I've been using Ecoxotic for a couple years now, and honestly I wouldn't buy any of there products again. The growth rate for corals is poor compared to T5's and MH, and the leds in the strips keep having issues. That goes for the panorama pros and original. Out of 13 different modules (including warranty ones), I've had issues with 12. LEDs go dim, burn out and so on. Ecoxotic tries to blame me, they say it's an electrical issue (even thought I have a 20 amp dedicated breaker), a heat issue (even though I have two 4" fans on my canopy) or user error. My LFS runs them on their tanks, and they've had similar led issues. Just a warning, but only my experience. Also, I took pictures and kept a log on growth rates, and I saw probably an 80% drop in growth rate from MH and T5's. The corals lived, but growth slowed considerably.
