Diy LED gurus NEED help

[bleedfire]

Hey guys Im thinking of making my own Diy Led light

Im going to be using 5x10W High power LEDS 20000k they are 80Lms Per watt in total 4000LM with 90Degree lens the also have Royal Blue

I'm going to be using this with my tank it is 48"L 18w" 30"H

Here are the tools im going to be using
5x Heatsink 10W
5x 10W Led Dimmable Driver
5x 10W Led Lens 90Degree optics
total cost 180$

Im going to apply this in a 4' by 1' aluminium sheet

now my question is wiring them

Im really know at this wiring and soldering and all that
but could i make it work with this type of wiring

sorry if its really bad explanation

[Skeptic_07]

seems like you have the right idea but without knowing the specs of the driver and LEDs you're using its tough to tell. you usually don't use one LED per driver but I have no idea about those LEDs you're using or the drivers you chose so its tough to tell. Those lenses are probably a waste of $ because they look more like diffusers... unless its just a really bad photo. anyways, if you could post links to the datasheets for all the stuff you picked it would be a big help.

So what you think of this LEDS they seem legit to me I ordered one just in case first
to set 1 up it cost about 35$ higher quantaties better price though

[Skeptic_07]

i think that would work then. i'd advise you to buy terminal strips for your connections like this

[bleedfire]

Thanks i got it all in tact should i just use all 5 for 1 socket because its only 50Watts

[Skeptic_07]

yeah you can put them all on one socket. i managed to find their ebay store after posting. let us know how they work.

[bleedfire]

I will forsure they seem quite bright should come in 2 days

[TheFishMan65]

I am not sure this a bargain.
$35 for 800 lumens what is the quantity discount
$8 x 4 = $32 XP-G at 700ma 973 lumens (9.1 watts or 107 lumens/watt)

You can get XP-G under $5.

You can get XP-G under $5.

so for 4 Cree Led its 32$ they are 3w each? or 9?

if 3 i would need 16 of them so there goes 96$
Driver for lighting 16 Crees they are 1.50$ per driver so 16x1.5 24$
thats 120$
Heatsink for a 1sq are 40$ x 2 =80$

so 200$? all together yes?

[bleedfire]

as for what im building

5x10W 800LM led 20000k or royal blue is 50$
driver is 55$
heatsinks with fan cost 45$
and lens are 30$

orrr I could get it premaid this are 35$ a piece
40$x5=200$

and they look like this

I thought this was one LED only and then add driver and everything else.

How much is one LED?
How much is one one driver?

[TheFishMan65]

One 3 watt cree gives about 250 Lumen. It costs $8 or less. Say $3 per driver. that makes $44 for 973 lumens.

So what did it take to get the 800 Lumen? One $35 LED and a $55 driver? I am really confused.

What angle lenses? I can find lots of 40/60 for $1.25 or less.

[bleedfire]

well those flood looking lights cost 40$ they are 10W 800LM plug and play 140 optics

the diy
is 10$ for 10W led 20000k
10$ for 10W Driver
7$ for heat sink/with fan
and 3$ for the lens the lens is 90 degree optics

it cost 150$ to make five 10W 90 Degree optics 4000Lm fixture Lol

but to order it already made is 200$ for five fixture

[TheFishMan65]

I would think for $10 each it was worth for the case. My only issue would be the optics, IMHO 140 is kind of wide. You will also pay 20-25% more in electricity (I think that is the main advantage of the Crees).

Any idea what the spectrum is like? That would be my next question?

Just so you can compare in quantity you can get the the Crees down to around $6.50-$7.00. Or $26-$28 plus lenses ($.075) and heat sink (use cheap home depot U channel).

the highest they go is 20000k and that is the one in the picture I've never seen the royal Blue

[bleedfire]

Bump

any one else think this is a decent lighting to grow corals?

Also if a i have a 50W driver would that be able to power all five 10W ledS?

http://i153.photobucket.com/albums/s...eraRoll005.jpgI have done this with six 20K and six Royal blue 10w leds. this setup is currently on a 55 gallon tank and has been running for 8 months. If you need more information let me know.

[Airsick]

Pretty sure those LED arrays are not Bridgelux so their efficiency is probably lower than what is stated. I have used Bridgelux for other projects and they are a pretty good LED but do generate quite a bit more waste heat than CREE so you will need to take that into account when planning for heatsinks.

how are the corals most importantly

Do you have any more specs on your LED system? I'm planning on building a set from ReefLED for my 120G and I'm trying to become more educated..

[robertjaguar]

LPS corals are fine. Branching hammer went from 5 to 10 heads in 8 months. Frogspawn opens nicley but no growth as of yet, however, it is posistioned lower in the tank. Galaxia is showing growth. Birdsnest is growing but has die off on the base. Montapora is white edged and growing. Pagoda Scroll is comming out daily. Added a Stag Horn 3 months ago and is showing some growth. Mushroom ployps are happy. and ofcourse Xenia is growing like a weed. LOL! Currently setting up a BC29 with 12 ten Watt LED's. Im going with the 10K LEDS on this project to see if there is more growth. I can post more pics if needed.

Specs on 55 Gallon:
Oddssey Hood retro fitted with 12 ten watt leds. Spaced 4" inches apart.
Using constant current source schematic for high power LED's from the instructables website.
Two 12v 10A switching power supplies (one for 20K LED's and one for Royal Blue LEDs)
Two 12V 8A LED dimmers
LED's are mounted on an 1/8th inch aluminum bar 4"x40" roughly.
6 video cooler fans with heatsinks (do not use, they become noisy after 2 months)

I will not use the combination of 20K and Royal Blue again because the tank is too blue and not sure if Im getting the best coral growth.

This is a good question.

Spectrum and color temp are not the same thing.

Corals like the 420 nm wave length. That comes from actinic normally, or RB LEDs. I am betting you do not have enough water penetration or simply not enough light.
What lighting did you have before? The growth you are describing is weak compared to the cree LED set ups.


Also, those LED's do not have constant color, I would never put them over my tank, I use a couple of those premade ones linked above for photography, and once they heat up the color from them is inconsistent, you can't see it with your eye, but the camera doesn't lie, It's not huge, but it is there.

You sed you had one before what did you use it for and how was it?

their wavelenght is 460

[TheFishMan65]

Wavelength is also not spectrum. It gives the peak, but not the overall.
