How do you tell what "type" of power a DC power supply is?

I ordered some LED strips that came with the best power supplies I could find on Amazon. Those were 12V 5 Amp models. There is one I am ordering tomorrow that is 24V 2.5 Amps.

The 24V models says, "Only for LED lighting." I know some of you have mentioned different types of DC power and supplies. I know I'm eventual going to mix them up, so what's the difference and how can I test them--or can I--to designate which ones are which type of DC power?

I can't imagine a power supply that only can be used for LED lighting.  Perhaps it's constant current or something.  Read the specs.

Yep, something like that. Just not sure what.

Possibly, it can be non-isolated from mains too, and have very weak or almost absent EMC filters.

Constant current vs constant voltage?

Switching vs linear?
