What are the top T5 HO fixtures currently

[lastlight]

Powermodule and sfiligoi stealth would be the higher end fixtures. I'm thinking the sfiligoi looks better and performs just as well so long as it has individual reflectors and fans. Some of them have shared reflectors and no fans so do your research. I know the 12 bulb ones have both. I also prefer the glass shields of the stealth over the sag prone acrylic in the ati but perhaps that issue has been fixed? Otherwise the powermodule has an edge over the other models. Giesemann matrix has no fans and not much is known about these.
