early part of the article articulates the reasons why 400-500 is important to most corals.
Note that royal blue and blue LEDs are in the 450nm range, so will NOT cover the 400-425/435nm range. Thus the need for violets.
now the LEDs they measured were properties for the SPECIFIC LEDS they measured, NOT for all LEDs. so you have to read the fine details on LEDs you want to buy. the spectral spread from the peak spectrum assume it to be 10nm from center either side, and not more as LEDs have very narrow spectrum output. That's where care needs to be I think.
Red spectrum article is from the same magazine, feb. 2013 edition feature article. long article, it wasn't the central part of the experiment they were doing, but a by-product, and very educational. Again, you have to read carefully.
