I saw there was a lot of new stuff out there. The cxa is still supposed to be pretty good as far as I understand it. I got the 3000k I just couldn't determine how much better off I'd be with a cxb
I wonder about Spectrum quality though?Cxb produces 30% more light.
So if cxb is way better than a cxa is what you're telling me
Cxb produces 30% more light.
How many watts at the wall should I expect to be pulling running 2 cxa 3070?
I think you are correct but I would definitely check with someone else I'm not that good.So yeah guys
Bit of a noob question I'm afraid
I am currently in the process of building some more rails in Vero 29 to go with the Cree and something got me kinda turned around
With the Pico Ez-mate connectors for the chips, you have a red (+) and a black (-) pigtail. So for series wiring in my mind you would have the + from the driver into the red pigtail of the first cob, then the black pigtail would run to a wago or whatever and then have the red pigtail of the second COB connected to that same wago and so on and so on till you get back to the driver...
I know that all sounds correct but when I was looking at it, the red going to black wires at the wago connection kinda threw me like I was doing something wrong. Thought maybe I should just ask instead of potentially blowing the string or other expensive shenanigans
Have I got it right fellas?
Your help is appreciated
Cheers

That's exactly what I was going to say Since you cannot return it and get a different one. Just move your light up to an acceptable range and supplement with your CFLs save your money for a better light on your next grow.Ok thanks
Oh crap wrong post sorryOk thanks
if it was me i would use 9 cobs @ 1400ma for that 3 x 3.save on cobs,heatsinks,misc parts.you can use hlg-240-1400ma to power 5 x cobs and hlg 185-1400ma to power the other 4 cobs. or just get 2 of the 240-1400 drivers and run 10 cobs in a slightly dif config. you will still have good efficiency and more power for taller plants.but def ask them for db bin cree.Hi guys!
So got some questions I hope you can help me with. Today I got 690w of hps in a 3x3 tent but I want to switch to led.
I've been talking to Vicky from kingbrite and got this shoppinglist, what do you think?
16pcs cree cxb3590 CD bin 3500k 36v: 31usd/pcs;
16pcs ideal holder 50-2303CR: 2.8usd/pcs;
16pcs ideal 50-2300AN: 1.0usd/pcs;
16pcs Reflector KB-D82-90RF: 0.8usd/pcs;
16pcs pre-drilled heatsink Φ133*H70mm(for 50-65W): 10.0usd/pcs
2pcs meanwell HLG-185H-C700B: 40.5usd/pcs;
2pcs TOCOS (soldered) 100K linear potentiometer: 7.25usd/pcs;
I'm planning on running 8 cobs on each driver so it will be 23w at each cob. What will the efficiency be and do I need something else besides wires and a frame?
Sorry for all the questions, hope you can give me some good input.

your plan is fine as well,i just like more power per cob than 23w.its easy to dim the 50w but you cant boost the 23w
