Bro I dont know the tech stuff all I know is they work. All that info is on AFN in cobshop section. There's growers growing photos also. I like the autos hell I grew a huge one over 26 oz one plant under 300 watts
I have both Autocobs and a Timber Vero gen 7 400 watt and its collecting dust along with my Mars and Higrow blurples . I use only autocobs / Mega Crop with kick ass results
