LED unit For ADA 60-P|| Ordered stuff.


Hello people,
After a lot of reading on LEDs and all the build threads here, I also want to go with LEDs for my new project. It's been a month that I'm reading and planning on what to buy and from where. So just sharing my 'LED shopping list' with you all-
I'm gonna make a MakersLED for my 60-P.[24"x12"x14"]. The substrate layer would be 2-3" high.
Here's what I've decided to order-

1. MakersLED Heatsink 12"-------------------------------------X 1
2. 12V 500mA DC supply for the fan----------------------------X 1
3. XT-E Royal Blue--------------------------------------------X 4
4. XT-E Cool White -------------------------------------------X 3
5. XT-E Warm White ------------------------------------------X 5
5. Optics for XTE, 60 degree---------------------------------- X 12
6. Inventronics 40W, 700mA Driver-----------------------------X 1
7. AC Plug for the Driver---------------------------------------X 1
8. DIM4 sunset/sunrise controller-------------------------------X 1
9. 12V 500mA DC supply for DIM4------------------------------X 1
10. Solder, solder wire, thermal grease.



So there will be a lot of Red plants.

According to Hoppy's Calculator- at 2" spacing and 3 rows, I'll be getting PAR reading of 113 if 60 degree optics are used and the light unit hanged at 18" from substrate.
My Driver can take 15 LEDs and with remaining 3 ports of DIM4 I can light 9 more LEDs.
Heatsink will be 12"x6" and the tank is 24"x12"x14"

So the part where I need your help is-
What colors to use so that my Red color plants be Red as they are in above picture ?
Do I need to add Red LEDs also in my shopping list ? How many of them ?
And what would be the best layout to put them all to make the Disco dead.
Somebody said- "It will take full sun to keep them this Red". I hope that is not correct. I wil give lots and lots of CO2 (Reg from Bettatail is on the way). I'll dose with ADA ECA+ Pfertz Macro solution. I want to give the best spectrum to the plants that they need without activating the Algae bloom.

Sumer.

There is some good discussion in this thread :
http://www.plantedtank.net/forums/sh...d.php?t=184629

I cant tell you definitively what always works, but this is what worked for me.

I would suggest going with warm whites, neutral whites and cool whites in a ratio of 1 : 2 : 1 , A couple of blue moonlight led's should give you the crisp clear look you want.
Red's can be added just one or two at the most. The blues should complement the reds.
1: 1 for blue to red.
Do not go overboard on the blue to red led's, two for a 16" heatsink is enough.

Thanks for the link. You had to shut your tank :/ Your tank could've given some amazing results and I would've got my answer.
Anyways would anybody else throw some light on the ratio of colors to be used !!

Hey Sumer-
I am currently building an LED light for my Fluval Ebi. I have tried numerous color combos and honestly most of them have turned out ugly haha. Also I mixed my led with Philips Luxeon and Cree XP-G so I can't really advise you on # of leds for desired brightness. But, I will try and help you out as much as I can!

First off I would definitely make sure to use Warm White, Cool White, Royal Blue, Deep Red, and Green.
Warm whites help add some warmer colors such as red, orange, and yellow which will help your red plants show nice color. Using 1:2 ratio of ww to cw will look good. I find the yellow to be a little much for me (even the 6500k were pretty yellow) so I added a couple of Luxeon green leds. Works very well. Add deep reds and royal blues to taste I would stay away from cool blue. It washes color out and can make the water look hazy.

I think by cool blue you mean cyan.
BTW thanks for telling the results of your experiment. would definitely keep this in mind.

In my experience NW bring out deep reds just fine. I'd only use warm white if you were simulating the look of morning sun, Otherwise it just looks too warm with the WW.

No, I mean Luxeon cool blue. Cyan is totally unnecessary for a planted tank though though. Neutral whites do bring out reds but I couldn't keep my Rotala sp. Mini "butterfly" very red with neutrals. It took 2700k to bring out its best dark red color! But I agree with you Pwolfe, warm white can definitely be too warm without a good balance of LEDs.

I think I will mix CW:WW:NW in the ratio of 1:1:2 with some Blues and OCWs. Hope it would help in making the plants Red.
The blues would also be used as moonlights at night.

So, finally the shimmering effect and my DIY instincts won the fight against T5s. Haha. ordered the led stuff. Lets see how well these LED grows the red plants.

And just to let you all know- here's what I've decided to go in with-

6 Neutral whites
3 Cool whites
3 warm whites
4 Royal blue
2 Reds
2 Ocean Coral whites



The unit will be at 9" from the tank (in the figure it's at 6").
Sorry I'm not good at making 3D models in computer so had to go with paper drawing.

Thanks,
Sumer.

looks like a great start! You could even try doing the reds with out optics since there's only 2 of them

At first I thought of putting 80 degree optics. But after making this diagram I decided that the reds will be used without any optics.
