Divide the wattage by the voltage. If it is 120Volt then the answer is .15Amp
...18 watts...
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
Use 100 watts
Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps. Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.
It's the 40W tube! because it's nonlinear: indeed it generates harmonics which increase the apparent power and thus the apparent energy.
There is no direct conversion for this, because these are two separate things. Watts is actual power usage. "Lumens" is how much light is provided from a specified amount of power. The typical light bulb converts some of the electricity driven through it into light, and the rest into heat. The more efficient the light bulb, the less power per lumen will be required.That is why newer bulbs can be purchased that are 13 watts and advertised as equivalent to 60 watt incandescent bulbs - the light output is roughly equivalent (lumens), but the power usage is substantially different.

A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.

Your question is rather like asking "How many miles per hour do you do in a week?" You don't consume watts over time, it's a measure of how many joules of energy you consume over time.

Convert the 100 watts to kilowatts. Calculate the total time in hours, and multiply by the number of kilowatts that the light bulb uses.
light bulb, microwave, telephone, tv, florescent light bulb
the unit which are measured for power of lights are watts....
Use 100 watts
Very little, but it is noticeable, with a bright light in a small room. A light bulb puts out between 9 watts (energy-saving fluorescent light bulb) to approximately 100 watts (bright incandescent light bulb). Your average bar-heater, for comparison, puts out about between 1200-2400 watts.
