Seems like some on each side of the debate have an agenda.
For a 4x4 space you should probably get 2 smaller LED units instead of one super/big one. Like I said, if my tent had been that big I would have gone with 2 Spectra 2011 240w units which is what Irishboy is doing (I don't know if that is how big his tents are but he is going all Spectra 240w units). And those lights actually draw 240w, a lot of companies will call their units say '300w' and yet they only draw 150w which really makes them only a 150w unit. You gotta watch out for that, it seems Blackstar may be misleading people this way (at least with some of their models?)
I agree 100%, interlacing the spectrums is key. I'd go with multiple panels like I am running, works awesome.
This is what i wanted to do really. use two kessil magentas for lower canopy and side lighting for true penetration and a blackstar ufo blue/white for enhanced spectrum. and a 126w penetrator or 120 watt grow led hydro. The seem to be competitors. I am going to run a journal on here in march. and i will be using 3 diff companies. as i believe some ppl do have agendas. there are reps on every forum. just the way it goes. Not that big of a problem, cuz you can usually smell the bullshit right away. something about how someone types...too formal...smells like bullshit. especially when numbers get thrown around. but you have to stay positive, it is the internet. For every road their are pot holes and police, you just need to know the back roads. you learn that from experience, research and a map.
I don't think you should go below 200w for spaces 2ft x 2ft or larger. I hear a lot of good things about UFOs and Blackstar. The only thing I have against Blackstar is they appear to be misleading people about the true wattage of their lights (or maybe that has more to do with who is selling the blackstar?)
Does the 240 Blackstar actually draw 240w from an outlet or around half that? I don't doubt they are good lights but I have doubts from reading posts about people with blackstars that were running at half power. And that wouldn't be because of a defective unit, it would be because they are getting the sum of the wattage of the LEDs and not the actual draw. As in a '300w' light has 100 3w LEDS, in reality though they can only run at about half power which means such a 300w light may only really be a 150w light. Some companies mislead this way and others don't. I think Blackstar makes good LED lights but I think they are misleading people this way.
Actually if you check out their sister site, monorad a forum dedicated to growing with their lights (non-bud). http://www.monorad.com/forums/viewtopic.php?f=6&t=75
Thats the right way to put it, I just couldn't think of the way to phrase is properly.
If the LED actually draws 400w of power then it should be too good to use on mothers
