" refers to a T8 fluorescent bulb that operates at 17 watts.
How many lumens in a 32 watt fluorescent?
A 32 watt fluorescent bulb typically produces around 2400-2900 lumens of light output. The exact lumen output can vary depending on the specific type and brand of the fluorescent bulb.
How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
Which type of ligh bulb uses phosphors?
A fluorescent bulb
How many amps does a two-bulb 32 watt 48-inch fluorescent light draw?
Each 32-watt bulb in a 48-inch fluorescent light typically draws around 0.27 amps. Therefore, a two-bulb setup would draw approximately 0.54 amps in total.
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.
What does f17 stand for on fluorescent bulb packageing?
F17 on a fluorescent bulb packaging typically indicates the type of bulb and its wattage. In this case, "F17" refers to a T8 fluorescent bulb that operates at 17 watts.
How many lumens in a 32 watt fluorescent?
A 32 watt fluorescent bulb typically produces around 2400-2900 lumens of light output. The exact lumen output can vary depending on the specific type and brand of the fluorescent bulb.
Who invented fluorescent light bulb?
EEdmund Germer (90% sure) made the first fluorescent light bulb
How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
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.
Which type of ligh bulb uses phosphors?
A fluorescent bulb
How many amps does a 120 volt AC 8 watt led bulb draw?
It is drawing .06 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 many mercury atoms are in one fluorescent light bulb?
in a compact flourescent about 8mg.
