sorry man,you asked why and i gave an answer.i used reflectors for a few reasons,one was people on here saying you dont lose much and might actually gain it back at the bottom of the canopy.plus i seen mau5 using them lol.but then i saw the test results,AND bought a par meter.bare cobs put just as much ppfd on the floor as cobs with reflectors,and in a much more even spread.i see all kinds of hot spots with them on so i pulled em off and was able to raise my plants closer to the lights so win/win imo.only place im using them now is where i want to keep light off the walls in the corners.but anyhow,with the white angelinas on 3590 spaced at 11 inches you have a serious dead spot between cobs down to about 14 inches ,where the beams start to overlap its good again.but i do not see higher numbers on the floor @ 60inches from the cobs.i would not have even checked the floor if i had not read the sphere info.its a lose not a transfer like i thought.
