LED FAQ) Building and DIY

[jesbuds]

Getting close, waiting on some fan grills for the side vents and done with cutting. After side vents just glue/re-enforce/permanently affix things and paint to make it look purty.

I did end up wiring the fans into same socket as COBs, figure it's best to ensure fans are always on when COBs are.

 

[Dion]

Well done Dion! I thank you for your time and knowledge devoted to this thread. I have learned a lot and I'm only 9 pages deep.

Have been thinking I'd like to build a diy lamp for my 5x5 flower space. I currently have a 600w HPS in there and it needs help i think. So my needs are supplemental. Do you think 2 cxb3590 CRI90 bin BD would be enough to cover 2x3 of the area?
Would I want to push them at the current used in the data sheet or is that being coservitive? Too much?
Would this driver be good to use with 2 cxb3590? I like the one driver per option but can't seem to find a good one.
Also a recommendation on good heatsink to keep em cool would be great.
Sorry if these questions have been asked, as i still have a lot to read.
Appreciate any input.

Peace, Roast.

hey

that driver is unusual as in the cool kids dont use it but its one ive actually been thinking about lately mostly because of cost

do you need dimming? for supplementing a 600w hps i think not so better just get a cheaper driver

if you like 1 per cob you can look at the low cost meanwells or

http://www.mouser.at/ProductDetail/...8HCqAgoHdLOWRZPjdE7ov3Y2lc4sw2L2GJSQSYiWvbw==

this will driver 2 of those chips at 75w eACH

OR

http://www.tme.eu/en/details/lpc-100-2100/led-power-supplies/mean-well/ single cob

actually lots of options check out the pct and see what current you wanna drive those at

I think 2 cxb3590s driven hard is a good way to step into this

good value for sure

u will use the alpine 64 plus to cool these

get the meanwell APV to drive the fans its cheap and good

so

2 cobs is not really enough to cover that space but if ur sure you just wanna spend for 2 you can sacrifice efficency and drive those harder for now-switch out the driver for a softer one later with upgrade

in that case i suggest you run each cob at 100w


if u tell what continent ur on i can help better

 

[krood]

so im running into problems powering my alpine eleven plus fans. each fan is rated .25ma on the back, i specifically bought a dc plug rated at 2.5 amps to power my eight fans. when i wired them all together(parallel, using the red and black wires only) nothing happened when i plugged them into the wall. so i went from there to another wall, nothing. switched the wires around, only wired up one fan, i even cut the end off of an electric razor charger and tried that, still nothing. what am i doing wrong? also, i got a multimeter, and tested the current coming out of the open wires on the original dc converter, 12v. i just dont know.....

 

[krood]

I also took another alpine 11 fan that had not previously been wired and wired it directly to the walwart, to make sure that i did not wire all of the fans backwards, frying them, and that fan would not work either. So im pretty stumped now

well I was gonna remind you that the alpine fans burn out if wired backwards

how many volts is the wallwart?

does it work on anything else?

i think the power supply is fucked dude

 

[Koondense]

Re-check the polarity, + and - must be set the right way.

 

[Buddah Watcha]

if you wire the alpine's wrong its gg.. just get new ones. ive done that! you might be able to order just the fan, instead of the fan and the heat sink, for a bit cheaper! sorry for ur loss !

Thanks Dion! I'm in the USA.

I like this driver for each cob. Is it too much?
This is the heatsink i was thinking.
Can't seem to find TIM pads. The search continues.
I want to start with 2 cobs. Each one its own driver. More flexibility.
Can always add more later.
Always appreciate your input.

Peace, Roast.

 

[Roasty McToasty]

Do I need to worry about 2-step or 3-step versions when ordering? Can you explain what this means?
Thanks again.

Peace, Roast.

the driver you linked is great BUT 180 VAC to 295 VAC input so unless you have special eletcric in the grow room its a no go for the usa- http://www.mouser.at/ProductDetail/...=sGAEpiMZZMt5PRBMPTWcaTZzwMkhyeWLC4KgEDjU2Bk=

but cheaper to look into non diming drivers
id go for anything between 1700-3000 mA
check out sager and j

the cheapes would be to get the 72v version cxb3590 and run both on
http://www.jameco.com/1/1/52106-hlg...led-power-supply-constant-current-design.html


cpu sinks very few fit this model just get the alpine arctic 64 plus

TIM use any therMal grease dont fucka round with anything else(dont use pads)

artcic has good stuff too


2 step 3 step is relly of little concern to us

google ansi white and you will see

the dif steps just fall into dif area within the K spectruM and relaly its about CRI and light teMp
dont stress

I still don't know how to quote, but to answer your question Dion, the wall wart is an adjustable model with a sliding switch that adjusts the voltage from 6-12 (I've always left it on 12) and the output says 2.5A. when I look at the wall wart, one wire is all white (I'm assuming this is positive) and the other wire has black bars on it (I'm assuming that this is negative)

and I also hooked up a separate fan that was brand new, and that one wouldn't go either (i used only the black and red wires).

