as soon as that white light bulb warmed up,those two leds were put to shame.im in a 8 x 4 tent,I can't imagine what 3 of these would do to light up that space.two will light up better than two 600 s,there really ,really bright.i need two nice vertical bulb reflectors.was gonna go for round parabolic style.only thing is ,there huge.have you seen those wierd looking wave reflectors?think there vertical too.
I don't know,any ideas appreciated guys.
bare bulbs was my first idea?was told no,no buy my grow shop dude.never seen a bare cmh bulb grow yet?
