3-way lamp The two filaments can be activated separately or together, giving three different amounts of light. A typical 3-way incandescent bulb is a 50 W / 100 W / 150 W bulb. It has a low-power 50 W filament and a medium-power 100 W filament. When they are both energized at the same time, 150 W of power is delivered, and a high level of light is produced.
