CXA 2530 vs CXB 2540 questions.

So I know some about cob chips to get me by but not so much about each one specifically.

Basically here's my dilemma.

-Cob Led light that costs 300
-4x cree cobs ( cxa2530)
-extra blurple 10 watt chips driven at 5 watts
-Draws 450 watts from the wall
-90degree lenses

-Cob Led light that costs 600
-4x cree cobs (cxb2540)
-extra blurple 10 watt.chips driven at 5 watts
-draws 450 watts from the wal
-90 degree lenses

The two lights are almost identical accept the cobs.

I know anything cxb is more efficient and better than cxa but I don't know by exactly how much.

Both have the same light emitting surface but both are driven differently.

I dont really have the money to buy the 600 dollar light.


Will the cxa2530 be sufficient to still grow an amazing plant even tho it's one if the first crees produced?

I am growing for as high a yield as I can get on a budget.

Please dont suggest hps Ill have a hps going in another tent and wanted to do a side by side comparison.

Thanks
Mike

Pretty sure you can find alot of better Cob's out there now, what price are those ones your looking at? And have you looked at led strips? They seem to be really good option as well.

I know for a fact that u can pick up much better Cob's for around 10 buck's each, or some led strips that would give better coverage for around 15 Buck's each depending on what u get.

You can just google the cxb and cxa### data sheets and look at the lm/w.

But I agree with the guy above, there are far better cobs than that and to be honest both those setups sound like they are overpriced.

Is someone selling these or are you building them?

Arrow. Com is very good for international shipping, usually very cheap or free shipping. Along with being very competitive with prices on drivers/LEDs/heatsinks u name it

Sounds to me like one of those companies that chucks in a few of the cheapest cree cobs they can so they can put cree cob in the title and sell em for more.

I was trying to keep the companies names out of them to prevent any biased opinions

Ones optic and ones philizon.

Ones American made one chinese.

Both have research and development teams. Philzon has many options of lights from blurple, to cobs, to quantum with Samsung chips.

As do optic

Optic. Claims 2lbs per optic six. I've seen it in grow journals. Uses epistar/bridgelux chips and cxb 2540
1100.00 canadian

Philizon 3000 watt (they do list it as being 650 watt power draw from wall.
Almost identical to the optic. Uses epistar double chip 10 watt led driven at half power.
Cxa2530 cobs (which customer service happily provided)
550.00 canadian

i cant post any links because I'm a new user.



Eventually I'll like to make a quantum board that will fill a 4x4 area or buy a prebuilt one.

But they are expensive.

I mean the optic 8 is 1600 bucks but buddy pulled 2.4 lbs dry off of one grow and 2lbs off the optic 6. So I know they work

I'm just trying to decide if that philizon that's built NEARLY the same all the a little outdated might perform as well

Every shit light on the market says using epistar/bridgelux and like I say the cree's are there for sales tactic.

Never buy any light that says 3000w and isn't 3000w at the wall. Its a sign of something to avoid.

The philizon is a pile of shit and well overpriced.
The optic is alright but still expensive. For that price there are better options.

On a budget the hortibloom bars are pretty good and are what they are supposed to be.
And more efficient than those lights with a better light spread.

Other than that and the HLG semi diy option I would suggest building one yourself for less money.
The hortibloom are currently hard to beat on value.

I can show you some live grow pics with two of my tents if you like later.
One is hlg quantum boards and the other is similar to the hortibloom bars, though mine I built myself and are made from citizen 1825 cobs rather than 1212s
But it can give you an idea of what a bare cob or a QB can do.
Just give me a shout when your back home.

Ok Corey thanks I really appreciate it.
I bought the philizon. It hasnt arrived yet and can return for a full refund.

I starting researching more.in depth about led.chips after.the fact and was concerned about the outdated cobs they use..its why I'm here.
It kept me up all.last night wondering how bad a choice i made.

My budget is around 500-700 Canadian I guess..any more.and my wifes going to kick the shit out of me..I'm on breakup and shouldnt be spending money.

K buddy on my way home.

-So as of right now I sprouted 4x chronic widow (white widow x the chronic) from Ilovegrowingmarijuana one of their biggest yielders
-they only.got their first set of true leaves. They still babies
-growing with organic hotsoil from stepwell soil
- 7 gallon fabric pots from vivosun (final grow pot(
-6.6 ph water after going through RO



-I've got them in a 3x3 tent
-4" fan and filter )
-environmental temp.and humidty controller..dont need.the humidty.side as there.is none in.alberta
-600watt hps and mh light and open ended fixture.
-got a scrog not and was gonna fim.

My.plan was start small........

I do have an 8x8x7 tent from quictent brand new............
Was thinking of throwing the 600 watt hps in one corner and whatever.light we come.up with for the other corner basically using a 4x8 section of the tent. To grow 2 to 4 plants. When I have some more money later will buy 2 more lights to.fill out the tent

That´s kind of crazy if you think about the specs of the cxa2530/2540 .
First of all the cxa2530 have a max of 65 watt @ full power.
So 4 of them is 260 Watts so there must be go 190 Watts through the blurple lights and all driven at full power.

The Cxa2540 have a max of 85 Watts in full load so thats 340 Watts for 4 of them.
Well, it looks to me thats the extra or call it a spare to use only 110 Watts of Blurple lights on them and sell them for double the price if they both draw 450 Watts @ the wall.
Check the cree cxa 2530´s on aliexpress, 4 of them cost you around 25 Euros and the 2540 around 35 Euro for 4 of them.
yes they work great on growing buds but for that money you have far more better options for that money.

Agreed thanks for the reply.

I am looking at these lumagrow 4 cob leds.

So the straight cob led like the citizen 12 or 18 puts out pure white light with a cri of 80-90 correct? Now the uv and ir chips they put on blurple help the plant produce resins to protect itself or so I've read.......
Will these citizens give out that ir or uv light to produce more resins? Or are the pure white full spectrums cob just so good it doesnt matter about having those ur and ir addedn to the equation?

As far as i read the Luma leds are a great value for that price and yes they will grow excellent buds just like other good Leds will do.
Don´t wurry for now to add extra 660 or 730 NM , just try first the led growing it self and use the time of the first grow to learn more on adding extra lightspectrums,
you will grow quality in that forst grow if you know how to grow that´s 4 sure with these kind of quality leds.

As speaking about protection with this high intense lights , some ´ CalMag´ or Epsom salt as extra in the nutrients you normal give for your plants is a good thing to study.
Search that terms on this forum and you will learn some great stuff .
