On their website these fixtures are UL certified. It even warns you that other LED fixtures are not UL certified so at least the MarsAqua are.
I happened to open one of the 300w fixtures and build is quite good for a Chinese manufacturer. Case is solid, glass is sealed quite well to prevent moisture/salt from getting inside. Drivers are in harnesses for easy replacement. LED panels was nicely assembled.
Did you do any modifications to it? I was thinking to add some 420nm UV but after I read more new studies on coral photosynthesis wavelengths I decided not to modify my unit and keep it as it is. Also I know licensed electricians here who are also reef tank keepers owning this fixture and they assured me it's good and also perfectly legal with no issues whatsoever. Of course I cannot speak for other countries and states or Planet Quebec...
Also I have no doubt high end LEDs fixtures are more efficient, slimmer, lightweight and all, but like I said, to me personally it just comes down to light good for corals... that's it.
