So how do 3-way bulbs work?
In general, standard single-filament light bulbs only use a single switch to set the filament to work. But 3-way bulbs will work according to their rated power.
For example: 30W/70W/100W or 50W/100W/150W. You'll see that the first two numbers are the sum of the third number when you look carefully.
The 3-way bulb has the same screw-in base as the standard bulb. After screwing the light bulb into the base, one turn of the switch only illuminates the low-brightness filament, the second turn illuminates the 70W/100W, and when the switch is turned for the third time, the internal components work together to turn on the brightest filament.
Where are 3-way bulbs usually used?
Generally, there are more households, such as ceiling lamps and floor lamps, which all use 3-way bulbs. And they're so easy to buy, you can find a variety of different 3-way bulbs at almost any bulb retailer.
