Not to piss on anyones bonfire but am i i reading the specs from the web right?!?
Ppf 87ish
Wattage 83ish
Ppf/j: 1.05ish
That is not very good at all. You would literally need almost 1000 real watts to light a 3x3 with those numbers. About 20% efficient when quantum boards are edging towards 60%.
Maybe the details of the specs is not right. Very nice spectrum though. But you could diy something very similar with vesta strips for about 0.50$/watt.
I dont want to sound like the usual nay sayer here but are you really sure about your purchase? Its a very expensive light, with no details on components and whoever manufactured it seems to have either fudged the numbers (red/blue/green ratios looks very off in comparison to the presented spectrum), and on top of that the mfger doesnt even realize that the specs/data from his web looks like he is selling a light almost 3 times as inefficient as what youd get from any riu-sponsored advertisers. Does he even realize how bad those numbers look?
Also, the returns policy seems very iffy, make a photologg and put details of evrything your putting into your plants etc: sounds like they could litterally deny you return due to anything you did, or didnt do.
I may very well be wrong, im only basing this on the specs provided by their web which might be wrong, but i hear buyer beware all over these lights.
Best of luck
