Light Bulb Lingo | 3-Way Bulb vs 3-Way Fixture
A 3-way BULB is a single bulb that looks like a regular light bulb. However, if installed in a 3-way socket controlled by a 3-way switch it will produce 3 different light levels. Low (40w equivalent), medium (60w equivalent) or high (100w equivalent). In hospitality this kind of bulb is frequently used in desk or floor lamps.
A 3-way fixture uses two regular bulbs in two regular on/off sockets controlled by a single 3-way rotary, toggle or push button switch. The first switch position turns ONE bulb on. The second position turns off the first bulb and turns on the OTHER bulb. The third position turns BOTH bulbs on. In hospitality we are used to seeing this situation on the wall or nightstand between two beds. Both bulbs can share a single shade.
3-way bulbs are NOT dimmable.
A 3-way bulb in an on/off socket controlled by an on/off switch will produce a single light level.
An on/off bulb in a 3-way socket controlled by a 3-way switch will produce off/off/high light levels.
