Led NM Choices

I submitted another thread on the layout, now I'm looking for suggestions on what nanometer leds to use.



I plan to use blue, royal blue, purple, and UV. I'm looking for the UV NM that will bring out the most fluorescence. I know to use 450nm royal blue, other than that I'm at a loss on what I should get. Let me know what you used and/or what you like best.
