You'r real problem will be heat dissipation, if it is not enough you will gradually fry any LED.

I use a bank of 10W COB LED strips on a dimmer with loads of heat sink and they have been very reliable.

Should be fine; it's just an array of densely-packed LEDs.

The truly scary thing is how much power you can now get out of a single LED. My two-year-old laser cutter uses a 2.5W LED laser, and I have another in my lab that's 6W, but now there are 50W LED lasers: https://www.rpmclasers.com/output-power/50w-lasers/

That is insane.  Also somewhat scary.

They look pretty good for the price. You can test this supplier with low power models and if they come good you can order the big boy.
