Are Samphon lights trustworthy?

I’m looking to set up a somewhat larger grow room (compain anticipation of a fully commercial grow operation in about 6 months. Samphon lights seem to have pretty comparable ratings to more expensive options and come with a 3 year warranty, which is pretty decent from what I’ve seen.

Does anyone have experience with this company and their lights? I’m looking to buy at least 10 so I want to make sure I don’t make a stupid decision.
