Aww I run 14k LEDs. And he's in the bottom of my 25 cube. He's not right under it either. I don't think there's a way to turn down the intensity.
Wish I had more blues though.
its most likely a non issue. I put mine in and the second day it did that right after peak intensity. next day same thing. then nothing fora couple days, reduced my lighting and havent seen it happen at all.
