28 months this way, but it took six months to get there.
Started at 50 blue 25 white........then up 5% every two weeks.
Nothing bleached, or at least, thus far.
CCB, don't push the same higher par as the main streams like kessel and AI.
I'm 14" off the surface, a little high but these lights diffuse better when a bit higher.
Plus they don't get splash as much.
