Thanks bro!
I'll try to change the light on my ATS now, I want to use with LED: color RED and White.
Do you think it would be perfect after ??
or maybe it's better every screen with RED and the other screen with white? cause I use 2 screen (ATS/ waterfall) or combine 2 colors of them?

Red only. Not white.

If you want to add a little blue (435nm) you can.