another question I have is that because I can dim my cobs down, and i was wondering if i dimmed them down and left them on the alpine 11 plus heatsinks with a small fan blowing directly on it if I could run the light without frying everything. i have the meanwell model hlg 185h-c1400a. and my understanding is that if I tune them down all the way that theyll pull approx 25 watts/cob, i do not know how many heat watts the cobs would be putting out, but the cpu cooler running properly is supposed ot be rated to cool up to 100 watts of heat.

thanks for all the help guys, i really just dont know what to do at this point. im worried that im going to buy new fans and a new power converter, and they still wont work.

honestlly just get ur fans working
i asuume you dont have equipment to test the wallwort thing so:

tommorow get ur hands on a fan(the cheapest fan you can) and see if your thing will drive it

oh wait you already did that right? so pretty sure the power supply is fuct

get a new one

better get the APV from meanwell
or see if you can get the one you have replaced? or get another one

I dont even wanna answer about not using fans-seriously u invested all this cash and wanna skimp on a 10$ fan driver? no

Thanks again Dion!
Let me show you what I'm thinking. Your input is welcome. For my first build I want to keep it simple. 2 stand alone units.

List so far:

2 x cob 3590
2 x this driver
2 x arctic 64 plus
2 x Ideal chip-loks
Will that APV-12-5 power the fan at 1 each?
My goal is to make 2 individual lamps for more placement options. Like if I want to move one to veg room. Can always add on later. Please let me know if you can see something I can do better. I've only shopped mouser and digikey so idk if I'm getting the best deal.

Anywho I love the work your doing helping folks out n shit.

Peace, Roast.

 

[Ttystikk]

Dion, nice to see you here! I've been here for years, I just hid out in my hole in the vertical section, lol

Anyway, the time has come for me to do a lighting upgrade to make up for all the time that I spent running light bulbs.

One part I'm having trouble getting answers for is the inrush current issue. I'm building a large array of chips and running 5400W of Meanwell HLG-185-C700B drivers.

Adding up my amps alone, I'd be running 22.5A@240V so theoretically I could do this on a 30A breaker with plenty of headroom. So what's the catch?

 

[jikko77]

Will that APV-12-5 power the fan at 1 each?

usually pc fan take 1a and 12v (at least the old one) or something near that value. modern one can go with a 0.xxA value and 5 or 12V.
i.e. arctic 11plus uses 0,16a and 12v.
check on the sticker in the middle of the fan, they should report the spec.

i totallly get what you are trying to do-have 2 seprate beast lamps runnning at higher wattage/lower efficiency than most to use as extra photon blasters in your flower room-love it btw, led can and shoudl be adapted for everyones use

the APV-8-12 is what you want(assuming its the cheapest) it is 8w and 12 volts(apv 12 5= 12w and 5v) no point in talking about fans now so just trust me on this

running at 100w you wanna run those fans at max so 12v

so get the APV-8-12(1 for each fan) and wire both the driver and fan driver to the same ac plug that way they always both on at the same time

the driver you linked is OK BUT STILL COULD HAVE ISSUES WITH VOLTAGE

at that current the leds will consume 37ish volts(i idint read the data sheet of ur driver so dunno if it is locked at 36 or what) and for that price id go with one of these

this is only 2100mA but good price and efficiency is decent at that current
http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2221608_-1

here it is at 2800mA if u really need to run them that hard
http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2219971_-1


so my advice is to get the 1st driver and run them at 2100mA=75w
use the APV-8-12 (2 of each driver 1 for cob 1 for fan)



wherever u buy the arctic has grease get that

ALSO DONT FORGET BINNNING!!!!!

what cobs are you getting?(bin/k temp?) and also are I am giving recomendations assuming you will use the 36v versions right? the 72v versions opens up some good options for drivers


EDIT: checked the datasheet-that driver linked is maxed at 36v so will only drive ur cobs at2300ish mA anyway

 

[palmero]

@Dion Thanks for this thread
plz forgive a noob who is studying still @page one
and trying to do the math......
But thats not the prob.
As you said "looking for drivers can be a pain"

I am looking for an economic driver @500/600 mA
37/75 Volt
for one or two CXA2530-0000- 000N0HT240F

Want to do a first test build and later use it for other purpose
can get the cobs @10$ including p&p
but dont find a cheap driver.
This is just a test, dont get me wrong
Any cooling suggestions?Would love to stay passive.

Thanks a lot
Respect
PEACE

[krood]

so i spoke with newegg today, they do not sell individual fans for the arctic cpu coolers, and gave me a number to contact arctic directly that had been disconnected. i went to the arctic website and that was even less help. im going to take the cobs off, and buy a long heatsink and attach a different fan to that, i dont see it a good idea to buy another eight arctic cpu coolers for them to possibly not work.

 

[CanadianGrower]

I got a led deign that needs your approval haha, just making prints now for my idea on cooling the heatsink, but unsure.
Forgive me if I ask dumb questions haven't had much sleep and researching a lot of multiple new things right now.
I want build a simple cob light vs many small cobs light. 2 to 3 cobs, 1 blue spectrum in middle 2 red spec on sides.
my total sqftage is 1 lol any ideas for cobs on 8x8 area each. I want alot of lumens so no stretching and i got some insane air flow so heat no issue. but concerned about light burn with these bad ass cobs
more info here or if you prefer to talk on there and ill post conclusion build here
