DIY LED lighting.

Hi to you all Aqualovers..

finally i made my own LED lighting. I just want to show everyone how i made it. I hope someone can get inspired and make better stuffs.

4 pcs red (655-660nm)
4 pcs blue (450-455nm)
12 pcs white LED (12000-15000 K)

Each of them 3w. Lenses are 60 degrees. Fans are 12 V super silent ones. I used heatsink plaster to fixing led's to heatsink.

I think photos are explaining everything but if you need to ask anything I'll try to answer.

By the way I dont have any idea about hanging up whole set. I just hang up everything for demonstration. It woud be great if someone give me an idea about fixing whole set above my tank.

This will be interesting! What tank size is it BTW?
I liked the resultant colour effect, fish might show up better colours in there.

...and any growth in plants noticed yet?

wow looks more bright now. Do you have a journal running? I would like to follow the growth these lights have got to offer over your tank(size?).


...and did you give a though that you'd ve been better off getting a single large heatsink? surely is inspiring, and would love to take in some inputs from here.

Thank you, my jurnal page is "TRAPPED" 85 Liters mid-low tech

Front side is more bright as you say, I put all 4 group in one line. My first though was not like this. Thats why i bought 4 individual heatsink. Surely one long heatsink could be easier and look better.

Anyway back side is little bit dim. I use 1w led's there and didnt use lenses. So they spread white light equally to all background. My tank is 67 x 47 x 27h Cm. So back side of tank is good for other plants but front bit is for HC Cuba and other difficult plants.

I hope everything will be good.

Thanks again to give a comment..

Thanks a lot for the reply.

Here are my few cents in the modified pic. I think too much info in it. The green bolts are ones that attach heatsink to the aluminum channel. And you can run wiring through that channel so that its not visible. The green arrows to bring the drivers over the fan, just that it doesnt look cluttered, + cooling of the fan. The orange hanging wires. Try showing just a single pair of wire, will look more elegant.

Hope it helps

Actually not really, but as you know if you keep your led cooler, it will serve you longer

Hey Saiko thanks for your effort. I will exactly try to do something according to your drawing. Actually big 12cm fan is already blowing to the drivers on both side and keep them cool. But as you say i can make something more "elegant"

Thanks a lot my friends..

I will post here new version soon

Good stuff. Im just starting to research on how to make a good diy led. Very nice tank you have.

You have 20, 3w over your tank. How many gallons is it? How long have you been growing your HC under it? any algae problems? I always thought leds werent powerful enough to go over high light requiring plants.

Thanks,
Its 85 Liters (sorry Im using liter) Tank and lighting is new, I just add HC about 1 week ago. There was some algea, always appear in new established tank you know, like spider web. But its gone. Tank is very clear now. Led's are really powerful, just you need to choose right LED and right LENS on them. Actually this tank will be good experiment about LED's on Planted tanks. We will see together.

I know, they will work even without fans. I just wrote before. Extra cooling is not harmful right? Theres two way to make your led's longer life, Choose the correct driver, and keep them cool. So they are really cool when they work. Even I can touch them without burning. But Its impossible when fans off... I tried this personally...

Fans are super silent as well...
