[hope that was a sincere question and not a protective come back]
wish i did..but have already made 2x more lights than i am using..it was fun..kinda
i have similar[maybe not as good] but they are growing lettuce..day in day out for years..at my bro's place
i however,i have privy to a private canna website where one of the guys uses one and it does darn good
it was an eye opener
and its like 8 x cheaper[no exaggeration] than those "other ones "here..
we wuz rong in a few ways about burples..
but we wuzzint rong about the seller here's gear being hideously over expensive
and not gonna yield 2x as much.
but throw enough photons at em and there yah go
jsut like the cheaper chinese panels being as good as the higher bin ones if you move it 1/2 " closer
the 561 b's i first got by mistake still grow well
and dang..
those no lens/no reflector cobs probably do better than panel's but enough panels
preclude using heatsinks
and i said Galaxy..not any of the others because i have seen the threads
i cannot vouch for any of the others you mentioned
why are you defending so much. bro?
you were supposed to be impartial
