Your video is stating Gavita is double the light to the crop of the EPAP, this is done by the reflector. same lamp. Your stating that yours blows away the EPAP (how is this possible you ask). Lamps are made up of different gases so that mixture is changed to change the outputs, no one is reinventing the wheel here, just making it better. reflectors are also decided by light plans that take certain things into account, height above crop, uniformity needed, etc....... AGAIN PL and GAvita are two of the leaders in lighting crops. PL has been in the business over 36 years, not sure how long gavita has been doing it. I can't vouch for a small basement grow, just larger MJ facilities I have seen.
