Anyone used these lamps for flowering? I know the life of theses bulbs is around 3000 hours but what im thinking is that as theyre high intensity which should give better penetration to the canopy that what CFL would do. Im thinking of rigging up 4 (210w) over 2 plants which works out at 18-20,000 lumens, what do you think guys ? Do you think this would out-preform 2x125w CFL ? Peace.
