This is a model for a light bulb that I have never seen. Does somebody recognize this model?
You're trying to buy into a paradigm that doesn't exist
You've grown up with incandescent bulbs.  They blow out every 750-2000 hours, because they are basically tungsten on fire.  So you go &quot;that's why bulbs have sockets&quot;.
Then you learn about fluorescents.  The electrodes suffer spallation and mercury absorption, so they too eventually fail. That's why they have sockets.
You learn about HID, ditto ditto.
Then you learn about LEDs.  And you think &quot;Since incandescent light emitters burn out and need sockets, and fluorescent light emitters burn out and need sockets, and HID light emitters burn out and need sockets... therefore it follows that since an LED is a light emitter, therefore it burns out and LEDs need sockets&quot;.
But when you actually stop to think about that thinking... it follows a pattern, but there's not actually any logic to it.  What do LEDs actually have in common with those other obvious bulbs?  Nothing. Except they emit light.
So LEDs are a blank slate as to the question of whether they burn out.   And the answer is, they don't.
Therefore, nobody builds lights with replaceable LED emitters.
Meanwhile, in the real world...
LEDs do die.  And what they die of is driver failure.  The driver is the electronic module that regulates power to the LED emitters to keep them at the correct current.  (it's rather akin to a ballast).  The drivers fail because they are cheaply made Chinese, which was the only way the seller could hit the price-point which the buyer (that's you) insisted on.
Of course you have had failed LEDs, and you have fantasized that if only you could pry up the LED emitters you could replace them with good ones and the light would be back.  In fact, it's a Chinese capacitor in the driver that has taken a powder.  The LED is fine.
In many fixtures, drivers are standardized enough that a spirited search for a replacement driver module can turn up a workable substitute, and you can be back in business.
If you ask me, the darn drivers ought to have sockets and be standardized.
The only cases of LED failure I've seen which weren't that, was where the PC board itself and/or the lead-free RoHS solder failed. This was unrepairable, so into the trash it went. Ironically the FTC sent me a check refunding me the purchase price of that bulb; the company was that disreputable.
There's also a technical reason in the way
Like fluorescent or HID lights, LEDs are dumb and need something external to limit current. You can use a resistor, but you'll sacrifice most of the LED's performance if you do.  So most LEDs rely on an active driver that runs them right on-spec.
Driver specs are a specific exact current (e.g. 350mA) at a range of working voltages (e.g. 30-46 volts). (that voltage will vary depending on the LED temperature, age, manufacturing variations etc.)
The driver must be semi-custom matched to the LED. So if we had pluggable LEDs (or drivers), the plugs would have to be keyed so you couldn't plug a 350mA LED into a 700mA driver. Because that would go &quot;boom&quot;! Also, a 48-70V LED just wouldn't work on a 16-30V driver.  So we're talking dozens of key shapes.
Where that can work is 12V LEDs, because many of them use simple resistor drivers. I suspect that's what you have there.
Cooling is also a big issue.
When LED emitters run at peak performance, they need a good heat-sink. Just like installing a modern CPU, you have to use the heat transfer goop, and bolt it down very soundly onto the heat sink, with no real margin of error.  This is another barrier in the way of field-pluggable LED emitters.
