This is going to be my BC14 upgrade. I am useing a 8.5"x5"x1" heatsink with 6-blue cree xr-e's and 6-white cree xr-e Q5 led's. For the drivers I will be useing the 2 buckpucks from ledsupply.com. More as soon as I get some more parts.

Lookin' good! Is this more or less based off the rough part list I had posted before (as in -- was that a HeatSinkUSA heat sink, and which size? :D ) Will be watching this one for sure -- I think I'm gonna order my LED parts soon as well... my biocube is itching for something fancier :D

I am interested to see how this comes out. Quick question - Is that piece stainless steel?

The Heatsink is from heatsinkusa.com, and it is 8.5"x5"x1" (aluminum). This is going to be very similiar to most other bc14 build out there. There is only so many ways to make this mod still easily fit in the stock hood without tons of cutting. Thanks for the comments and interest. I should be able to get all the wiring on the emiter board done today, so more pics to come tonight. Stephen.

The HS is aluminun not stainless, but it will fit behind the stock clear plastic splash guard. So al. oxidation should not be an issue.

Indeed -- my thoughts exactly on the pre-installed pots... just easier for the first build, esp. since its proof of concept. If all goes to plan, it would probably be a different story on the next build(s) :)

Edit: those are the same buckpucks I'm planning on -- why go for a lesser amperage when they're all the same cost? :)

Very interesting project...:) Now you got me researching LED parts to see if I can find a supplier of a 10000K LED as it looks like all the ones at most of the suppliers I've found so far are 6500K or lower.

Tue, 22nd Dec 2009, 10:47 AM
Shrimpfan: dont let kelvin ratings fool you -- the cree cool whites are a VERY white light... The spectrum is much closer, to the eye, to a 10-14k halide.. Multiple reasons for this, mostly the fact that they're universally supplemented with the royal blues, and we will be driving them MUCH lower on output than max. The cree cool whites and royal blues are absolutely what you want :)

So if I understand you correctly, you're saying that I could build an LED array using the CREEs that can effectively replace a MH light setup?

That is indeed what I'm saying... Google 'DIY LED nano' -- tons of great info over at nano-reef.com... Theres a pretty informative recent thread here as well -- search for LED and it should turn up quick :)

To be realistic about expectations, this is bleeding edge tech, so this is NOT a cost-effective way to replace halides, at least on initial investment in most cases. It is, however, for the hardcore tech geeky DIYers a wet dream :)

Well I have all the led's wired into there two groups. One for the white, and one for the blues. My buckpuck drivers showed up today. Nice and small they are 3/4"x3/4"x7/16". Now just waiting on my 24 volt power supplies.

Just curious, why did you choose 24 volt?

txg8gxp
Tue, 22nd Dec 2009, 06:12 PM
buckpucks can only handle 24v(well 30v but 24v are cheap 30v are not). On my next bigger build I may go 48v

Bill S
Tue, 22nd Dec 2009, 06:26 PM
I've got about 25 fixtures I did with buckpucks and mostly Luxeons on our boat - which is 12V. I tried a couple for my nano, but wasn't happy at all with the output.

txg8gxp
Tue, 22nd Dec 2009, 06:54 PM
The newer cree led's have much higher lumens the the older luxens, and if your comparing the luxen 1w to the cree 3w theres a major difference. The new cree xp-g in white are nice around 330 lumens. I guess we will see. I think I now have access to a par meter. So, I will have good info once everything is up and running.

Very nice wiring job -- looks great :) Are you going to use any lenses/reflectors on the emitters? My thought is in a BC8/14, the volume is so small, it probably benefits from the wider emitter range without the focus.. Thoughts?

The general rule of thumb is to space the led's 2-2.5" center to center. Say on a 55g 48" tank you could get away with a 36"-40" long light, and around 8.5 deep. Now from what I have seen from my first test, this will be plenty of light.

Who'd you get the Cree's from for 6.29 a piece? I was thinking with LEDSupply's flat rate shipping, I'd just bulk all of the parts but my heat sink and power supply through them.. but for a buck less per Cree, may be worth it to rethink :)

For big builds it would be worth getting the new cree xp-g led's. If you get 25+ from cutter.com they are around $6.70. Bin #4 right at 330 lumens. Only down side is lenses are alot more money.

From a real quick tally of the prices you gave, it seems like it would have cost $141.66 + any extra shipping or tax. Does that sound about right?

Wed, 23rd Dec 2009, 10:59 PM
Cost so far with 12 leds, 2 buckpucks, 1 power supply, and heat sink is right at $145 plus shipping. I didnt keep track of total cost. This does not include wire, tools, screws, stuff like that. I still need to buy some good cooling fans, so that will add around another $15 or less. With shipping lets call it $180 total. That sounds about right.

