I like the AI. It's super easy to set up.

Tank Dimensions? From what I read you can get a 36" spread using the 30w Radions with 120deg optics.

I went from 8 110 watt VHO on an icecap 660 and 3 400 watt Radiums to a DIY LED Mix.

Generally you want to avoid the Chinese imports as they dont last.

Two Radions will work as they use primarily the better Cree LEDs.

There are other high end options. For a 400 watt MH equivalent you will need about 90 Cree X series LEDs with Quality optics driven at 700-1000mA.

The will give you about 200-250 PAR on the sand bed and with dimmable drivers you can better simulate the solar cycle

Consider the Radions a 175-250 watt MH equivalent with 24"x24" coverage.
