I've found a company tht sells outdoor led lamps, one of these seems interesting:
16200-18000 lm
3x60W Epistar/Bridgelux
2700-6500 K RGB
120° angle
IP65
They say tht is efficient like a 450W HPS what do you think about it?
Would this power 4 cxa2530? http://www.mouser.com/Search/m_ProductDetail.aspx?Mean-Well/ELG-100-C700B/&qs=MzdiiTx5rGxZPwBsCAUAog==

Plants need at least 500 PPFD so the real question is what is the PPFD?I've found a company tht sells outdoor led lamps, one of these seems interesting:
16200-18000 lm
3x60W Epistar/Bridgelux
2700-6500 K RGB
120° angle

im guessing its not enough.
Why if 2 Cree 100W each can be enough, 3 Bridgelux 60W each isn't?

heres the thing Alex, each cree COB has 136 diodes on each chip &
bridgelux only has 25 diodes on board so you do the math
So u think with this and 2 SS i won't even reach 3.5 oz ??

that floodlight might grow an oz of larf if ur lucky, dont waste ur time or money is my advice.
Ok so i'll take 2 x CXB3070...do u think 2 x Cree LMD600 (1.7A 102W) will be enough to light em up? Or maybe is cheaper and enough 2 x Mean Well OWA-60U (1.5A 63W)?
Hey there. I'm about to start my first grow. Was looking for feedback on these lights. http://www.betterledgrowlight.com/article/186.html
I'll be using a 4x4x7 grow tent and growing 5 plants in said tent. I'll also be using two of these lights if I decide to go that route.
Im just looking for overall opinion on the lights. I was told they have the Cree chip inside them as well. I'm not sure how to check that though.

I can put you in touch with someone who will make you a very good COB CXB3950 light if you are interested.

Hey RiU,
Long time luker here finally posting. Love the this subsection of the forum. A lot of really knowledgable people doing remarkable things. Ive got a 4x8x7 foot space that im looking too cover. Height and ventilation are my main concerns. I plan on making my own panel but im in a time constraint atm and would like to buy a prefab fixture. Ive narrowed it down between either 2 Heavenbright CXB3590 Motherships or 2 OpticLighting CXB 500 watts. Do you guys think that will be ample coverage for this grow area? And feel free to offer up any suggestions as im open to all!

Yes, two of either would do. I would get 4 T4-1750s from TastyLED. You'd get a better spread and at 53%efficiency.