If you haven't found it already, I'm sure you will soon... PFO no longer exists (the manufacturers of the Solaris units..) -- and they are part of the reason that LED's aren't more widely used at the moment. Orbitec, a manufacturing and design firm, had patented a method of controlling LED's in an array, specifically for aquarium use -- and this led to them suing PFO shortly after the release of the Solaris units... There are still new LED units coming out, but they for the most part are side-stepping the issues with controller units and Orbitec, by not including the dimming/controlling capabilities within the units themselves..

AquaIllumination has some good units out -- they look impressive with the Profilux line of controllers -- wsheltonj on here has this and seems to like it.

The other DIY LED thread on MAAST is found here:

Not trying to hijack the thread, but I need to replace my MH bulbs and now this thread has me thinking about a DIY LED instead. I know NOTHING about this technology, but I am a quick learner and fairly handy at this type of work. Does anyone have any idea what I would need to light my 34G Solana, 20x20x20, to the equivalent of a 250W MH. The small bit of research I have done on the subject shows that if done correctly they will grow coral as well as any MH. Does this sound correct to ya'll?

txg8gxp
Thu, 24th Dec 2009, 01:05 PM
Yea, from my research the led's should replace the MH no problem. with a 20x20 tank I would probally run a 16x8.5 Heatsink(atleast). I would think something like 8 led x 4 led matrix(32 led). This is just a guess. With some more testing I will have a much better idea of how many leds are needed for good coverage.

I'm sorry - I just feel like I need to post this.

I LOVE LEDs. As previously noted, we've used about $1000 of components on our boat, to replace lighting.

I very nearly purchased an LED system for my 215. Got REALLY close.

Boy, I'm SO glad I didn't. While all of the stories SOUND great, and all of the tanks look nice under the lighting, I've seen very little proof that these things perform as well as MH, or even T5s. Even when you go to Aquaillumination's website, all they have is displays they've set up. Sure, stuff looks good - BUT DOES IT THRIVE AND GROW? With all of the units that have been sold or made, you would think some photos would be up by now. But, I haven't seen many. And none that would make me go... "I NEED one of those".

I'm putting together a 8 gallon SPS nano (with a 55 gallon fuge and 20 gallon sump), and while I'd love to go LEDs, there's just no way. I don't believe they will grow well.

well maybe you need more information. and please excuse me if this is remedial (i dont know how informed you or anyone else may be)

PAR (Photosynthetically active radiation) and PUR (Photosynthetically Usable Radiation)is the intensity and spectrum of light that photosynthetic organisms (plant or coral or invert) uses to maintain life. (symbiotic or solitary)

the output of LEDs can be more percisely controled and are more stable in their spectrum for a longer period of time. light waves are light wave and with enough LEDs one can surpass the performance and MH or T5 or any other fixture and exceed the efficiency by 2 to 300%

this artical is full of great information and compairs an 88 watt light array to a 250 watt MH. This artical is also using an older technology LED.
"Cree" is the current leader in "light per watt"

some of the reefers that have been using LED systems on reef tanks and recording growth are stating that a tank needs about 75-100 lumens per gallon and with an 12 led sysem Stephen (txg8gxp) should be putting out about 2400 lumens and that calculates out to 170 lumens per gallon. you will most likely need to turn the pots down!!!

that is a low ball est of 200 lumens per led. most (if from good manufacturer bin) will put out 220 lumens

When I get my lighting done, I want to do some first hand tests. I hope to get with someone local with MH lighting, and swap a frag back-n-forth a few times. This should give a good idea on growth comparisions between the two. HINT..HINT..anyone on the NE side interested?

look at the whole thread but for pics look at post #66 and #67.
he states " SPS grows in different form under LED and the intensity of Solaris I4 is possibly the minimum requirement for growing SPS. Any new LED with less intensity than Solaris I4 will be a problem."

again old technology LEDs but the growth is visible.

I'm always willing to trade rc for frags.. I love the leds, they look great... Yea why add one or two led's when I can add 12..:) As soon as I get the led's done I am leaning toward a vortech mp10... and maybe a reefkeeper lite.. Not possitive yet though.


Hey Steve, can I trade frags for RC parts?:lauging: I just got a BC14 about a week ago and I'm hooked on SW now. Nice work on the LEDs man. I was thinking of adding a couple to mine, but you just went all out. Glad to see another tinkerer I know messing with these. What's next? Parker

Thanks for all the pictures and detailed info about your successful project.

I have read up on the posts here and at reef central about LED's and understand the basics about wiring configuration with the buckpucks and power sources but do you have a link for "LED's for dummies" that I can start out on?

