I can't say enough about how dishonest their claims are, imho, as well as the shill reviews and fake "customer journals" (almost certainly from employees) which is typical of how the actual chinese manufacturer operates.
Outdated and weak 3w diodes. (5w diodes have been out for 4 years or so) VASTLY overstated coverage and yield claims. "Almost zero heat" claim is pure bullshit. No actual draw specification. (why are they hiding that?)
It's so bad that I'm thinking about blacklisting/deleting all posts about these lights...and the company that makes them as to not advertise anything about them anymore.
You didn't say what you planned on growing but my advice is to seek a more reputable manufacturer and a better quality light with at least 5w diodes (if you plan on going with LED) unless you're growing wheatgrass, algae or something terribly short. Even then I'd pick a different light/company if it were me.
YMMV...
Disclaimer: I still use HID and I'm NOT an LED expert. All of my LED knowledge is from other parties or research so I can't say from first hand experience one way or another. I also run a medical grow consulting business in SoCal.
