Mike, that's one thing the Spectra didnt offer was the moonlight. These lights were supposedly made for commercial tanks only so they didnt think about the regular consumer. That would definitely be nice if there was a moonlight.
Dudester, I was planning on using the Biomatix. For the full system diagram, I used Sketchup. For the lighting diagram, I used Visio. Both diagrams are to scale. Even the light fixture, reflectors, etc. I did my homework.
Detrivore, they are spot PAR36. The color is amazing with just the 20k on. The corals glow and the color is not too blue. It was the first 2 wks, but that was expected. Its a crisp bluish white. I havent had too much growth yet, but corals respond very well. I have yet to loose any coral, or see one decline in health.
jwc, I didnt ask about the reflectors on the T5's. Looking at the CAD diagram they created, it seems to show something. The Infiniti line is DE, while the Spectra is SE and also wider. DE has a stronger focus point while SE has a broader range. Oh, and I requested that the Spectra have the entire bottom be reflective like the Bilux (diagram shows metal net).
Here's the dimensions:
