Having owned both, for me the spectrum added by the Royal Blue LEDs is clearly superior. The beauty of the AIs is the advanced features of the controller. You can control all three colors individually, creating any coloration desired with the turn of a dial and create custom sunrise/sunset/mid-day PAR increases with or without a separate controller.

Also note there is very little difference in PAR output in fact - Due to the spectrum, the SOL Blues actually deliver slightly more PAR to depth then the Whites.

I have added a couple of 403nm stunner strips to my setup to see what if any impact the addition of the near-UV spectrum would have. It provides a bit more fluorescent pop in the golds and yellow, but I've noted no change in overall coral coloration.

You will LOVE the impact of the Royal Blue LEDs for sunrise/sunset. It far exceeds any coloration I've seen using T5s - It's just spectacular.

I posted a lot more information and photos at varying power that might be of value at http://www.captivereefs.com/forum/li...urements-8268/
