LEDS are pretty and energy efficient. I dont know that fixture. That LED is .06 WATT per LED and couldnt find the light spectrum. Its probably not REEF ready but I coould be wrong.
Looks like it would be great for fish only tank.

Based on my experience I can offer 3 choices.
1. Marineland REEF LED fixture. Look at the website for REEF specs. These are 1WATT LEDS and do great for shallow tanks to grow coral. I have one and I like them.
2. The AOI is what I want. These have 3WATT LEDS and automatic controller for different parts of the day. Little more expensive but I want them.
3. diy A lot of websites are offering DIY LEDS. I have not done this yet but it could cut your cost in half. I would like to do this too.
