My new DIY LED set up.

As requested by Seth, I will be documenting my new build of LED build up.
My aim.
1.) Currently in my set up I have a custom center bar going horizontally across my tank in my canopy and my aim is to create two strips of LEDs that will be mounted or zip tied to the center bar.
2.) Create different light scenarios that I can control with my apex controller.
3.) Strong, energy efficient unit that can sustain SPS corals with full colors.
4.) Create full spectrum of light that will help will enhance the colors like top LED brands.
5.) Make this project as CHEAP as humanely possible and make it good at the same time.

First of all, most important thing is colors. I found these aluminum pcb circuit board that has 6 spots for every foot and my tank is 4ft and needing total of 8 ft I needed to get 48 lights.
I was considering large power LEDs then changed my mind to go with conventional 3w bulbs (easier to replace if one were to go out)
I have purchased 10 20000k Cool white, 22 Extreme Royal Blue, 10 UV (also gives that purple tint), 3 Red and 3 Green bulbs. (1 in the left, 1 in the middle and 1 on the right)

All of the LEDs come with 120 degree lenses which is fine for the color bulbs but I want intensity for the white bulbs and I ordered degree lenses for whites. 22 awg wire for the hooking them together and 3 water proof LED for 12 bulbs each. (colors) and 1 dimmable driver with dim kit for the whites so I don't kill off all of my sps.
Based on my tank height and amount of lights I'm putting in, it should be equivalent to dual 400w MH.
After I construct this, I will be housing it in aluminum casing from home depot and painting in black to match my canopy.
I just ordered it.
Total cost $160.
I'm expecting to spend 30 more dollars on the housing and power cord.
I will post beginning construction, during, after and PAR readings at the end.

If at all possible, could you do a step by step? You're doing a great job right now. I just would like to know kind of step by step how things go.
What gauge wire are you using?

Sure, will do so Seth.
22 awg wire.
This is all new to me too so I will be sure to document everything.

Ok, cool. Thanks!
I really want to get LEDs myself - but I will have to wait to get them for my 110g when the time comes. IF you are serious that what you are setting up is equivalent to two 400w metal halides, I will definitely have to look further into your build and figure out how to do it myself.

I have a buddy down here who sets up rapid leds for a charge and he will be assisting me with everything. I have been learning alot last 3 days let me tell you.
Also actually you can upgrade now and just add more later. That's the beauty of DIY.
I'm getting 4 x 1ft PCB circuit board with 6 LED slots and thinking that you have 36 inch tank, you would just need to get 3 ft then 6 whites, blues, reds, greens, uv and drivers, wires will run you under $100 and later on you can buy 1 more ft long or 2 depending on the length of 110g. (tall or wide) They come with 120 degree lens which will spread every where and put 60 degree lenses on the whites to have them penetrate into the areas that you need to penetrate.
Definitely do-able.
When I upgrade later, I intend to add more to this instead of trying to sell them.

That's cool that you can add more. Great to know. Actually, my 110g is 48"x18.5"x30"tall ... Just letting yah know. :D
Whats your plan on hooking it up to your controller? some kind of cable or wires??

yessir wires.
I'm going to get these babies up and running first and then I'll worry about my Apex. It's a whole another beast that needs alot of TLC if you know what I mean.

I'm going to take my time learning to program the apex the right way and the way that I want it to work.
Also dimensions are same as mine well the width at least so I will try to draw out the layout for you here.

Seth - No worries, buddy. I actually created this for you because you asked. But isn't it why this forum exist? To help others? I'm glad that I'm able to help you out Seth.
Sweat90lx - Thanks for the complement.
Thing about LED is once the bulb goes out, it's hard to replace specially the power LEDs because 1.) they are expensive, 2.) more complicated to uninstall and reinstall
3w leds are easier and cheaper to replace as bulbs run/burn out and also it's much cheaper to make (I'm poor lol) and also you really don't need separate fans on these where as on the power leds, you do. I will have copper on the bottom of aluminum casing to dissipate heat and with good thermal glue, it will do the job that I wanted it to do on regular ac with out compromising on the quality.

Okay thanks for the info. I didnt know they were much different in installing/replacing.
You are doing this on a budget to see how cheap it can be done, you are not poor. lol. Im all about doing things the cheapest and most effective way possible.

Well on the 3w bulb, all I have to to is turn off the driver, remove solder and replace the bulb then re-solder. Really not that difficult.
Where as on pwer LEDs, I would have to (oh I would have to custom make a heat sink btw for power LEDs for my fixture) remove driver, remove heat sink, remove solder, re solder and re do everything back again. More steps and more money to start and to replace. Main factor is more money though lol. I have seen some PAR readings on this lights and I have been very impressed.
No, I just get tired of things quick and I'm always on a budget, I'm poor lol.

That makes sense. We all want to change things and try different options. Ive done a lot of research on leds but there is much more to learn about my tank before I get to building something like you are doing.
If 48 3 watts will be enough for your tank, what I was looking at doing was WAY too much for me. I was thinking about a dimmable driver for the whites/colors and the blues. Ill just tag along and learn for now. lol

You make a good point about the powerpucks... But, at 50,000 hours of illumination, by the time that it goes out, wouldn't you consider getting/building a better unit?

sweat - From my guesstimation from observing other people who have gone this route and my tank size and height and the lenses that I'm using, this should give me around 600ish par near top, 400-500 towards the middle and low 300s by the sand. I'm going to cut this by half on the first week to acclimate properly and raise it slowly every week using a dimmer control.
seth - see, this is the thing Seth. They say 50000 hours but how many people have actually used it to that much? It's proven fact that LEDs will lose their intensity over time and I will test to see how effective they really are and switch out bulbs whenever they do by using par meter every 6 months or so. It will only get cheaper and I can always switch to stronger 5w with the same drivers. (I would need to get couple of more drivers that's all which will cost me about 25 bucks) Good thing about DIY is that it's very flexible.

Ok, cool.
I've always read that it just wavers a little bit in LEDs, but when they are out, they are out. Kind of like a lithium ion battery.

Really? I heard that they were like any other light eventually losing their intensity in time. I will double check later on. :)

Can you post a picture of the custom bars you will mount the LED's on. What are you using now for the tank?

They are at home depot. I will post them as soon as I receive my bulbs and start construction.
I currently have dual 150w MH with 4 t5 with LED supplements (LEDs on this is nothing really)

I'm going to follow this thread until you're finished, and get it tested. For that price I don't think I could pass up having an led fixture. Spending $1500 on two ecotec fixtures is just out of the question for the moment, but i've been dying to have led's for a while now.
