I misspoke, let me make a correction.Just for my own knowledge, you wouldn't happen to know where to find the write ups on those grows, would you? Space isn't really the issue since I have an entire room I can devote to this. I'll be using Panda to wall off the space necessary. I'm more interested in what plant configurations are reccomended with these light bars. I'm highly interested in LST and/or Scrogging, however this being my first grow I'm still wieghing the pros and cons with the risk involved.
I use DS XML 350W to cover 4x4 grow space with great results. They are $997. http://www.diamondseriesleds.com/ds-xml-350/Searching for KIND LED's yields to much sifting. I know the regular recommendations Area51, Hans, Apache Tech, Cree Globes, Black Dog, DIY so where do these fair? I have a 4x4 flowering tent I would like to do for the best bang for the buck. Currently I am sold on 2 XGS-190's for about a grand. So when dumping that type of cash I try to research as much as possible. So opinions on 2 L300's. Pricing is comparable. I prefer 2 smaller lights instead of a single light for flexibility and in case one dies I can use the single till the replacement arrives. Thanks in advance.
That's a new one to me. I would get the 2 150's if I went with that brand as I prefer smaller for more options of use or not use. So that said comparable pricing to the "popular" brands. Any grow journals using them?I use DS XML 350W to cover 4x4 grow space with great results. They are $997. http://www.diamondseriesleds.com/ds-xml-350/
Good info thnx. Checked out the specs on these. The reds were about 25% efficient, deep reds 25%, royal blue only 21% and blue similar. The whites would have been abysmal, 12-15%. The numbers in actual use might be lower because the specs sheets are based on Ta 25 (ambient temp). I suspect they simply pulsed the emitters so these numbers have not been corrected for Tj. With efficiency this low they would be pumping quite a bit of heat into the small heatsink so we could assume a very high Tj 85-100C? That could knock another 20-30% off the output in the specs sheets, especially hard on the reds.heres the bins for those who own the 2012 Area 51 panels, they are powerful, just dont spread as nice as the SGS, and I am sure XGS.. (the distance between diodes, goes a long way.. and withholds intensity w/ Cree's)
Red (630nm)
Part#: HMHP-E3HR
Luminous Flux Bin: VO
Spec. Bin: BO
Deep Red (660nm) - only used for so long as stock lasted, then went to the 13:2 (w:r)
Part#: HBHP-E3LR
Radiom. Power Bin: QO
Spec. Bin: AO, BO, & CO
Royal Blue
Part#: HBHP-E3LB
Blue
Part#: HMHP-E3HB
Luminous flux Bin Codes RO and EO (respectively)
And yes, Area 51 did NOT use Monochromatic blue's in their 2012's..
These blues were encapsulated by Heliopto to make their 5900k (cw) using GAL520 and RR6238 Intermatix Phosphors,
The 4250k had a range from 77-90*F, depending on where I was at on the fins, 84-86 being typical..SGS-160 - I am assuming these top bins.
The XPG 4500K R4 bin @ 700mA Tj 50C - 32%
The XPE 630nm red P3 bin @ 700mA Tj 50C - 42%
Those are decent numbers in terms of efficiency but Tj is probably closer to 85C. I would love to get your ambient and heatsink temps thnx! Richelsdorfite ran the SGS and Hans numbers in the Astir thread but he was taking it a step further and looking at total system efficiency including reflector losses and driver losses.
The number of plants in a tent is directly correlated to available space, light footprint and time allowed/desired for vegetative growth. You can choose how many plants to put in the tent, and adjust your veg time accordingly. 12 is doable, basically clone to flower with virtually no veg, or a similar approach from feminized seeds. Under HID you could get 1/2-1 oz from each plant depending on genetics using this method. Under LED, your guess is as good as mine. Its referred to as SOG (Sea of Green). The idea is to grow small plants with little to no veg times and fast harvests consisting of all top nuggets. Beware that most states make it difficult to operate within legal limits for medicinal growing using the SOG method!So I have decided to get 2 ar51's 190's to place in 36"x54" flowering tent. I am growing soil. What do you think is a realistic amount of plants that I can flower in there. 1 plant per sq ft is 13 so maybe 12 but damn that seems high. I am a noob so be gentle. Thanks
In your grow space, I would veg 5 plants (clones or seedlings) for around 4 weeks, top once, and flip to flower.So I have decided to get 2 ar51's 190's to place in 36"x54" flowering tent.

Bonsaihero, also known as Hans panel is very great. So you have spent 630$ at three of his 65W, and right now are going to spend another 500$ to take 2 of his new 85W panels, it is a lot of money, if I were you I would ask Hans a discount~ What's the size of your growth tent, why are you going to put so many high efficient panels in it? Do not cook the sexy ladies, anyway...
Wanted to post some new info about bonsai hero.com : Hans put out a new 85 watt panel, kinda bummed I bought 3 of his 65 watt panels about 3 to 4 months ago. Well needless to say I'm coming into some money here in the next few weeks (with the help of his 65 watt panels I might add) so I'm gonna order 2 of his 85 watt'ers and add them to my existing 3 65 watt hansled's and have more light than Zues himself
