Looks like a barrel plug. These are very common and finding s as replacement should be easy. On the underside of the lamp there will be writing that says what the electricity requirements are. e.g. 12V—-400mA Look up a replacement using those numbers.
It doesn’t say anything on the lamp but I think I can find that on the amazon listing. Thanks
If you know the lamp model number or manufacturer or anything like that you could possibly find the specs online somewhere. I think they also sell some "universal" type barrel plug power supplies that come with various sized barrel connectors.
Ah yes, you must mean the biblically accurate universal barrel plug adapter.
Edit: I had something like this guy growing up and used to use it to make sparks and other shenanigans.
What utter goofball was it who ever built a device with reversed polarity?
Some Chinese devices come with reverse polarity.
Your best bet is to find a universal charger. They sell chargers with like 20 barrel tip sizes.

One thing to remember is that the Voltage needs to be exact, but the supplied Amperage can be equal or higher then the original power supply.
So if you are trying to replace an originally 12v 400mA power supply you can also go with a 12v 500mA or 1A (1000mA) power supply. But 12V 200mA probably won't work and for example 19V 400mA might outright destroy your device.
