Advice on Ecoxotic Par 38 Led

[Mantis]

Need lighting advice on the two lights below... I am going to setup a 14g biocube mini frag tank...

Mostly LPS... Maybe some SPS high up if any at all... Can I get away with just using the 455nm Royal Blue... Or do I have to have the 12k for beneficial growth?

Blue light is, by the numbers, all you really need to grow coral. Now, that's not to say that other spectrums of light aren't necessary for certain growth functions. Under strictly blue light, there is a possibility for odd coloration or growth patterns. I'm not sure if it has been studied at length or not, but I'd go with a standard "white" lamp to make sure there are no issues.

You can grow SPS under LEDS, but they don't look as nice/color up as well as under lighting systems with more UV... leds lack the UV output that makes SPS so fricken beautiful IME
