The excess pressure from screwing in a light bulb too tight can warp the metal connection tab at the bottom of the socket of the fixture, creating a loose connection over time and causing the light bulb to flicker. This will ultimately cause the light bulb to burn out faster.

What will happen if you put a 3 way light in a one way socket?
Thus, if a 3-way bulb is screwed into a standard light socket that has only a center contact, only the medium-power filament operates. In the case of the 50/100/150 W bulb, putting this bulb in a regular lamp socket will result in it behaving like a normal 100 W bulb.
Can I put a 100 watt bulb in a 3-way lamp?
Screw base three-way light bulbs and sockets work by supplying power first to the low-wattage element or filament—the 30W or 50W or 100W element in the three examples above. It will then send power to the middle-wattage element or filament (the 70W or 100W or 200W element), and finally to both at once.

Do you need a 3-way lamp for a 3-way bulb?
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.
How do I know if my lamp is a 3-way?
Three-way sockets look very similar. The difference is that next to the metal tab at the bottom, there’s a third contact—a bit smaller than the metal tab and set slightly off center. That extra contact matches a small ring-shaped contact on the bottom of a three-way fluorescent bulb.
How does a 3-way lamp switch work?
A three-way bulb has two filaments in it. The next time one burns out, carefully open it (for example, wrap it in a towel and hit it lightly with a hammer) and you will see the two separate filaments. For the lowest setting, one filament comes on (it might be a 50-watt filament).
