WebLight bulbs are ranked by their power-- the amount of light they put out in a certain period of time (measured in watts).Higher-watt bulbs have a bigger filament, so they produce more light. A three-way bulb has two filaments of different wattage -- typically a 50-watt filament and a 100-watt filament. The filaments are wired to separate circuits, which can be closed … WebIncandescent lightbulbs produce light when electrons (electric current) move through the filament and collide with.
