Fantastic light. Had to mount driver outside the tent to control heat. May decide to bring back in during the colder seasons. Hard to say if I'll ever go back to Blurple, but perhaps running them in tandem would be beneficial. Buds were nice and tight w/o CO2 - not as tight as an HPS but if this light is any indication of the advancement in LED Tech, they're getting real close! For a 150W power draw, I'm happy.
