I have 2 FTS in my thread :

I don't know if it really shows much of the spotlight look, this is a standard 20g tank though. I'm sure it would be more noticeable on a larger tank... you can somewhat see a spotlight effect in the picture.
edit: sorry forgot to answer your question. What I
don't like about the fixture, is the fact that I have no open top, I really love to be able to work in my tank without hassle. It becomes a huge pain. Adding top-off water is a PAIN (daily chore) because I have to take the fixture off every time to dump the water in. I don't like the fact that because my tank is so shallow and because I have the 150w HQI and actinics, it is all too much light and gives my water a cloudy effect (may not be like this for you.... ) There are a few drawbacks for me
