Need help on led cobs and driver?

I have purchased a couple cbx 3590 heat sinks...i have found a couple meanwell drivers ...i need help choosing which driver is best and which cob to go with the driver have been on digitech but theres so many choose from im all confused. ..here are the drivers a meanwell Hgb 60-1050 or hgb 60-1400? And which cob to go with it? Lens or no lens ...shade? Aand want aa full spectrum cob aaany help and direct links wud be great

50 volt cob x 1050= 54 watts.... 36 volt cob x 1400 = 50 watts...

Thaanks alreaady sourced drivers ...but ya info very useful say if i go for the fifty volt aany aadvise which cob have looked and there aare so many aand im a noob to led

Citizen 048 1812 is what I have.. 1812 is 50 volts.... 1212 is 36 volts.. Luminus cxm 22 is 50 volts and more efficient than 3590s...

Aare these the right spectrum and would the go with aa hgb-60-1050 driver? https://uk.rs-online.com/web/p/cob-leds/8847383/

You cann only use a 36v cob as the Vf is 37-53 for both.

always good to know some basic information - before answering questions

to chose a driver and chips it`s helpfull to know:

- size of your grow room
- how many plants
- veg or bloom (or both)
- tall plants or i.e. scrog / sog

the drivers you mentioned are not very efficient (90%)
if you want to drive more than on chip -
it can be cheaper and more efficient(94%) to chose a bigger driver
and drive several chips in series or parallel.

Thanks for the advise ive recently got a quote off king brite for aa 6 cob set up,dunno if this is enough for a 1.2mx1.2m scrog have a small 300w vipraspectra too .... im thinking ov goin with the vero 29 3500k but i might ask him chuck aanother 3 in maybe 4000k or 5000k would like sum advise from u cob growers im new to led and am ready to taake the plunge here is the prices ive received .....
6pcs-CXB3590 3500k : $29usd/pcs

6sets - glass lens KB-HB100-80 for CXB3590 : $5usd/pcs



6pcs-Vero29 Gen7 3500K 80CRI 38V : $22.5usd/pcs

6sets - glass lens KB-HB78-90 for Vero29 : $3.8usd/pcs



4pcs-133mm(for 50-60W) heatsink : $10usd/pcs.

6pcs-thermal tape : $0.3usd/pcs
5pcs - Wago 222-412 :$0.4usd/pcs

1pcs - MW HLG-320H-C1400B : $78usd/pcs

1pcs - TOCOS (soldered) 100K linear potentiometer : $7usd/pcs

if the heatsinks are only drilled for cxb3590 no other cob fits that

are they perhaps drilled for 35mm holders as well?

the luminus cxm22 i have for $19 are brighter than both of the chips you list from kingbrite

i don`t like lenses so much - they always decrease light ~ 5-10%
and increase temps of your chips - LES(light emitting surface) normally is cooled by air convection. Specially for a scrog grow you may find them useless - because without lenses you
can get closer to canopy

to cover 1,2x1,2m i would go with 9 chips(up to ~40W each) mounted on a 90 x 90cm frame.

I-0,9m-I
0 - 0 - 0
0 - 0 - 0
0 - 0 - 0

2 x hlg320 wired in parallel to reach ~560W / 16sqf


driving them with 2 parallel drivers MW HLG-320H-C2800B --- (3 in series 3 parallel) -
your cxbs will run @ high efficient 1866mA (make shure that each series have the ~same Vf)

How do you wire two drivers in parallel to run a 3s3p circuit?
You do not recommend an electro noob to wire two high voltage drivers together to one power source with 5,6Amps or do you..?
You should keep such advice for yourself, mate!

SORRY man - you are right - and I am stupid
I followed a thread few days ago:

and read some info about here:

unfortunately i forgot to read this also:

https://www.power-supplies-australia.com.au/blog/can-you-parallel-2-mean-well-led-drivers

so @roosterfish - please notice

Can i have vero 29(d) and the cree 3590 on a mw hlg 320 H-c1400b driver?am i right that the ds are more current friendly? Because i thinkin ov havin a mix....and how many cobs will this driver run?

You can mix different COB's in a series circuit, only have a look at the drivers voltage range. HLG-320H-C1400 should be within 114 and 228vdc. That's enough for up to six 36v COB's...

Right so im thinking ov buying 8 (just for now ) im sure ill be adding. ...do i go with 4 cree 3500k 3590s and 4 vero 29 3500k ....on separate. HLG-320H-C1400 drivers so i can add later or wud anyone recommend a mix sum softer 3000k etc with 3500k? Dunno bein new to cobs etc im relying on sum gud advise ...i have looked into the citizen cobs too and u they seem to be quality too for the price any bang on advise wud be good i need make aa decision so my attention caan be switched else where aalot of reading gettin overload latley

If I were you, I would take 8 Luminus CXM22, all 3500°K, but in CRI90.
The CXM22 is currently the most efficient COB and you can get it from cobkits for less than 20 bucks per COB. But you need the HLG-320H-C1050B to drive each COB at 50w and be able to add two more COBs later.

I you can do me a 8 light set up cheaper than kingbrite well id defo consider coming to u for my lights? I am in the uk?

competing with kingbrite when shipping internationally is tough. prices are all on my site so take a look

They have even said they will put a lower aamount so i dont have pay as much on shipping

With 8 pin fin heatsinks we are already talking about 50-100 $ US international shipping. I bought a couple of times from Jerry, but without a heat sink, and each time it was $ 40 shipping with dhl. Incl. it would be 100$ at least with dhl..
