not to get this thread too far off topic...
I said neither to a make a quick post. It depends what you're looking to do. I wanted a sleek fixture with mounting legs. Back when i bought the acan 104, it was the only option. Now, the maxspect razor is out (obviously copycat style) and has updated led colors. That said, i just downsized to a 60g and went with a new 18" acan 600 and could not be happier. They have all the features of the popular lights including lightning mode, lunar cycle, pre-programs, demo mode, and apex compatibility. So yes, i do think they can compete. If you're looking for colored leds, go with their prism. Imo colored leds are overrated, especially red and green. The only downside to the acans is that you can't swap out leds or optics yourself.
