I have the 600w Pro Bloom Tyrell. I am happy with it too. I'm using it on a small hempy grow (not journaled) presently in flower. I use a 1k HPS for my main 5x5 tent grow only because the area of coverage isnt there with one unit. I would need to run two units for my grow area and the $$ just aren't there atm. But that's my fault, not the lights. I can also say they back up their lights well with customer service.
