It's actually not that complicated. I will try to explain, but I am a novice myself. Hopefully others come in and correct the following. Here are the basic components, starting with the LED's themselves:I wish I knew how to build these things and what you are all even talking about. I’d love to try them over my 48/48/24 cube.

- LED board- LEDs are mounted to this board. It needs cooling which I will get to later. Sometimes you can and sometimes you want optics like a lens or a reflector to focus light into the tank. The LEDs on the board need..
- Drivers- To control the LEDs, they need a driver. Think of it as a dimmer control for the LEDs. That is somewhat incorrect, but I think it help conceptualize what's going on. The drivers can be told how much current to output (amount of light output of LEDs) via a pot, PWM input from a controller, just run full blast, and a number of other ways.
- Power Supply- The drivers need a power supply to power them so they can power the LEDs. Just use a good meanwell HLG if you are going to start out with this, or use someone else's specific recommendation. They are very similar to a power brick for a laptop.
- Heatsink- the LEDs make heat, which needs to be shed somewhere. You can use the board on which the LEDs are mounted to share heat with a heatsink onto which they are mounted. There are all sorts. It's a good idea to put a fan on them whether absolutely necessary or not.
