To be honest I wouldn't actually recommend any of the cheapest quantum boards.
Even if I didn't find stuff that violates international safety standards (eg more than 30 volts AC rms, 42.4 volts AC peak or 60 volts DC exposed without proper ingress protection), I was finding obviously fake safety labels like one that claimed to be double isolated (square inside a square symbol that should be a plastic case) yet had an external driver with a metal case. Stuff like this makes me wonder what's going on inside the driver if the maker is so quick to put a fake label on.
I also found bogus "CE" marks.
As an electrician I can't recommend stuff like that and use higher quality lights myself if I'm not DIY my lighting.
For cheap lights the safest option I've found so far that puts out high amounts of light are the PAR38 lights. Something like this is 25 watts for $5 but PAR38 has a narrow 40 degree beam pattern so you would need a redesign.
