LED Edison bulbs or not?

There may be wattage/voltage rating engraved on the metal base. 15 watts or higher is incandescent. Do they get warm when on? If so, they are incandescent.

Edison refers to the E26 base. Edison base lamps can de incdescent, halogen, CFL or LED.

I like installing and using the Edison base LEDs. I'm guessing with the millions of fixtures out there that there will be replacement bulbs for a very long time.
I have had to buy for specific applications the fixtures with built in LED elements and if they fail the fixture would probably need to be replaced. Long warranties mean nothing 20 years from now.

And that should be the reasoning of everyone doing an LED upgrade. I bet many brands and styles of 'replacement' units will be obsolete in 5 years or less.
A system designed to consume will want you to buy all new as soon as they can force it.

I have to disagree. Use of a LED Edison based lamp of any kind in a fixture designed for incandescent lamps is inherently inefficient. LED fixtures are designed to take advantage of the directional nature of the LED and focus the light where it is needed. You are wasting lumens sending them in directions that are not useful with an Edison based lamp . Additionally many Edison based LEDs do not last in fixture with enclosed globes (heat buildup).
I would use a LED in an existing fixture but would never buy a new Edison base fixture to use with LEDs.

Usually you put that style of LED lamp (that is made to look like a filament style incandescent) in fixtures where the exposed bulb is decoration. Like a chandelier or clear glass cover, which is why the bulb glass looks "vintage" and gives a very soft warm light. They're a bit more expensive than your basic LEDs.
FWIW the current technology of most LEDs has mitigated the heat dissipation within the lamp on the lower wattages. On higher wattages you will see vents on the lamps.

I like those old-fashioned style LEDs, I find that they are the most 'dimmable' LEDs that I have come across, and they all seem to be a nice warm light, in fact some of the glass bulbs are amber tinted. Downside, the long strings of little LEDs inside are quite fragile and you can break them if you drop the bulb.
OP the lack of embossed data on the bulb base strongly suggests cheap no-name products from a certain country which is definitely not a currency manipulator and had zero Coronavirus cases last week.
Also many of those fixtures insist on having a totally enclosed globe. Which plays great with incandescents because they love hot places like ovens. But is very hard on LEDs.
No doubt. The burden of those fixtures, however, is they must be built to support incandescents, on the off chance some "cold dead hands" type insists on sticking a 100W incandescent in there. This limits the elegance of their design.

Well, the theory is that the LEDs are supposed to outlive any of us. And the LED emitters certainly will. The problem is the electronic driver that converts mains power to constant-current for the LED, made with third-rate capacitors and RoHS solder.
It's sad that we're reduced to "find that"s and "seem to"s by lazy sellers. The seller should be plainly stating all that info - dimmability, CRI, color temperature - right on the package and on the sales webpage.
I say LED... I bought them for one of my bathrooms. https://www.amazon.com/gp/product/B07JZSD14P/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

Yes.
But does the pictured lamp employ a driver? Where is it? Got the URL for a teardown? Those long strings could add up to 120V all on their own.
Thanks,

Google "watt meter rental at library" to see if a library near you lends watt meters out. If there isn't one available locally, maybe a meter can be sent to you. They are not that expensive but rarely used, so the purchase is rarely justified but then again. Other options are to purchase one at a local hardware store, or to order one from banggood.com (make sure its plug is made for your wall outlet and its outlet matches your wall outlet).
Well, this is misleading, at best. Yes the design relative to optimal might be "inherently" inefficient, but LEDs are "inherently" efficient, which trumps the fixture issue, by far. You're really muddying the waters here. Since the whole point of this style of bulb is to look a certain pleasing, nostalgic way, using a contemporary LED design is counterproductive.
Using an LED bulb given the desired scenario is WAY more efficient than using incandescent bulbs.
