One of the reasons they are so much cheaper (aside from the obvious reasons) is that they are not true Constant Current LED drivers. Note that they are “regulated power supplies”, which is not even close to the same thing. LED’s really need a Constant Current or CCCV power supply to function best. Regulated will work, but not as well as it could and not as safely. You will notice drifting ans there is a real chance of thermal runaway if pushed hard.
Not saying you cant do it, but its far from best practice.
