[The Grizz]

It is a deffinate gray area for sure.

I didn't like the color of the Nuetral White in my build & have changed them all to cool white, much nicer color mixture with the blues. Nuetral whites have a bit of a yellow ting, where as cool whites are a nice clean white.

As for optics, as far as I'm concerned there are very much needed for all colors except for reds & green. Optics focus the light from the led downward instead of outward. Also any blues used for moon lights don't need optics as you just want the light to spread out wide.
