Hello all thread-viewers,

my idea was to build a DIY-LED with COB's and make it kinda special. So i decided to watercool the COB's which some of u alrdy guessed, get pretty warm.
Since the COB's are more efficient when cooled better, watercooling was my only option to go. These COB's are all connected to one dimmer to power them up from 10 to 100% power.

But not enough, i wanted to add some monos which should be dimmable. Since there are so many different wavelengths that could play a possible role
in growing plants i couldnt decide between them and added 12 different wavelengths in total of 60 LED's.These LED's get cooled passive with some
mini heatsinks since they are all capped at 3W and dont need that much cooling. Also they get a lot of flowing air from the watercooling-system of the COB's.
So there are 5 LED's per wavelength which are all connected to 1 dimmer to power up one wavelength from 0 to 100% power.

So in total i got this:

5x COB ( Cree CXB3590 | 4x 3500K, 1x 5000K ) with 90° angelina reflector
5x Watercooling-System ( Alphacool Eisbaer 120 CPU unit including 1x Pump inclusive watertank, 1x radiator, 1x 120mm fan [ in the pack are included 2 fans but i only need 1] )

60x Mono-wavelength LED ( 5x 390 nm, 5x 410 nm, 5x 430 nm, 5x 440 nm, 5x 455 nm, 5x 490 nm, 5x 590 nm, 5x 600 nm, 5x 630 nm, 5x 660nm, 5x 740 nm, 5x combined 400-840 nm )
60x mini-heatsink passive

13x dimmer ( 1x for the big COB's, 12x for the monos )

3x power supply ( 1x Meanwell HLG-240H-C1400B, 1x Meanwell SP-240-24, 1x Meanwell RS-50-12)

Since this is a prototype and i couldnt do any testing up to now, i mounted all of this on a wooden plate and framed it with a wooden frame to stabilize it.
The size of the completed build is about 93x93cm ( 3x3 ft).

Coverage:

I did some testings with thie lamp about 60cm above the ground and came out with approx. 1,2x1,2m (4x4 ft best coverage ) to 1,5x1,5m (5x5 good coverage ).

I will update/edit this thread with some pictures.

So here are the promised pictures, sadly u cant see anything from the monos with the camera when complete build is at 100% but with the naked eye u can :D

Closer view on COB in center:

So please tell me what u think about and/or ask questions.

@TheMongol : so it's done, i posted the lamp here in the forum and we will see what ppl think about :)

I also decided to make some pictures of the different monos at 100% power but i need to make one thing sure, with the naked eye u can see much more differents between the different wavelengths.

5x 660nm,

5x 740 nm, ( since infrared is mostly not visible for the human eye i had to make the pic like this )

5x combined 400-840 nm

here a pic of all 12 different wavelengths at once:

Hey bro

Nice rightup lots of cob builders around here.

Funny when I first read water cooled, I had an image of a radiator with one fan and then the liquid actually coiled somehow around the heat sink.

We have a section on the forum for live introductions where you can introduce yourself and put up a link to your thread.

We also have a section called live Stoners gossip and there's always a lot of activity in there you can say hello in there and post up a link to your thread you get a lot of viewers real quick.
