Custom led light diy

[justsmokedope]

Basicly ive come up with a rough design based upon a DS XML 650 but added a few extras and different leds

3W ULTRAVIOLET UV LED (380-390NM EPILED) x16
FAR RED / IR LED (740-745NM EPILED) - 800MA x16
3W ROYAL BLUE LED (440NM EPILED) x32
3W BRIGHT BLUE LED (EPILED 460NM) x16
3W FULL SPECTRUM PAR LED (BRIDGELUX 380-840NM) x16
AMBER POWER LED (EPILED 595-610NM) - 800MA x16
Deep Red LED (640-660nm EPILED) - 800mA x48
Bright Red LED (630nm EPILED) - 800mA x 96

Cree xm l2 10w 35 degree x25

i have a few questions that need clearing up before i can settle on a design.

one question is this too much red and also are deep reds now good enough and efficient enough to use less of the bright reds or is it still better to use more bright reds?

secondly how much is a good amount of uv and a good amount of IR will having too much stunt or halm growth?

also if i add all this to getther its 256 x3w + 25x 10w = 1018w in terms of led does 3w mean 3w?
also what driver would i need to run this would i need like 9 or 10 28v ones ?

i set out to kind of copy a http://store.advancedledlights.com/3w-led-grow-lights/new-diamond-series-xml-10w-cree-xml/ ds xml 650

but it seem to be turning into a monster
for example if i reduced the number of full spectrum and ir and uv leds would this make much diffence in grow etc

its confusing cus the one that i was looking at copying has exactly the same number leds but loos like its only 650w average draw

DS XML 650

im prob going to put dimmers on this too

actualy concidering theres is like £1500 this will be a hell of a lot cheaper like £450- £500 built

any help would be appreciated

seems like your missing 430nm in that mix. 3 watt leds should be driven at 600-700ma or about 2 watts per diode. in order to get a reasonable live expectancy out of then, the leds you list are not that efficient. only about 29% at 650ma.perhaps you should spend a little time here looking at what others are doing and do a little more research before investing money in this project

thanks this is very muck a work in progress the one i was looking at trying to copy uses cree and bridge lux leds are there some better makes i could look at that are more efficent

 

[BobCajun]

I've read that amber LEDs are very inefficient. 595-610 is not a very active band anyway. Also wouldn't bother with the UV-A, since it's not of much use really. UV-B is what supposedly enhances THC content. UV-A is just blacklight. LEDs can't put out enough intensity in UV anyway. That's why there are no UV reptile lights, in addition to the high cost for UV-B LEDs. Blacklight CFLs would likely be as much good as UV-A LEDs and cost less. I just don't see much point in the UVs really. It sounds good in grow light sales pitches but in reality is probably useless and not worth the hazard to eyes and skin. I expect you'd be better off using the money to buy more reds, blues and whites.

The far red ones may be useful, if you don't mind the stretching. I don't know if they actually increase yield or not though. Haven't seen any experiments proving that yet. Personally I would just use red, blue and white, all very efficient and photosynthetically active.

if your on a budget you may want to consider these http://www.ebay.com/itm/371119793162?_trksid=p2055119.m1438.l2649&var=640279405312&ssPageName=STRK:MEBIDX:IT at 600ma they should give you good efficiency and mixed with those bridgelux full spectrum leds and a few 430nm leds should give you a pretty good spectrum. UV is only useful at the end of flowering. just a suggestion for you to consider

these cree leds seem more efficient but reds still are not so efficient but seems like its a thing with the red spectrum i might fill in the gaps were the ?????? are with those a few of the other ones and might just use a few of the full spectrum uv leds for safe measure and yes i was thinking uv was a bit of a waist of watts

that was kind of why i was gona use CREE XM-L2 10w Warm White LED 2,600-3,700K color temperature ( graph looks closer to photosythis chart) will have to compare

 

[Growmau5]

If it were me, and I was dead set on building this kind of light, I would go
40% xml2 3000k @1750ma
40% xml2 4000k @1750ma
20% Osram , Phillips deep red, or Cree 660nm and call it a day. @700ma

I've had some nice results & experience with these diodes at these drive currents.

That's just my 2c. Take it or leave it. But over complicating a build to achieve " full spectrum" is a fools errand.

