Optics or not on 420nm (Violet)

[louisxyz]

On my 24 led fixture, I'll have 60* optics for my Royal Blue, Blue, Neutral White and 12K white combo. But as i wll put only 3 violet 420nm on, should I put optics on them or not?.

Tank is 24" cube.

Thanks

how high is the fixture mounted? id say no optics for max spread on only 3 leds

12" that about just enough so the light doesn't spill over the rim.

I think I"ll go without them, worst case, could order the optics later.

at 12'' you can get decent spread with 80's.. if you havent ordered yet spend the 3 bucks for them now and svae on shipping should you change your mind later.
