I will agree. After some research the AI prime may not be what I want. What do you think about the WILLS light above? It has more PAR and better coverage.
Glad you are getting away from the Primes. Total waste of money there. Sorry I can't help you with the others listed as I have no experience with them. As far as LEDs go I only have personal experience with the following:
AI - Favorite color spectrum and software but worst quality light regarding build and durability/longevity, will never give these thieves more of my money.
Ecotech - Second favorite color spectrum but too expensive.
Kessil - Only good thing I can say about these lights is they seem to last. Absolutely hate the spotlight look of tanks under these lights.
Reefbreeders - system I am currently running. not a huge fan of the spectrum and overall look of the tank light but would get it above all others listed above considering price and quality reputation. Coral colors do look as good/better as any other light above.
Cheap $125 Black Box - I ran these the longest and would suggest to any beginning reefer. Can grow absolutely anything and they are super cheap. Can also sell in less than a day on craigslist/facebook for $50-75 per fixture if you ever decide to upgrade. Maybe you can buy a used one that is a year or two old to test out.
Only downside, and not sure it is still true, but it was for my fixtures that I got a bout 6-7 years ago; they are cheap leds and the colors of some of the corals wont look quite as stunning as the other fixtures above (red/yellow especially).
I experienced better growth with these cheap lights though as the spread is much better than the expensive fixtures above.
There is some other expensive fixture I currently have sitting in storage but I can't remember the name of it. I'll come back and edit if I can remember. Was such a lousy light I ran it for about 3 months. Grew nothing but nuisance algae.
