i dont have experience with any of them really, but...
from what i have gathered, the Reefoptix is most likely the best reflector available for the HQI bulbs.

having said that, i have a Hamilton Reefstar pendant sitting on the floor next to me right now, i havent used it on a tank yet, but will be on my new tank after i move. i've fired it up once just to see, and it was pretty bright and i was quite pleased with the color.

p.s. i bought the hamilton because it is all packaged together as a single unit, plug and play.
