Do these still exist? A15 base 3-way light bulbs

Looking for these for a lamp. Need to be 3-way, not dimmable bulbs with an A15 base.

I've had no luck locating them anywhere. Haven't had to buy one for several years.

In a store probably not but I am sure they would online. Tons of speciality bulbs online. You also might talk to a local lighting store. I ordered some rare bulbs i was unable to find online from my local place and got tons to have for the future.

A15 refers to the shape and size. What is the base you're looking for?

Most light bulbs are actually an E-27 base. There are still incandescent 3-way bulbs as well as CFL and LED versions. The LED versions are somewhat new and pricey.

3 way bulbs are generally physically larger, especially the CFL and possibly LED versions. I've never seen an E27 base A15 size 3 way bulb.

In my experience, the design of 3 way bulbs and sockets often results in a poor electrical connection which typically results in one of the filaments burning out very quickly. You might be better off with a plugin dimmer.

maybe it fits bigger bulb? if it's design for A15 incandescent, must have extra room, because of the heat.

usually LED bulb's glass part is not that hot, it's safe even the glass is touching the lamp.

or break the glass? most LED is safe to do so, just don't break the actual LED inside. i have a Cree bulb's glass cracked, i took the whole shit off. now it looks skinnier than A15

NO! It isn't safe to do that. To keeps costs down, most led bulbs have non-isolated power supplies and voltages present are certainly high enough to deliver a lethal shock. Some bulbs do use conformal coatings on the circuit board, but they're still dangerous.
