I don't know where some people come off slamming LEDs. I have 6 AI Super Sol Blues over my 180 and growth and color are outstanding. Been running these since Feb of this year. I was running 250 Watt SE Radiums before the change. Color temp is similar based on my controller settings.
All colors are outstanding. I have a green slimer that grows out of the water every couple of weeks. I have a plum crazy that is such a deep blue-purple it is not even funny. Orange caps and setosa really pop when the controller ups the blues towards night time. The blue on my blue tip slimer is insane. Pearlberry is awesome, miami orchid, red planet, and others have great color.
The only colony that is not growing well or showing good color is a pink lemonade, but this is about the same as w/ the Radiums.
I think a lot of people try to cheap out and run fewer LED modules than they should. For AIs, one per foot seems about right.
Growth is by no means worse than MH. All colonies are growing as well or better than under my Radiums.
Hope this helps.
