Depending on how many LEDs you wire in series, you could still have lethal voltages present. You show a couple dozen red LEDs in your array; that would give you more than 75V.

50V is considered potentially lethal for humans. I don't know what it is for fish in an aquarium, but I suspect it will be less than 50V with water with impurities involved.

EDIT: added ly to potential

Yess I know, and it is not that I have completely no idea of what I’m doing. I have worked with electronics before but not this kind of stuff. I also work for a company that makes big emergency generators that produce over 2000Kva. So I know how to do it safely but sometimes I don’t know what components fits the job‍

 

100W of LED light? That will blind you and your fish.
A 9W LED light bulb is the equivalent to an old 60W incandescent light bulb. Then 1W equals 6.67W. Then your 100 of LED lights will be the equivalent to 100 x 6.7= 670W of old incandescent light.

No offense intended. Not knowing your qualifications, we make assumptions based on what questions are asked and have an obligation to point out safety issues that should be considered. That's saves us from having someone say that they did what we said and now all of their fish are dead.

Look at the solar rgb from ADA or the vivid 2 (I have a vivid 2 on a different tank) both 130w.
Yess they blind you if you look right into it, but the plants need a lot of light in a nature style aquarium like the ones green aqua makes……

I know! And that it is great that you do it this way! Just wanted to tell you guys that I’m not a complete noob, I just don’t know all of the components on this site of the “hobby” and that’s the reason I sometimes need some help picking the parts

 

Use dimmable drivers, by one for every channel. In each channel should be in series connected LEDs with summary voltage 60 - 80 V.

For each driver use separate dimmer:

Do you know if there are any smaller dimmers? If I need to get 6 of these it get really bulky. Or can you make a simple 0-10v dimmer circuit?

 

Do you know if there are any smaller dimmers? If I need to get 6 of these it get really bulky.

Usually they are assembled in standard wall light switch housing (same dimentions).
You can tear them down and reassemble all components together in one small body frame.

Or can you make a simple 0-10v dimmer circuit?

It is not simple. See examples:

That looks way to complicated to make six times for this project haha.

I will try to tear them down and reassemble them in a smaller box. Thanks for the help! Really appreciate it!
