The reason I'm saying that is because those Panorama pro and Stunner led are pretty powerful they need at least 60 W the one you posted is last then that if you don't believe me just call the company and ask them yourself and see what they say
If the company one is 60w and 24v dc then with a little math you figure out the amperage is 2.5A and there you go. The link below is 24v at 2.5A hope this helps.
I don't see any problem with using other than manufacture recommended power adapter if all the specifications are fine. I know some people who use those kind of adapters on other LED lights without any issues. The only problem I see is reliability of non-brand products. For $11 instead of $36 why not give it a try and monitor closely how it performs.
