It is with a heavy heart that I tell you, I've owned a Pro Grow LED before, it was awful, and I returned it within a week.
I'm sorry, somebody had to tell you.
If you have been following any of the grow journals they give links to, or watched the "Propoganda Pharms" youtube channel, they're not legit.
I made the same mistake, too, so don't feel bad.
I would recommend reading threw a few of the threads in this LED forum, as we are the most knowledgeable, and experienced LED growers out there.
I would also recommend looking into Area 51 LED grow lights.
Good luck.
