Hi,
I really appreciate your guys input regarding the 4X CXB3590s. However, I am yet to get a recommendation for the 4X CXA2530s. I am looking at HLG-120H-C500B. What do you guys think?

Bonjour
Idk a cob panel commercial company in Asia...but I know that www.cutter.com and @welight could tell you more have a cree cxb 3590 mounted on a hs with a fan you just need to plug some to a driver and the fan to a 12V psu that's it...it is not already made but the big job is done...you just need a bunch of wago with a leverage and a few wires to plug it in series or parallel depend on the driver you will choose!
But this combo cxb hs fan look nice for you...but you can't add lens or reflector with those so if you spray yoir plants with those you will have to do it outside the tent!

Bonjour
I already talk to Mark, and he asked what specification do I need
Its a 10 x 5 tent I was planed on using 3 600watt HID, as i already got two fo them. I dont think Im going to throw all those brand new HID i just paid. so I think Im going to have 2 600s hid with 600watt LED. or what would you think its best for me. cuz I plan on get rid of hid, if LED can have better result. would you recommend all chips with 3500K
could you pls give me some advice for the specification that fit my grow.
Thanks and have a nice day

Incorrect. Take a look at Cree's tool before giving advice, it is useful for getting up to speed - http://pct.cree.com/dt/index.html

At 1400mA CXB3590 has a Vf of 34.84. So 34.84 x 4 = 139.36.

1x HLG-185-C1400 is perfect for 4xCXB3590.

This page is fake.Today, I communicated with the manager CREE and Flux DD(14000) CXB3590 does not exist.
1400mA =200,8 lm/watt it is nonsense.
Cree CXB 3590 has eight variants in one color temperature.

It's not fake.
You just should not use a bin that the CXB3590 in that specific colour temp does not have.

You can look up what bin in the datasheet and part #
http://www.cree.com/~/media/Files/Cree/LED-Components-and-Modules/XLamp/Data-and-Binning/ds-CXB3590.pdf

The highest bin for a 3500K 3590 is CB which is flux 11,000 @85 degrees @ 2.4A 36V

But a DD bin currently isn't on the market, highest is DB which is flux 13000.
DD is for future bins.

DB has 70CRI for our purposes it is better to 90 CRI 3000K. Photosynthesis occurs at 660nm.

Who ever mentioned DD bin? We know DD does not exist. Everyone uses CD bin now and soon DB. The page is not fake. :roll:

Anyway the question was about using 4 CXB3590 on that driver and you can.

Guys
Takeaway here is never use PCT in isolation from Cree Datasheet for specific led. The PCT never relates to colour temp, only flux bins so you need to know from the datasheet the max flux bin for a given colour to then be able to work out all the PCT data LPW,vf, watts etc
Cheers

I could definitely use some help. I have a plant I been growing under a 30w CFL equivalent to 150w. It has been going pretty good, I just started a new one with the same bulb and I order an LED bulb to try with the new plant. Would this light work all growth or should I add it just for flowering or should I use both LED and CFL. I'm not going for gold but just trying to grow a decent plant.

Hi I just built a 12 cree cxb 3590 with three 5.8"-36" heat sinks. Do I need to ground the heat sinks ? And do I just ground them to the extension cord. Thanks !

Hello Rollitup,
so i'm convinced LEDS are the hottest thing since sliced bread and want to get on board. I run a small microgreens business and I'm looking to convert my recent growroom into a full fledge LED Grow. I have 192 feet (58.5 meters) of shelving that needs lighting. I was initially going to use 4 foot fluorescent 2 lamp fixtures.

Each shelf is 8' foot long, 18" inches wide and 14" inches tall. Each unit is made of 4 such shelves.

I've searched and only found a few posts on using LEDs for microgreens but didnt find anything conclusive, that or im slow and missed some pertinent information.

LED strip lighting seem ideal for my application. COBS would be great but my hight restriction prevents me from using them. I was thinking of replicating the Philips Green Power LED production model strip lights.

What would be the best bang for the buck cost/lumen out put? I don't need super high components, but somewhere around 80% of the best.

I'm from Canada so, Canadian distributors would be a boon considering how shiet the Canadian dollar is to the American.

Thanks!
