REALSTYLES DIY CXB3590 TUTORIAL

[luvdemshrooms]

indeed i have and everything checks out.
i found out that one of them is cracked and that's why they weren't functioning. i have been extra cautious handling them, i think it's a production failure.http://imgur.com/a/VYlfh

That's what they look like when you overheat them.

I have a couple here exactly like it.

overheated indeed

 

[REALSTYLES]

Well guys it's been a minute. I've been busy making lights and growing

Great to see ya back posting RS, got anything new up your sleeves???

Yeah gonna be making Aero cloners.

Cool, post em up!

What lens are you taking that photo with?

All 90 degree Lenses on 3000k 3500k 4000k 5000k, 8 in total, Lights are about 15 - 20 inches above canopy.

Peace.

I have one question for you sirs.

Would I be able to run 2x cxb3590 (36Veach) on this driver ELG-150-C2100?

Wattage: 150watts
Rated current: 2100mA
Voltage: 72V

 

[welight]

you would be on the absolute limit of the supply, would not recommend, you really want around max 85V output to be safe
Cheers

actually its a perfect combo

I was more concerned about the 2100mA since when connected in series both COBs work on 2100mA they do not share the current.
Thank you for the feedback guys I will probably use this driver.

Should be fine, make sure not to use a thick layer of thermal paste when mounting the COB to the heatsink.

Running LEDS in series is not a problems, but in a parallel (even if they are the same type LEDS) is not recommended (as each individual COB might have a different internal resistance, even if they are the same model).

Peace and happy growing.

I use thermal pads lol. I've been super busy and testing some new lights. I'll post some pics soon.

Hey I've been reading massive amounts about cobs over the last 2 weeks and I've decided I'm going to upgrade and build my own panels. It will be a massive setup 72 cobs for flowering tent one cxb3590 3500k for every sqft and in my veg area 1 cxb3590 5000k every square foot. I plan on wiring some seperate 3w leds in between my cobs for UV and broader spectrum on a 700a driver.

The issue I'm sat with, which I can't resolve on my own other than wasting money on testing several drivers before I by is that I run with a low height. I keep my plants under 2ft tall so every cm counts.

Ideally I want 2ft of penetration whilst also being able to keep the lights up to 6 inch from the canopy.

I am thinking about using lenses but if I do 120 degree lenses would be best as 1sqft wouldn't be covered at 6 inch with a 90 degree lens.

I'm undecided as to wether running 1050a 36v at 37w or 1400a at 50w per cob.

I run with critical mass and I could use your advise on wether bleaching would occur at 6 inch for 1400a and what would be best to use.

Cheers

I could possibly do 12 inch from canopy in flower But my veg room would definitely need 6 inch from canopy.

My other question is I would be building fixtures 47 inch long 6.5 inches wider

Each fixture will contain 3 of these heat sinks using iron or steel angles to keep them in one piece.

I'll have a total of 6 of these fixtures in the flower room. With 12 -18 drivers. Is there anyway I can solder extra wire to each of the drivers potentiometer cable and wire them all to the same potentiometer so I don't have to dim every single one?

Also could anyone explain to me what the difference between bins are and what the Cri and 80RA mean?

I've spoken to kingbrite to get my leds but I want to buy the best available leds and he said he only has 90ra in stock At the moment instead of 80RA what is that?

Cheers

Going of memory, But bins are different graded COBS (might have better colour output) as opposed to other binned COBS (CXA would be better than a CXB COB)

http://www.fullspectrumsolutions.com/cri_explained.htm

Give the above a read about CRI (something to do with color).

 

[Steve2324]

So I'd be best off buying cxa instead of the cxb3590s?

 

[Steve2324]

I need to start all my research again haha. I had no idea there was a better cob than the cxb3590 at the moment

 

[Koondense]

Steve,
in simple terms.

Cri is "color rendering index", higher values mean more "white" light but less total output*.
RA is same value but for some reason they lable it as Ra instead of cri.

Don't go for CXA but take some CXB3070 instead. Or even better get a Vero29 version 7.

Cri(Ra) 80 is good for growing and is a great compromise of "white resemblance" and total photon output. I wouldn't go with Ra90 for plants except if I were a pure white light freak. Which I'm not

Another suggestion: Google is a great tool to get the infos you need without waiting for people's replies.

Cheers
