well....U tell me bro.I dont know how many journal titles Ive seen that say"1000w hps going for a pd!!!!!"that seems to be a benchmark for alot of people.I got what looks like a little over 1 pd per light with just about every problem you could have in 1 grow lol....so I cant speak for other led lights but these, in my honest opinion will produce better than a 1000w hps.go back to where I posted the specs on these lights bro,they are all 3 watt top bin Helixeon diodes.not to mention they have 4 switches for different stages of the plants life.the first switch is for seedlings,the lights run at 150 watts,turn on the second switch and they are for veg.with 2 switches they run at 300 watts.turn the 3rd switch on for the first month of flower.with 3 switches they run at 450 watts. and then all 4 switches on for the rest of the flower stage,they run at 595 watts on full power, so you save quit a bit of money with them.So yes....imo they are the best option out there. I am confident that once I figure out all of the differences of growing with led's and the best way to train the ladies for my screen that I will get the 2 pds per light I am determined to get
hope this helps bro.
ps: the specs are on the first page
