Do you need a 3-way bulb for a 3-way lamp?
A 3-way lamp requires a 3-way bulb and socket, and a 3-way 2-circuit switch. Unlike a lamp controlled by a dimmer, each of the filaments operates at full voltage and the normal temperature for an incandescent bulb, so the color of the light does not change over the three steps of light available.
Can I use a regular light bulb in a 3-way socket?
You can safely operate a 60, 75, or 100 watt regular bulb in a 3-way lamp, assuming it fits on the socket. It will not harm the lamp. Just keep in mind that you will be effectively turning your 3-way lamp into just a regular lamp. The 3-way function will only work with a 3-way bulb.
What is a 2 way electrical switch?
In a two-way switch, there are two, one-way switches combined in one. One of the terminals can be connected to either of the two, but not both at the same time. The advantage of a two-way switch is the ability to control a single device from two separate locations.
Is dimmable the same as 3 way?
No. 3-way bulbs have three separate contacts to allow a three-way switch to power different incandescent filaments, to switch powers between three levels. Dimmable means that you can use a dimmer switch (replacement for a regular wall switch) to adjust the light intensity gradually across a wide range.
Are 3 way bulbs being phased out?
