There really close as far as I know bro mine are going back next week to have the secondary optics (or reflectors)and face plate fitted as this grow has been done without,this really excites me as these 1w Luxeon upgrades have done a better a better job in flower than a standard MS with 3w chips and the light directed into a 90 degree beam,I believe the angle on the primary optics of the Luxeon chips is 160 degrees hence the light bouncing off the walls.
