Mogul to medium base adapter converter. Works 3-way
Product Review (submitted on October 17, 2024):
A simple gizmo that does what it says it will -- allow a standard 3-way bulb to work properly in a mogul lamp socket. The price is right too except for the extra charge for shipping, but it's still a good option. I will caution anyone thinking of using a 3-way LED bulb to replace an incandescent 3-way mogul bulb to look at the shape of the LED bulb in the context of your lamp. Many LED bulbs flare out just above the screw threads considerably wider than the same spot on the old mogul bulb. If your lamp's opening above the socket is too narrow, those LED bulbs won't screw down far enough to make electrical contact. There are LED bulbs with narrower, longer necks, but you may need to search for them.