I am not an electrical engineer and will not pretend to be but don't think I should have to go back to school for another 8 years for this. I got lost on Cree's webpage with the specs on the LED's with the XPG's. Even if I do understand it then how does that translate to watts or lumens per gallon in our world?

Wireing is super easy. You wire the led's in series(possitive to negative) and the buckpucks are labeled very well.. If needed I can post some close up pics with a more detailed write up.. Just let me know, Stephen

Thanks Bill for the link and thanks Stephen for the info and offer for more detail. I will probably take you up on the offer in the near future. What I don’t understand is in the data sheet http://www.cree.com/products/pdf/XLampXP-G.pdf what is the group categories R2-R5? I want to make sure that the bases are easy to mount and wire. I don’t like to solder if I don’t have to.

I think what I meant to ask was what makes an LED work and how? I want to understand exactly what makes this system tick and understand all the geeky terminology when it comes to LED technology. I used to install car stereos and understand wiring in series and parallel as well. I guess I just really like to ask a lot of questions and really understand something before I try to do it. I am no electrical engineer and won’t pretend to be one but I did some research today and found the following;
1. mA is milli-amp or one thousandth of an amp (an ampere [Ah] is the measure of current through a circuit after one hour and a milli-ampere is also the measure of current but on the thousandth scale [mAh]).
a. One ampere is 6.28 X 1018 electrons passing by the point of measure in one second.
2. Volts is the measure of force/pressure behind current.
3. Watts are the typical measure of current and is equal to volts X amps or one ampere or current flowing at one volt.
4. Ohms are the measure of resistance that material has to current, if you have 1 ohm then you have 1 volt maintaining a current of 1 ampere.
5. Lumen or luminous flux is the amount of light produced observed by the human eye. It has to do with reflective surfaces and 4 X 3.14 lumens=1 candela. Lux is the amount that the light is spread out, 1 lumen into 1 square meter produces illuminance of 1 lux.

After those basics the following links give a general description of how they work; http://www.thenakedscientists.com/HTML/content/questions/question/1135/
http://www.theledlight.com/technical1.html

Basically, the diode is made up of an “N” type and “P” type semi-conductor that meet and combine to create light when current is passed through them. Red is easy to make, blue is harder but can be accomplished with chemicals in the semiconductor chip. Led’s are made of gallium-based crystals and can contain phosphorus which is added to create different colors. The color is rated in nanometers (nm) of wave length. Light is measured from an led by photometer but only on axis not as in incandescent filament bulbs which are measured in mean spherical candle power. There are single chip and 6 chip led’s and can generally handle 20 mA max at their brightest. The viewing angle of the led is determined by the shape and construction of the epoxy lens or reflectors/clusters of the led.

The following link explains bins and labeling of the leds http://www.philipslumileds.com/pdfs/AB21.pdf which was also really confusing for me at first.
:whew:

If any of the above is incorrect or missing info please correct me, I am learning as I go here.

Results can be found on SMGSLLC.com. I had there 50watt unit on my 3 gallon SPS pico and had gread results before tearing down. I had great results for a few months before tearing down the tank. The small tanks required too much maintenance and my work required me to work 12-14 hour days so the tanks had to be torn down.

Here's a pic of my system when I first set it up. The great thing about the SMGS system is that they use Rebel Tri Star LED's which can produce up to 540 lumens per star.

I'm sorry - I just feel like I need to post this.

I LOVE LEDs. As previously noted, we've used about $1000 of components on our boat, to replace lighting.

I very nearly purchased an LED system for my 215. Got REALLY close.

Boy, I'm SO glad I didn't. While all of the stories SOUND great, and all of the tanks look nice under the lighting, I've seen very little proof that these things perform as well as MH, or even T5s. Even when you go to Aquaillumination's website, all they have is displays they've set up. Sure, stuff looks good - BUT DOES IT THRIVE AND GROW? With all of the units that have been sold or made, you would think some photos would be up by now. But, I haven't seen many. And none that would make me go... "I NEED one of those".

I'm putting together a 8 gallon SPS nano (with a 55 gallon fuge and 20 gallon sump), and while I'd love to go LEDs, there's just no way. I don't believe they will grow well.

You want to buy led's mounted on stars already, the emitters need the be reflow soldiered on the star(major pain in the butt). Believe it or not I soldiered mine together with my oldest iron, a old crappy 25w weller pen iron. Even with that bad of a tool it was still a very easy job.

Took a look at the SMG website. SPS in the photos are green slimer, birdsnest and cap. Those the are the ones I give to newcomers, because they are the easiest of the SPS.

The colors in the photos are just awful. Green slimer should be electric green. The cap, mostly brown. The birdsnest, brown.

