First of all, lamps (or any other electrical appliance, come to that) don't 'use' power.
'Power' simply tells you the rate at which your lamp consumes energy. A 60- W lamp is using energy at the rate of 60 joules per second -i.e. for every second the lamp is on, it is consuming 60 joules of energy. This is because one watt is equivalent to one joule per second.
To complicate matters, however, your electricity company measures the energy purchased by you, not in joules (or kilojoules or megajoules, etc.), but in a special unit called the 'kilowatt hour' -which is equivalent to 3.6 megajoules.
To find out how much energy your lamp is using, in kilowatt hours, you must multiply its rating (in kilowatts) by the amount of time it is operating (in hours). So if, for example, your 60-W lamp runs for, say, four hours, then the energy consumed would be (60/1000) x 4 = 0.24 kilowatt hours. From this, you can work out the cost of running your lamp, by mulitplying the number of kilowatt hours by the amount your electricity company charges per kilowatt hour.

What size fluorescent bulb replaces a 60 watt incandescent bulb?
You would need a 12 Watt flourescent bulb
Is a 35 lumens bulb as bright as a 60 watts bulb?
Lumens measures how bright it is, watts measures how much electric power it uses up. An old-type incandescent bulb produces about 10 lumens per watt. A halogen produce about 13 lumens per watt. A fluorescent (energy saving) bulb produces about 50 lumens per watt. LEDs produce somewhere around the same as a fluorescent.
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
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.
How much power does a 5 watt bulb use?
The bulb uses 5 watts of power.
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.

A fluorescent (energy saving) bulb produces about 50 lumens per watt. LEDs produce somewhere around the same as a fluorescent.
What parameters you consider when you calculate the current consumption of a 40 watt fluorescent bulb?
voltage, current and power factor
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
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.
How much power does a 5 watt bulb use?
The bulb uses 5 watts of power.
What is the wattage of a standard four foot fluorescent bulb?
35 watt
How many kWh will a 32 watt fluorescent bulb use?
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
What is a lumen How does it relate to watts?
A lumen is a unit of luminous flux, which is the amount of light emitted per unit time. A watt is a unit of power (such as electrical power), which is the amount of energy consumed per unit time. Light bulbs have ratings in watts, which measures how much electricity they use, and lumens, which measures how much light they give off. For the same kind of bulb (incandescent, fluorescent, LED, etc.), a bulb with a higher wattage will produce more lumens. However, a 10-watt LED or compact fluorescent bulb may produce more lumens than a 40-watt incandescent bulb.
Can you use 40 watt in a fluorescent light in place of a 32?
Yes, the wattage is just the power consumption. A 30 watt Fluorescent will give more or less the same light as a incandescent bulb or 60 watts, which is the limit for your fixture for incandescent bulbs.
Which among the following is most energy efficient incandescent build fluorescent tube compact fluorescent light bulb halogen bulb?
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
