It's for a 110, (48 wide x 18 deep x 36 tall). I am wanting to keep soft corals, polyps, and maybe some sps and lps. With the height of the tank I know I am going to need something with some serious light penetration, and I saw the par readings for these on youtube.
If it was me I would definitely look into DIY instead of prebuilt since the cost of getting what's needed is going to be expensive.
Now there are two ways to look at penetration.
1. (just pretend numbers) you have five LEDs, you put very narrow optics on them and they give you the power/punch to get to the bottom of the tank, the negative is that you can get spotlighting with this and shadowing.
2. you can also use ten LEDs with wider optics and then the light will spread and bounce off the glass to get the same amount of light to the bottom of the tank.
to get an idea of what to build consider the phoenix 45 or 55 kits on 2x 18" heatsinks. You can model your own build after the design of the phoenix and just edit out the options you are trying to save money on. etc.
