What spectrum lights for my LED actinics?

[Gripenfelter]

I have the eshine systems lights wil 10,000 K white and 455 nm Royal Blues.

Looking to get some actinics in maybe a 420 nm and 465 or 470 nm?

What spectrum would best benefit me? I have LPS and SPS.

Anything 420 and below will just get washed out with the other other LEDs on. the 455 RBs are enough for an actinic effect. I would add some blues if you're looking for more light, I'm guessing those are around 465-470nm. If you'e looking for effect only consider some reds.