OK I saw this tank first hand tonight and HOLY STARS IT IS RETARDED AWESOME.

He basically did a live start on his tank, and did an awesome job. Justin and I were just google-eyeing that tank. It's a show stopper. The ability to change the light temp at the turn of a knob was just batty. I was having flashbacks of seeing how Ace's tank does that naturally, like when clouds pass. THE SHIMMER? OHHHHHHHHH THE SHIMMER. Immense. There were layers upon layers of different colored shimmers. The depth of color was amazing.

His SPS what appears to be a valida and a deepwater acro were doing great. I looked closely and could see new growth at the base of the smaller deepwater frag, and the small colony of valida was polyped out perfectly. On his sand he had 3 or so specie of Acans which looked nice and pillowy. His zoas were short stalked, even the zoas on the sand. Wickedly healthy for a month old reef, and from a newcomer to salt.
Stephen, I applaud you! Sorry if you found any other nose spots of mine on your nano. I hope those frags grow well.

LOL at Justin's breadboard comment. I installed some x10s the other day, and almost sent you a pic of a bnc connector, Justin. :)

The only small thing was them not having the lenses and being on a short(er) tank. There were some small blue spots on the rocks, but man, it didn't matter. It just looked like a Halide/VHO Actinic combo. Amazing........ A... Maz.... INGGGGG.

I don't know that lenses would actually help that any -- the lenses focus the output more than the bare emitter alone... it would probably be heightened, by the fact that the beam was tighter off the emitter.. but I'd agree that its a minor nitpick :)

Guys -- look into these:

http://www.amazon.com/HQRP-PowerBook-661-3048-Replacement-Mousepad/dp/B001AK5H66

(That's just the most convenient link I can find at the moment -- the eBay item number I got mine from is 250511317631 -- under $12 shipped :)

They're replacement power supplies from Apple's older model laptops (Specifically, ones that were equipped with the IBM/Apple G4 processor, as these ran on a 24v rail). Thats what I used on my Biocube, and I wouldn't think of using anything else for future projects @24v :) Looks so clean!

The actual specs are: 24 volt, 2.65a, and 65 Watts -- perfect for our applications here, and will easily drive 2 buckpucks @ 1000mA with complete (6x3w LEDs) circuits without issues :)

Considering the price, and depending on the output amperage of the driver's you're using, it should be quite adaptable on larger projects too.. Wiring in individual switching on a per-circuit basis is cake, and if you're driving things constant @750mA (which is the recommended peak for output efficiency anyhow), you could drive 3 circuits without coming near overloading the draw of the supply... I just like the cleanliness of it, and not having to build an external project box.

Obviously, on a much larger unit, there'd be benefits to creating a project box and just wiring everything external to the arrays themselves...

so can you get the same result from these led's as you would t5's. im confused

That is the big problem I have with them. I would LOVE to use them for my nano build. But I'm going 150w MH on an 8 gallon tank. :shades:

The only way to get long-term results is to give it a try though! I'm with Stephen -- I'm pretty sold on LED's. Things at work are growing like crazy, and the light itself garners a lot of attention (granted, I work in a building with approximately 1500 other extreme technology nerds...)... Plus the appearance really is fantastic. If nothing else, I'm convinced that very little (if anything) produces the actinic 'flare' that LED's do.

The reason you will not find any good long term reports on them is simple. Good led's for reef use are just now becomeing available and affordable. Just one year ago, led's were putting out alot lower numbers then todays.


Wow, 150MH on 8g. How high off the tank do you think the light will need to be?

Bill, come back by and look at my tank again, everything is still living and growing, some not so fast and others just don't stop. That 2 years and counting.

I am waiting for the upgrade kit for my light. However, just saw that Seoul now has a more powerful light then the Cree. Looks like that's going to be a never ending battle

Those new Seoul emitters are still a ways away from being a readily available bin, as I understood it... and the spectrum they produce isn't quite in the range we're looking for. Definitely going to be interesting in the next 3-5 years though, as the otherwise unknown market starts to shape and define itself...

They will be, the original AI light used Seoul's and were more powerful then the Crees that PFO was using.

Well, what a difference 2 weeks make Cree has just hit 208 lumins per watt and broke Seoul record.

Very nice job on this. I know it hasn't been very long, but can you see any evidence of growth on your corals since installing your LED system? I'm thinking about trying a build of my own for my 30gal Finnex so I really appreciate all of the info you have provided here.

Hey Steve, if and when you get a chance, temp those LEDs when they are up and running. I got an idea. Famous last words, I know, but I want to try something else just to see what works the best. Temp is my main concern.

Sorry, I no longer have a working IR temp gun.

I'm disappointed in you Steve! That's cool, I already got the lights and am going to try it any way.
