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.
Depending what your measuring for, they are usually measured in watts just as any other light. However, you can measure them in candles and temperature as well.
why light bulbs are fragile
Light bulbs emit light.
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.
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
The power of light bulbs is measured in watts (W), which indicates the amount of energy consumed and the brightness of the light produced. The higher the wattage, the brighter the light emitted by the bulb.
The amount of power they consume is measured in watts. The amount of light they put out is measured in lumens.
Watts.
Watts
The electricity used by a Lightbuldb is measured in "Watts", the output of the Light (i.e. the Light) is measured in "Candela".
Light bulbs are measured in two ways: Lumens for their light output and Watts for their power consumption.
wattage or watts
It is measured in watts.
Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.
The brightness of light bulbs is typically measured in lumens. Wattage can also be used as a general indicator of brightness, but lumens provide a more accurate measurement of the actual amount of light produced by a bulb.
Yes, in general, higher wattage bulbs produce more light than lower wattage bulbs. However, the brightness of the light also depends on other factors such as the type of bulb (incandescent, LED, etc.) and the design of the fixture.
