I dont know i sorry some idiot changed the answer it was a awfull answer so please dont get up set about not finding ur answer....
Light bulb power consumption is measured in watts.
Watts, it is the product of amps x volts.
The electricity used is measured in watts. This is equal to 1 Joule of energy per second.
This generally corresponds to the amount of light produced, measured in lumens.
watts
Most light bulbs waste energy as heat. Even LEDs. Large light bulbs require more power.
Anytime you ask electricity to do anything for you. Turn on light bulbs, start a car, run ann engine, watch TV. Anytime electrical power is used.
There is no such thing as 'electrical power' or 'mechanical power' or, in fact, any other sort of power. Power is simply a rate -the rate of doing work. In SI, power is measured in watts. An obsolete unit of power is a horsepower. Although, in the Unites States, the power of an engine is usually measured in horsepower, elsewhere it is measured in watts (or, more usually, kilowatts).So, when an engineer describes converting electrical power to mechanical power, what he actually means is the rate of converting electrical energy to mechanical energy.
In physics, power is the rate at which energy is transferred, used, or transformed. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine). For example, the rate at which a light bulb transforms electrical energy into heat and light is measured in watts-the more wattage, the more power, or equivalently the more electrical energy is used per unit time.

The power of light bulbs is measured in
The amount of power they consume is measured in watts. The amount of light they put out is measured in lumens.
Electrical power of a bulb is real power used by the bulb. It is measured in Watts. In general, the higher the bulb watt rating, the more lumens it will produce. This is not always the case, since some bulbs are more efficient than others at turning electrical energy into light (ie some bulbs produce more heat, an unwanted byproduct, than others). Real electrical power is always measured in watts. Total power (real and reactive) is measured in volt amperes, which is a vector summation of real power plus reactive power. Power times a time it is used is measured in Joules, or watt seconds.

It is measured in watts.
Light bulbs are measured in two ways: Lumens for their light output and Watts for their power consumption.
The electricity used by a Lightbuldb is measured in "Watts", the output of the Light (i.e. the Light) is measured in "Candela".

Electrical power is measured in watts (W), just like any other type of power.Power is the rate at which energy is used. Energy is measured in joules (J), though utility bills usually measure energy using kilowatt-hours (kW·h) instead. 1 kW·h = 3,600,000 J.