Thanks for you input ! i actualy watch a few of your youtube vids and that was one of the reasons i decided to have a go a designing my own light as i keep coming across led lights that claim to be the best but arnt realy and cant tell what leds are actualy in them also for say a quater of the pricetag of a suposed decent light i could build somthing simular after a little reasurch..
i know this is a bit big at the moment . i tend to over build stuff llike hell then pull it back a little and settle on a design. prob wont do a full spec i will mainly use leds in the red 660nm regon and 450-465nm 465-485nm wavelength . and with xml2 white light this should give me penatration and a better spectrum spred any way.

i know you guys all like cobs are these better to use but i thought they are just 1w leds on a grid but i supose 1 w leds are more efficiant than 3w leds ?

I bought the DS XML 150 and it is brand new still in the box. I will sell it to you for $400, $150 less than the current price. PM me if you are interested. Will save you time and money. I built a DIY instead. peace

chears but im pritty set on a diy build too it just a matter of what i build haha

A couple years back when I first started visiting RIU talk of magnesium deficiency was common. Since more people are using white led from whatever source the magnesium comments have all but disappeared. It would be a good idea to invest a nice portion of those diodes in full spectrum light like Growmau5 suggests.

Note from a customer: I ran it (white cob lamp) side by side with my (12 band LED grow light) and for whatever reason the the plants under the (cob) stayed healthy always.. I'm not sure why but I swapped the plants about 3 weeks into flower, the plants that were under the (12 band) the first 3 weeks started having cal deficiencies while the (cob) plants were very healthy. After the swap the ones under the (12 band) started to have deficiencies ?? Is it the "blurple" that causes it?

 

[justsmokedope]

yes i took that on board so tweeked my design:

final led light

1x Total Spectrum Violet UV LED- Two chips with 400-410nm wavelength and two chips with 410-420nm wavelength for full coverage!
2x Ultramarine Royal Blue LED (440-445nm)
1x CREE XT-E Royal Blue LED 450-465nm wavelength
1x CREE XP-E Blue 3W LED 465-485nm wavelength

2x CREE XM-L2 Neutral White LED 3,700-5,000K color temperature
2x CREE XM-L2 Warm White LED 2,600-3,700K color temperature

2x 3W FULL SPECTRUM PAR LED (BRIDGELUX 380-840NM)
1x CREE XP-E Amber LED 585-595nm wavelength
2x CREE XP-E Red-Orange LED 610-620nm wavelength
4x CREE XP-E Red LED 620-630nm wavelength
1x EPILED Deep Red LED (640-660nm EPILED) - 800mA
8x CREE XP-E Photo Red(660nm)LED 650-670nm wavelength

1 x CREE XP-E Far Red LED 720-740nm wavelength

also doing this smaller light first besides i figure i can always tweek stuff or use in my next light

 

[justsmokedope]

ive actuly decided to do two lights now one cob and one individual leds
mainly cus the cobs were realy cheep and you lot on here got me thinking about it haha

so im going to do a kind of comparison 1 is 99% cree the other cob one is bridgelux and epiled all parts ordered now to wait

I know you already ordered your stuff but keep forward voltage in mind when selecting your drive currents.
eg.

your blues 380-480 typically have a Fv of 3.5v @ 700ma = 2.45 watts per diode
your reds 600-700 typically have a Fv of 2.3v @ 700ma = 1.61 watts per diode (but they can take up to 1000ma)

So choose your currents wisely so you don't end up with a really blue leaning light. And good luck with your build.

im going to get some of those nice glass lenses you like on one og you vids from alibara and i willl put a few different leds under each of the 100mm lenes how many do you think i can get under each 4/5 or more ?

basicly thoought the cobs were cheap enough and so i thought i would build two lights one with cobs mainly and the other indervidual leds

im prob going to do a kind of spider style light too like you seem to like too im trying to find long aluminum heat sinks too but can only find short ones any ideas were online i can find them ? thanks

 

[justsmokedope]

ok so found some drivers that will run this i think ut have to figure out now how to wire into one plug hummmm
in the [xxxxma] is what im thinking at running the leds at max at as the drivers are all dimable i could always dimm certain sets etc .

as you can see ive picked some driver s that will prob do the job of running these light how ever i would be running most led above %50 most would be about %75 i supose though i can just dim then to get more life ?
