3-way lamp. A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage.
A 50-hour-life projection bulb, for instance, is designed to operate only 50 °C (122 °F) below that melting point.
