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.

Do light bulbs emit light or suck dark?
Light bulbs emit light.
What is The electrical power used by light bulbs measured in?
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.

What do you measure in light bulbs?
Light bulbs are measured in two ways: Lumens for their light output and Watts for their power consumption.
Do higher wattage bulbs give a brighter light?
No. All light from light bulbs (incandescent) are equally bright. Higher wattage bulbs simply produce a higher quantity of light measured in lumens.
