hey man,just a quick reply from a concerned reader... those ufo getting sold are dirt as far as i read. if you realle wanna go led try wex-150 ,spectra,or another PROVEN LED LIGHT.
there is no easy way of doing this than to read up on finished grow logs to look for proof....(only look at ones there is 1 year old or newer! alot of bullshit out about led pre this period)
i learned the hard way, payed 600$ for a 450w light ,which ended up being 300w and never worked( thank you growlightpro,for a shitty light that never worked)

on another note,you will be happy that you choose to scrog, because the penetration on led is not always there, depending on what angle the lens is


i am far from being a compitent grower but trying to get there,but i am a very unhappy owner of a 600$ light that doesnt work so let me get you a tip on this subject


no GOOD LEDS are cheap. the diodes can be quite expensive themselves so you gonna have to pay. for 500-800$you will get a good light, and personally i would go with the spectra if i had the money to try again.
hope this helps....
p.s.try and get a hold of bigsby here on the forum,he helped me out,is very friendly and as far as i remember he grows with leds
