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.
Incandescent light bulbs are generally measured in watts, indicating the power consumed by the bulb.
The amount of light of light produced is measured in lumens. Fluorescent bulbs produce more lumens per watt than incandescent. LED lights produce more lumens per watt than florescents.
Light bulb power consumption is measured in watts.
Watts. The watt is the standard unit of electrical power. See Wikipedia link.
Watts is the usual unit but Lumens would be a better guide to the light output. We are unfortunately stuck with Watts for historical reasons.

A: There is no such a thing as simple circuit if the bulbs are put in series the light will dim if put in parallel both bulbs will light up the same provided the source can sustain the power increase
It doesn't 'USE' any; that is, you don't have to provide any electromagnetic waves in order for a light bulb to do its job.In the course of doing its job, the light bulb PRODUCES light and heat waves.A fluorescent light also produces radio waves.
Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.

Heat bulbs would be a more appropriate name because incandescent bulbs transform 90% of electricity received into heat and 10% into light. New Compact Fluorescent light bulbs use only 20% to 30% of the energy needed to power a standard bulb for the same wattage.

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".

watts
Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.
