From what i have seen and witnessed. Taking out crap taken care of tanks from friends i have helped come back. And just based on the lights i have noticed. ( and i cant stress this enough. This is an Internet forum. Everyone has their of ideas and thoughts. And this is just from what i have seen )
Radions are over priced crap. My LFS got some and kept bleaching all there sps corals. Leathers loved them though. Finally they changed out one system to vegas and a month later i come walking in and they had vegas on all 8 big coral systems.
I love AI products. Some things are a pain like the wireless controller that HAS to be plugged in to work. But on the part that matters the leds i love them.
Other part i feel it is how they r set to begin with. Most people seem to try and get the tank to look like it did when it had MH over it. What u have to remember is leds only let out the spec of the actual color of that led. So if u have a royal blue led it will only be shooting out the part of the spectrum that is royal blue. Why u see all the diff colors in the new systems not just white and blue now. And make ur % lvls match what the spectrum shows. It will not look like u expect but it will give the corals the right amount and kind of light to help them be healthier. And that is the most important part. If u want to make the tank look more like what u r used to then add a couple t-5 bulbs. But with all leds and matching the spectrum it is going to look very blue in color. My whites at max are only 30% and i just recently turned them up to that a week ago. They were 20% until now.
The 450nm Royal Blue is the grow king. Yes a 5 watt XT-E is much better than a 3 watt Bridgelux knockoff...
Then match this with the Cool White.
Toss in some tertiary LEDs and you can match the mix of any MH,T5 or VHO
The good thing about the right LED Mix is they are brighter than advertised and are very cost effictive.
Finding the right recipe is an art and once done well much better than replacing T5s every 6-9 months.
