A lumen is the perceived intensity of the light, as seen by the human eye. The lumen value is largely determined by the the nature of the light, i.e. the sum of the different wavelengths of the light being transmitted by the particular bulb type.
The standard tungsten wire-filament ('incandescent') bulb radiates a different type of light to a flourescentlight.
* a 230 V, 40 watt incandescent bulb produces a light (quality) of about 400-500 lumens,
* a standard 230 V flourescent lamp of only 7 watts will produce exactly the same value of lumens, i.e. 400-500 lumens. * the cool white XLamp XP-G 3.5 V LED lamp of only 3 watts will produce a similar value of lumens, i.e. 350 lumens. And is safer for the workers that make them and better for the environment. It is currently more expensive, but prices have been dropping about 20% per year. Therefore LED light bulbs convert electricity into light more efficiently than incandescent or florescent light bulbs. * For more information, See Related links below this box
If we assume a standard household voltage of 120V, the amperage of a 40-watt light bulb can be calculated using the formula P (power) = V (voltage) x I (current). Therefore, for a 40-watt light bulb at 120V, the amperage would be approximately 0.33 amps.
I think the term you mean is "candle power" (candelas is a conversion of the power of a bulb in comparison to the power of a candle) The standard 40 watt bulb power would depend on the configuration of the bulb. (the filiment array, shape of the bulb, amount of refectors or "prizims" incorporated into the face of the bulb as in a flood light) The standard 40 watt bulb in your desk lamp average 25 to 29 candle power. A flood light would generate roughly 35-40 candle power, again, depending on the size of its face.
A 100 W incandescent bulb produces about 1750 lumens or 137 foot-candles
A 23 watt fluorescent light produces about 1600 lumens or 125 foot-candles
A lumen is the total amount of light visible light emitted by a source. A 100 Watt CFL will emit 1750 lumen.
The formula you are looking for is I = W/E. To answer the question the voltage applied to the light bulb must be known.

How many amps does a 65 watt light bulb have at 120 volts?
To calculate the amperage, you can use the formula: Amps = Watts/Volts. For a 65-watt light bulb at 120 volts, the amperage would be 0.54 amps.
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 does 65 watt light bulb draw?
A 65-watt light bulb operating at 120 volts draws approximately 0.54 amps of current. You can calculate this by dividing the wattage (65 watts) by the voltage (120 volts) to get the amperage.
How many amps does a 65 watt light bulb use?
A 65-watt light bulb typically draws around 0.54 amps of current when operated at the standard voltage of 120 volts. This can vary slightly depending on the exact voltage and type of 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 amps does a 65 watt light bulb have at 120 volts?
To calculate the amperage, you can use the formula: Amps = Watts/Volts. For a 65-watt light bulb at 120 volts, the amperage would be 0.54 amps.
How many amps to light a 60 watt light bulb?
A 60 watt light bulb typically draws 0.5 amps from a 120-volt power source. This is calculated by dividing the wattage (60 watts) by the voltage (120 volts).
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 does 65 watt light bulb draw?
A 65-watt light bulb operating at 120 volts draws approximately 0.54 amps of current. You can calculate this by dividing the wattage (65 watts) by the voltage (120 volts) to get the amperage.
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.
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.
What is the current in anACcircuirt with 12-v0lt And a 60 watt light bulb?
A 60 watt bulb at 12 volts will pull 5 amps of current.
How many amps does a 65 watt light bulb use?
A 65-watt light bulb typically draws around 0.54 amps of current when operated at the standard voltage of 120 volts. This can vary slightly depending on the exact voltage and type of 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 amps does a 120 volt AC 8 watt led bulb draw?
It is drawing .06 amps.
How many amps will a 60 watt bulb draw from 120 volts?
Watts = Volts x Amps x Power Factor. An incandescent light bulb is a resistive load so PF = 1. ANSWER: = 1/2 Amp
Who created light bulb watts?
Thomas Edison invented the vacuum sealed filiment light bulb. James Watt coined the term "watt" as the work done by an electrical circuit, which can be calculated as Volts multiplied by Amps.
