The power of light bulbs is measured in
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.
The amount of power they consume is measured in watts. The amount of light they put out is measured in lumens.
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.
Electrical power is expressed in watts or in jouls per secondAnother AnswerThere is no such thing as 'electrical power'. Power is simply a rate: the rate of doing work. Power can be measured in watts (in the SI system) or in horsepower (in the Imperial system). There is no reason why the power of a heater can't be measured in horsepower or the power of a car can't be measured in watts.
Electrical power is measured in watts. In an electrical system power (P) is equal to the voltage multiplied by the current.P = VxI Watts = Volts x Amps.
The amount of electrical energy it uses in a fixed time is the power, measured in watts, that should be marked on the light bulb when it's bought.
James Watt measured electrical power
the unit which are measured for power of lights are watts....
The electricity used by a Lightbuldb is measured in "Watts", the output of the Light (i.e. the Light) is measured in "Candela".
